Error in file(file, ifelse(append, "a", "w")) : invalid 'open' argument

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.

Hi,
For years I've been writing text to the beginning of files with cat(append=F) ,
then following that text with data written by write.table(append=T). It is now
giving me an error message. I'm using R-3.1.2. What gives?
df <- data.frame(x = 1, y = 1:10, z = 10:1)
cat(file="junk.txt", sep=
5 matches
