You probably have mismatched quotes. Consider using quote="". Also
consider doing this:
table(count.fields(file-name)) # with a valid file name
That count.fields function is very useful since it accepts the same
arguments as the read.tables functions, with defaults of:
quote = "\"'", skip = 0, blank.lines.skip = TRUE, comment.char = "#")
