Hi folks, I have come across a simple quirk that took me a long time to figure out. The gist is that if I write, in the example section of an Rd file, the line
c = a %*% b what R will see when running the example is c = a since the % signs are apparently considered comment signs even in the \examples section. The change from c = a %*% b to c = a can easily make the example code fail with an error further down the line. The thing is, if you take the code and copy-paste it into a standard R session, the code will run correctly (which is what happened to me and it took me several hours to figure this mystery out). The solution is to escape the % signs by a backslash, i.e. to write c = a \%*\% b The suggestion is (of course) to make the Rd processor/parser not consider % sign a comment sign in the examples section. Hopefully that wouldn't be too difficult...
