I would suggest that unlist(lapply(... should always be preferable to
sapply(lapply... if you want to convert data in a data frame to a
vector. I can't see any reason to run the same loop twice. But check
timings -- maybe I'm overly sensitive to unimportant aesthetics.
Cheers,

We can't say because we don't know how a was created.
Please email the output from
