recode_sex recodes a binary sex variable for a given source column in a data frame or data table.
Useful in transforming output from growthcleanr::cleangrowth() into a format suitable for growthcleanr::ext_bmiz().
recode_sex(
input_data,
sourcecol = "sex",
sourcem = "0",
sourcef = "1",
targetcol = "sex_recoded",
targetm = 1L,
targetf = 2L
)a data frame or data table to be transformed. Expects a source column containing a binary sex variable.
name of sex descriptor column. Defaults to "sex"
variable indicating "male" sex in input data. Defaults to "0"
variable indicating "female" sex in input data. Defaults to "1"
desired name of recoded sex descriptor column. Defaults to "sex_recoded"
desired name of recoded sex variable indicating "male" sex in output data. Defaults to 1
desired name of recoded sex variable indicating "female" sex in output data. Defaults to 2
Returns a data table with recoded sex variables.
