[R] Find and replace backslashes XXXX

[Thierry Onkelinx]

Since the character looks like a Windows file path, you could use
normalizePath() instead of gsub().

normalizePath("X:\\Classes\\TT\\Automation", winslash = "/", mustWork =
FALSE)

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
~ John Tukey
