I doubt that you have a dataframe with those features, since R would
not allow such an event; more likely you have data in a file. If your
goal is to determine the number of items, then you should definitely
look at:
?count.fields
count.fields(filename, sep=",") # would give you 1 + the number
commas in each line of the file
