How to use sub, gsub, etc. to replace "\" in a string to "/"?
For example,convert "C:\foo\bar" to "C:/foo/bar".
If those are R strings, there are no backslashes in the first one. It has a
formfeed and a backspace in it.
I did notice that this string was special. It's a legimate R string. If
"f" and "b" are replaced by "d", it will not. My purpose is to convert a
Windows file path (eg. copied from Explorer location bar) to a R file path
through some R function inside R terminal. The "File->Change dir..." takes
a file path like "C:\Acer", but setwd function will fail. I guess there
must be some ways in R to replace a backslash by slash, eg. C:\Acer ->
C:/Acer. The first problem may be how to pass and save this kind of
strings. encodeString does not work for this, it will just ignore "\".
