- The increment to i and j in your loops are done already, so remove them.
try this to see what I mean:
for(i in seq(1,5)) { print(i) }
- Provide us with a small (not with 378 rows) example that works,
hence give us your yearly.
Try str(yearly) to see for yourself what's in there exactly.
My guess is there are factors in yearly (so your conference names are
not strings as you think they are).
See ?factor (type "?factor" in R without the quotes).
If you used something like read.csv to import your yearly from a file,
try adding as.is=TRUE there, that might also solve your problem.
