David, Yes, the csv file separator is the pipe.
It is _not_ a csv file. You need to use read.table with sep = "|".
I think you need to go back and do your input operations again with sep="|" (Or you could provide str() on the data.frame rather than making us guess.)
str(chemdata)
'data.frame': 14886 obs. of 1 variable: $ site_id.sample_date.param.quant: Factor w/ 14886 levels "BC-0.5|1996-04-19|Arsenic|0.01",..: 11579 14219 13298 11982 11909 13371 13082 111 12 23 ... Thanks, Rich
