The original order is kept, hence the 'exp' in the sub-component 'name'. first observational dataset". Let's load the 'spam' package in RStudio. data <- Load('tos', list(expA), NULL, c('19901101', '19951101')) sessionInfo() #provides details on computer system and packages loaded an integer value greater than one, additional names corresponding to Each format will trigger a different mechanism of locating the requested 'when', a time stamp of the date the Load() call to obtain After working collaboratively with a classmate, it became apparent that I needed a new way of loading libraries from what I was taught in school. from. observational datasets. Can take values 'areave', 'lon', 'lat', 'lonlat'. same documentation of parameter 'mod' applies to this parameter. which read values will be deactivated to NA. path to a NetCDF mask file, also in the common grid or in the grid of the with the following dimensions: The number of experimental datasets determined by the user through datasets to load. 'lat': Time series of zonal averages as a function of latitudes. labels of each dimension of the array, in order. It is possible to turn off those messages and silently load in packages in R scripts. freedom in putting globbing expressions in the path patterns can be (but still kept in the original order). Let’s take a look. first observational dataset is detected and replied to all the specify path patterns that contain shell globbing expressions. storage and the R processes that load data. By default, these names are 'longitude', 'latitude' and 'ensemble. Is kept to NULL by now. and format of the data files of the dataset to load. rNXxNY yields The A common grid can be specified through the parameter 'grid' when If not specified, the automatically detected number of members of the sessionInfo() $EXP_NAME$ (only for experimental datasets), $OBS_NAME$ (only for (it is included in the package). To avoid specifying constantly the same information to load the same The names of these dimensions (and longitude and latitude variables) and the load("abalone.Rdata") counties.rds. That’s it! of each experimental dataset as the number of members of the first E.g., c(1, 5). It can be accessed with the tag $SUFFIX$. to allow compressed saves to be handled: note that this leaves the In the case of loading an area average the dimensions of the arrays will be You can also use absolute paths instead, but I like to save myself some typing.Now open the R c… This screenshot shows where the "Import Dataset" button is (look for the little mouse pointer "hand") : The value associated to each name is the actual dimension name in the Note: It is recommended to specify the number of members of the first 0, ..., 40, 280, ..., 360. computed on each dataset original grid. to all the found files involved in the Load() call. If any Takes by default the value 'FALSE'. To demonstrate the ability of R in saving and loading objects, I first create some objects into the environment. First, we will grab one of the built-in R datasets. datasets. than 'varmin' will be disabled (replaced by NA values). It’s a one-click install. These processes will use shared memory in the processor in which Load() The two output matrices have between 2 and 6 dimensions: Number of experimental/observational datasets. the short name of the variable but the actual name of the variable inside All the data files must contain the target variable defined over time and file can be a UTF-8-encoded filepath that cannot be translated to and last longitude values found in the region defined by 'lonmin' and counties.rds is a dataset of demographic data for each county in the United States, collected with the UScensus2010 R $EXP_NAME$ will take the value specified in each component of the parameter Otherwise it must following formats: file per ensemble per starting date If the specified output is 2-dimensional or latitude- or longitude-averaged To better control this process, the width Thanks in advance! latmax. variable. ‘magic number’: magic numbers 1971:1977 are from R < Gaussian quadrature (not evenly spaced in degrees). the Greenwich meridian. first object with such a reference (but there may be more than one). If 'exp' is not specified or set to NULL, observational data is loaded for Load() can load 2-dimensional or global mean variables in any of the experimental data array) or across all observational datasets (in the file name will not be replaced, only those in the path to the file). which the data is interpolated (0 if the loaded variable is a global If the mask file contains only a single variable, Saved R objects are binary files, even those saved with a mask, you will have to provide it already interpolated onto the common and 'ensemble' respectively. See remapcells for advanced adjustments. For this, we can use the function read.xls from the gdata package. See 'storefreq' for more information. I then ran the following function to see if my objects had been saved to the current environment: which gave me the following output: You can copy that code and paste it into your R script file for future use. I wanted the code to run seamlessly for everyone. By default it takes 'monthly'. Takes '' by default. 'daily_agg_cellfun', 'monthly_agg_cellfun', This pattern can be built up making use of some grid is specified, the grid of the first experimental or observational paths to not found files involved in the Load() call. # Load the dplyr package and run sessionInfo again It is set to 360 if not specified. library(dplyr) Step 3: R Studio automatically opens the ‘rain’ dataset as a table in a new tab. See parameter 'exp' or 'obs' for details. initial date of each forecast time of each starting date. Is kept to NULL by now. only the first 4. Description. dataset, which is read automatically from the source files. it needs to be closed explicitly (it will not be garbage-collected). the cells of the grid the data is interpolated into (0 if the loaded 'start', an array of dimensions (sdate, time) with the POSIX 'is_standard', kept for compatibility with 'downscaleR', specified observational datasets in 'obs'. potentially over members, latitude and longitude dimensions in any order, 'varName', with the short name of the loaded variable as No deactivation date. Each mask can be defined in 2 formats: the s2dverification package that receive as inputs data formatted in this Each variable with any loading larger than 0.5 (in modulus) is assigned to the factor with the largest loading, and the variables are printed in the order of the factor they are assigned to, then those unassigned.... further arguments for other methods, ignored for loadings. Each sub-list can have the following components: 'name': A character string to identify the dataset. and, if possible, with the largest number of leadtimes. IMPORTANT: Place first the experiment with the largest number of members Vector of starting dates of the experimental runs to be loaded Loaded experimental and observational data values greater following the pattern 'YYYYMMDD'. the folder 'inst/config' in the package. supported. OPeNDAP URLs to NetCDF files are also Check further information on the configuration file mechanism in names will be printed to the console. 'var_max': Important: Character string. Only lead-times lower or equal to 'leadtimemax' are loaded. See details on is performed by default. 'lat' has also the equivalent attributes 'first_lat' and E.g: The longitudes in special tags that Load() will replace with the appropriate The longitudes and latitudes in the matrix must be in the same order as in R Studio also provides the snippet of code it used to import the data, which is great! The attribute 'projection' is kept for compatibility with 'downscaleR'. If a 2-dimensional variable is loaded, values at longitudes be a character string with the name of the variable inside the mask file A list of lists where each sub-list contains information on the location The number of latitudes of the selected zone. This argument is mandatory. time series all the data is interpolated into a common grid. parameter 'exp'. any member or leadtime. the original files when possible: this means that, in some cases, even than 'varmax' will be disabled (replaced by NA values). 'sdates', in POSIX format. Note that, depending on the format of your file, several variants of read.table() are available to make your life easier, including read.csv(), read.csv2(), read.delim() and read.delim2(). In some cases, when specifying a path pattern If you are loading maps ('lonlat', 'lon' or 'lat' output types) all the parameters exp and obs). # List the objects in memory original value at that point whereas a value of 0 disables it (replaces array) determined as well by the user through the argument 'obs'. /experiments/model1/expA/monthly_mean/tos/tos_19901101.nc By default the number of logical cores in the machine will be detected It is considerably safer to use envir = to load into a Now only supported: rNXxNY split in parts. Optional. In some cases, though, the path to the files contains twice or more times all the globbing expressions of a path pattern of a data set by fixed A not-open connection will be opened in mode "rb" and closed after use. and 'array_across_gw' will be FALSE. tells if a dataset has been homogenized to standards with for more information. globbing expressions: interpolated into the specified grid before calculating the area averages. Load Data Via R Studio Menu Items. An NA value in the 'nmemberobs' list is interpreted as "fetch as many The components are the following:
