sentences.all is a data frame in the filehash database. It is loaded into the environment with the dbLoad statement. More precisely, it is "lazy loaded."
If I first assign which(sentences.most.predicted.rf_003_2009.12.07[i.samp] == F) to, say, iF, then evaluate sent.all[iF], the error does not occur.
I thought I solved this problem the last time it plagued me by downloading the source from CRAN instead of the binary. I did that again before attempting to reproduce the error, but this time it didn't help. I wish I could supply more information, but the error message isn't at all helpful.
I only suspect filehash because (a) it evidently hasn't be updated in a while, and (b) the lazy loading mechanism could be playing a role, even though the statement sent.all <- unlist(sentences.all)[- index.tokenless.sentences] seems to create a copy.
Can anybody suggest how I can at least identify where the error is actually occurring? I am not a programmer, have not debugging tools installed, could probably install one, but would need very detailed instructions about using it.
