reorder_levels_params(df, paramcd_levels)

Arguments

df

data.frame with PARAM and PARAMCD variables

paramcd_levels

ordered levels of PARAMCD

Examples

str(reorder_levels_params(df, paramcd_levels = c("B", "A", "C")))
#> 'data.frame':	3 obs. of  2 variables:
#>  $ PARAMCD: Factor w/ 3 levels "B","A","C": 1 2 3
#>  $ PARAM  : Factor w/ 3 levels "letter B","letter A",..: 1 2 3
