Description

These functions help in adding, modifying or removing variable definitions in a configuration object obtained with ConfigFileOpen or ConfigFileCreate. ConfigEditDefinition() will add the definition if not existing.

Usage

ConfigEditDefinition(configuration, name, value, confirm = TRUE)

ConfigRemoveDefinition(configuration, name)

Arguments

configuration

Configuration object obtained wit ConfigFileOpen() or ConfigFileCreate().

name

Examples

# Create an empty configuration file
config_file <- paste0(tempdir(), "/example.conf")
ConfigFileCreate(config_file, confirm = FALSE)
# Open it into a configuration object
configuration <- ConfigFileOpen(config_file)
# Add an entry at the bottom of 4th level of file-per-startdate experiments 
# table which will associate the experiment "ExampleExperiment2" and variable 
# "ExampleVariable" to some information about its location.
configuration <- ConfigAddEntry(configuration, "experiments", 
                "last", "ExampleExperiment2", "ExampleVariable", 
                "/path/to/ExampleExperiment2/", 
                "ExampleVariable/ExampleVariable_$START_DATE$.nc")
# Edit entry to generalize for any variable. Changing variable needs .
configuration <- ConfigEditEntry(configuration, "experiments", 1, 
                var_name = ".*", 
                file_path = "$VAR_NAME$/$VAR_NAME$_$START_DATE$.nc")
# Now apply matching entries for variable and experiment name and show the 
# result
match_info <- ConfigApplyMatchingEntries(configuration, 'tas', 
             exp = c('ExampleExperiment2'), show_result = TRUE)
