helper for writing arm mapping and ordering code.

Provides lines of code for left hand side of arm mapping. user must provide right hand side

Usage

maptrt(df_armvar, code = c("M", "O"))

Arguments

df_armvar: the dataframe and column name containing treatment code. e.g. ADSL$ARMCD
code: controls whether mapping or ordering code is written to console. Valid values: "M" and "O".

Value

Data frame with the unique treatment codes. The function prints the left hand side of the mapping or ordering code to the console.

Details

SPA configure study specific pre-processing for deploying goshawk. writing the code for ARM mapping and ordering is tedious. this function helps to get that started by providing the left hand side of the mapping and ordering syntax. call the function and then copy and paste the resulting code from the console into the app.R file.

Examples

ADSL <- teal.data::rADSL

# get treatment mapping code
maptrt(df_armvar = ADSL$ARMCD, code = "M")
#>               
#>  "ARM A" = "",
#>  "ARM C" = "",
#>  "ARM B" = "",

# get treatment ordering code
maptrt(df_armvar = ADSL$ARMCD, code = "O")
#>                       
#>  ARMCD == "ARM A" ~  ,
#>  ARMCD == "ARM C" ~  ,
#>  ARMCD == "ARM B" ~  ,
