dropQueries: Drop specified queries from scenarios.

In JGCRI/rgcam: Tools for importing and working with GCAM results

Drop specified queries from scenarios.

Description

This function removes the specified queries from a data set. By default the queries are removed from every scenario they appear in, but the operation can be limited to certain scenarios if desired. If the operation is performed on a file, the file is also modified. If it is performed on a data set that has already been loaded, then the change is written back to the file only if writeback is set to TRUE. Either way, the modified data set is returned.

Usage

dropQueries(
  proj,
  queries,
  invert = FALSE,
  writeback = is.character(proj),
  scenarios = NULL,
  invertScenario = FALSE
)

Arguments

proj	Project data or data file name.
queries	Name(s) of the queries to drop.
invert	If TRUE then delete all queries except the ones in queries.
writeback	If TRUE then write the change to the backing data file.
scenarios	Drop the queries only from the specified scenarios (default is to drop from all scenarios).
invertScenario	Drop queries from the scenarios not listed in scenarios.

Details

As with dropScenarios, it is possible and perhaps occasionally useful to specify a file but to force the file not to be updated by specifying writeback=FALSE.
