my understanding is that this behavior is known (the help file
mentions something along these lines in the example).
i'd use something like:
theText <- "a,,b,"
theText <- gsub("\\,$", ", ", theText)
and then use strsplit() on "theText"
b

I have a comma-separated data file in which trailing commas
sometimes occur.
I am using strsplit to extract the data from this file, and it seems
great
except in cases with trailing comma characters.
The example below illustrates. What I'd like is to get a fourth
element in
the answer, being an empty string just like the second element. Is
there a
way I can express my patter (or perhaps specify perl or extended) to
get
that?
strsplit("a,,b,", ",")[[1]]
[1] "a" "" "b"
