By default, to_character() is a wrapper for base::as.character().
For labelled vector, to_character allows to specify if value, labels or labels prefixed
with values should be used for conversion.
to_character(x, ...)
# S3 method for double
to_character(x, explicit_tagged_na = FALSE, ...)
# S3 method for haven_labelled
to_character(
x,
levels = c("labels", "values", "prefixed"),
nolabel_to_na = FALSE,
user_na_to_na = FALSE,
explicit_tagged_na = FALSE,
...
)Object to coerce to a character vector.
Other arguments passed down to method.
should tagged NA be kept?
What should be used for the factor levels: the labels, the values or labels prefixed with values?
Should values with no label be converted to NA?
user defined missing values into NA?
If some values doesn't have a label, automatic labels will be created, except if
nolabel_to_na is TRUE.
v <- labelled(c(1,2,2,2,3,9,1,3,2,NA), c(yes = 1, no = 3, "don't know" = 9))
to_character(v)
#> [1] "yes" "2" "2" "2" "no"
#> [6] "don't know" "yes" "no" "2" NA
to_character(v, nolabel_to_na = TRUE)
#> [1] "yes" NA NA NA "no"
#> [6] "don't know" "yes" "no" NA NA
to_character(v, "v")
#> [1] "1" "2" "2" "2" "3" "9" "1" "3" "2" NA
to_character(v, "p")
#> [1] "[1] yes" "[2] 2" "[2] 2" "[2] 2"
#> [5] "[3] no" "[9] don't know" "[1] yes" "[3] no"
#> [9] "[2] 2" NA
