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
)

Arguments

input_data

a data frame or data table to be transformed. Expects a source column containing a binary sex variable.

sourcecol

name of sex descriptor column. Defaults to "sex"

sourcem

variable indicating "male" sex in input data. Defaults to "0"

sourcef

variable indicating "female" sex in input data. Defaults to "1"

targetcol

desired name of recoded sex descriptor column. Defaults to "sex_recoded"

targetm

desired name of recoded sex variable indicating "male" sex in output data. Defaults to 1

targetf

desired name of recoded sex variable indicating "female" sex in output data. Defaults to 2

Value

Returns a data table with recoded sex variables.

Examples

# Run on given data
df <- as.data.frame(syngrowth)

# Run with all defaults
df_r <- recode_sex(df)

# Specify different targets
df_rt <- recode_sex(df, targetcol = "sexr", targetm = "Male", targetf = "Female")

# Specify different inputs
df_ri <- recode_sex(df_rt, sourcecol = "sexr", sourcem = "Male", sourcef = "Female")
