Thanks for the answers the appear to be just right. i.e. corrmat[upper.tri(corrmat)] or x[col(x)>row(x)] The slight problem is I lose all the column & row labels from the correlation matrix, so I am...

I am trying to compose some documentation for a package I hope to release soon. However when I do the following: R CMD Rd2dvi --pdf mypackage.Rd I get two mainly blank pages prepended to the top of the document...

Thanks guys for the help, here's the final (grizzly?) solution: #generate a correlation matrix cm<-cor(someDataFrame, y = NULL ...) # get the list of labels (included in the dataframe) labels<-labels(cm)[[1]] # retrieve the uppper portion of the correlation...
