Although Ubuntu and the Mac OS are represented on my home network, my primary system is Windows based. When running on Windows, the R Gui will choke on directional quote characters; so if you copy an R Script out of HTML and try to use it, the script may throw a series of error messages. Rather than fix them all by hand, I wrote a small utility that will automagically change all of the “ and ” characters to the quote character that R requires when running on Windows.
Picture’s worth a thousand words . . . . see the way the funny characters in the red ovals are transformed. Click to enlarge.
