Yes that is what I'm trying to do, however when I enter the code
aggregate(dstats[,c('QUOTA','L.R.QTA','L.R.A.1ST','L.R.S.
1ST','L.N.QTA','L.N.A.1ST','L.N.S.1ST','R.R.QTA','R.R.A.1ST','R.R.A.
2ND','R.R.A.3RD','R.R.S.1ST','R.R.S.2ND','R.R.S.3R','R.N.QTA','R.N.A.
1ST','R.N.A.2ND','R.N.A.3RD','R.N.S.1ST',R.N.S.2ND','R.N.S.
3RD','T.SUCCESS','T.SURPLUS')],list(dstats$Year,dstats$HD),FUN=sum)
I'm getting an error message saying:
Error: unexpected string constant in
"aggregate(dstats[,c('QUOTA','L.R.QTA','L.R.A.1ST','L.R.S.
1ST','L.N.QTA','L.N.A.1ST','L.N.S.1ST','R.R.QTA','R.R.A.1ST','R.R.A.
2ND','R.R.A.3RD','R.R.S.1ST','R.R.S.2ND','R.R.S.3R','R.N.QTA','R.N."
Any suggestions on how to fix this?
Yes. Don't mix single and double quotes.
