What can people tell me about converting back slashes to forward
slashes in character strings?
Several years ago, Prof. Ripley provided a solution, which I lost
and have not been able to find.
Below please find a function to do this. I do not find this very
satisfactory, however, because it uses "scan" and therefore operates on
an input not a character string. Unless someone suggests something
better, I plan to add this to the "sos" package and issue a new release
very soon. (The new release is needed, because the RSiteSearch
capability has been modified in a way that breaks the current "findFn"
core of "sos".)
back2forwardslash <- function (nmax = 1, pattern = "\\", replacement =
x <- scan(what = character(), quote = pattern, nmax = nmax)
x. <- gsub(pattern, replacement, x, fixed = TRUE)
paste(x., collapse = " ")
(x <- back2forwardslash())
# nmax must be one more than the number of embedded blanks
(x3 <- back2forwardslash(3))
