Use parse_*() if you have a character vector you want to parse. Use
col_*() in conjunction with a read_*() function to parse the
values as they're read in.
parse_logical(x, na = c("", "NA"), locale = default_locale(), trim_ws = TRUE) parse_integer(x, na = c("", "NA"), locale = default_locale(), trim_ws = TRUE) parse_double(x, na = c("", "NA"), locale = default_locale(), trim_ws = TRUE) parse_character(x, na = c("", "NA"), locale = default_locale(), trim_ws = TRUE)
| x | Character vector of values to parse. |
