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
