R help - Sep 2011 - Removing special chars in strings?

Hi all,

How can I replace those "\" in the str?

Thanks in advance.

func <- function(str) {
  print(gsub("\\","",str))
}
func("bla\ble\bli")

I usually use something like [\\]

There are no backslash characters in the string "bla\ble\bli".
"\b" is used to indicate a backspace character, just
as "\n" is used to indicate a newline character.

You can get rid of the backslash characters with
  > gsub("\b","","bla\ble\bli")
  [1] "blaleli"
or change them to b's with
  > gsub("\b","b","bla\ble\bli")
  [1] "blablebli"
