modify_xpdb: Add, remove or rename variables in an xpdb

In xpose.xtras: Extra Functionality for the 'xpose' Package

Add, remove or rename variables in an xpdb

Description

mutate_x() adds new variables and preserves existing ones. select() keeps only the listed variables; rename() keeps all variables.

Note: this function uses xpose.xtras::edit_xpose_data, but is otherwise the same as <xpose::mutate>.

Usage

mutate_x(.data, ..., .problem, .source, .where)

rename_x(.data, ..., .problem, .source, .where)

Arguments

.data	An xpose database object.
...	Name-value pairs of expressions. Use NULL to drop a variable.
.problem	The problem from which the data will be modified
.source	The source of the data in the xpdb. Can either be 'data' or an output file extension e.g. 'phi'.
.where	A vector of element names to be edited in special (e.g. .where = c('vpc_dat', 'aggr_obs') with vpc).

Value

An updated xpose data object
