Hi Folks, This is a totally off-topic diversion that I thought people might find fun.
I've been working on a small parser framework that I'm integrating into Obversive to provide code analysis of R scripts and stuff. It is still a work in progress, but the parser currently can parse R code and produce an XML output file representing the Abstract Syntax Tree. I thought it would be kind of fun to take the results and throw the XML into Exist (an XML database) so that you can search the structure of an R script. I have a sample up at my site at: http://www.zedshaw.com:8888/simple/xquery.xsp Where you can search for things in a chunk of the R test suite using the XPath and XQuery syntax. So, you can search for all function calls inside of for loops with: //FOR//CALL, or find all calls to c() with //[EMAIL PROTECTED]"c"]. Have fun with it. It's nothing serious, but I may turn it into a code comprehension tool later down the line.
