Re: [R] write.table with append=T after using cat on same file
This will happen if you have redefined 'T': > T <- 101:104 > write.table(df, file="junk.txt", sep=",", append=T, quote=F, row.names=F, col.names=F) Error in file(file, ifelse(append, "a", "w")) : invalid 'open' argument Use 'TRUE' and 'FALSE' instead of 'T' and 'F' this sort of problem.

Re: [R] write.table with append=T after using cat on same file
I do not get an error with R-3.2.1 on Mac OS. You may have done something prior to this code so that perhaps F is not FALSE or T is not TRUE. R.
