Base64 Decode

Source: R/base.R
base64dec.Rd

Decodes a character string, raw vector or other object from base64 encoding.

Usage

base64dec(x, convert = TRUE)

Arguments

x

an object.

convert

[default TRUE] logical TRUE to convert back to a character string, FALSE to convert back to a raw vector or NA to decode and then unserialize back to the original object.

Value

A character string, raw vector, or other object depending on the value of ‘convert’. If conversion to a character string fails, a raw vector will be returned instead (accompanied by a warning).

Details

The value of ‘convert’ should be set to TRUE, FALSE or NA to be the reverse of the 3 encoding operations (for strings, raw vectors and arbitrary objects), in order to return the original object.

#> [1] "secret base"
base64dec(base64enc(as.raw(c(1L, 2L, 4L))), convert = FALSE)
#> [1] 01 02 04
base64dec(base64enc(data.frame()), convert = NA)
#> data frame with 0 columns and 0 rows
