Auto recode a variable in a GADSdat.

Auto recode a variable in a GADSdat. A look up table is created containing the respective recode pairs. An existing look up table can be utilized via template. This function somewhat mirrors the functionality provided by the SPSS function autorecode.

Usage

autoRecode(
  GADSdat,
  var,
  var_suffix = "",
  label_suffix = "",
  csv_path = NULL,
  template = NULL
)

Arguments

GADSdat

A GADSdat object.

var

Character string of the variable name which should be recoded.

var_suffix

Variable suffix for the newly created GADSdat. If an empty character, the existing variables are overwritten.

label_suffix

Suffix added to variable label for the newly created variable in the GADSdat.

csv_path

Path for the .csv file for the look up table.

template

Existing look up table.

Value

Returns a GADSdat object.

Details

If an existing template is used and a look up table is saved as a .csv file, the resulting look up table will contain the existing recodes plus additional recode pairs required for the data.

Examples

gads <- import_DF(data.frame(v1 = letters))

# auto recode without saving look up table
gads2 <- autoRecode(gads, var = "v1", var_suffix = "_num")

# auto recode with saving look up table
f <- tempfile(fileext = ".csv")
gads2 <- autoRecode(gads, var = "v1", var_suffix = "_num", csv_path = f)

# auto recode with applying and expanding a look up table
gads3 <- import_DF(data.frame(v2 = c(letters[1:3], "aa")))
gads3 <- autoRecode(gads3, var = "v2", csv_path = f, template = read.csv(f))
#> Warning: For variable v2 the following values are in the lookup table but not in the data: d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z
