     I am trying to check for backslashes in data, then remove them when I
     find them, but am having a difficult time figuring out the best way to
     do it. I know the backslash is the escape character in R, and I
     should be able to use 'gsub' to accomplish this, but I all I seem to
     be getting are errors. For example:
     If entry is:
     "Hello\World"
     I want:
     "HelloWorld"
     There are several entries with backslashes, and I need to find them
     and delete them. All help is welcome, thank you.
