Hi all, My graduate student is logging onto my macpro and running R through ESS aquamacs (with Mx ssh and then Mx ess-remote). Everything is working fine until we get to graphing. We are trying to give him the ability to look at graphics interactively. The ESS manual is not too helpful: If you

Re: [R] Example for parsing XML file?

Hi Brigid. Here are a few commands that should do what you want: bri = xmlParse(myDataFile.xml) tmp = t(xmlSApply(xmlRoot(bri), xmlAttrs))[, -1] dd = as.data.frame(tmp, stringsAsFactors = FALSE, row.names = 1:nrow(tmp)) And then you can convert the columns to whatever

Re: [R] combining xYplot with map
