[R] formatting column names of data frame
Is there any way to format the headers of data frames, for printing? I am using Sweave to generate formatted reports. In Sweave, I read in a data.frame: result - read.table(path.to.table); then display it: print.data.frame(result); This gives me what I expect in the eventual final output: RecordAverage Maximum 1 34 899 2 14 15 3 433 1003 ... ... ... What I am hoping to do is distinguish one or more of the column headers, for example, I want Average or Maximum to be bold, underlined, etc., just some way to make the column name stand out visually. Any idea if this is possible? Any suggestions appreciated.

Re: [R] memory profiling
Using: summaryRprof(memory=both) did the trick, thank you. I had not been using that setting when calling summaryRprof.
