You should be able to get what you want using the dcast function (I think).
test.melted <- melt(tds.anal)

Dan,
I don't think the data frame melted properly. I tried the dcast() but
sampdate is not found:
c.tds.anal <- dcast(m.tds.anal, site + sampdate ~ param)
Error in eval(expr, envir, enclos) : object 'sampdate' not found
Perhaps I still need to better understand the parameters in the melt()
function.
