set_var_types.xp_xtra: Set variable types

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

Set variable types

Description

<set_var_types> wrapper that accepts tidyselect syntax. Character vector-based selection still works.

set_var_types_x accepts xpose_data or xp_xtras objects.

set_var_types without ⁠_x⁠ is defined with S3 methods. To maintain xpose expectations, the default method is <set_var_types>, but if an xp_xtras object is used, the method uses set_var_types_x.

Usage

## S3 method for class 'xp_xtras'
set_var_types(xpdb, .problem = NULL, ..., auto_factor = TRUE, quiet)

Arguments

xpdb	An xpose_data object.
.problem	The problem number to which the edits will be applied.
...	<dynamic-dots> Passed to set_var_types after processing.
auto_factor	If TRUE new columns assigned to the type 'catcov' will be converted to factor.
quiet	Logical, if FALSE messages are printed to the console.

Value

An xpose_data object

Examples

data("xpdb_ex_pk", package = "xpose")

# Change variable type
xpdb_2 <- set_var_types_x(
  xpdb_ex_pk, .problem = 1,
  idv = TAD,
  catcov = starts_with("MED"),
  contcov = c(CLCR,AGE)
  )
