I was curious about this, so I decided to do a quick character count
on the characters in the R library source. I didn't have the current
version handy, so I did it on the version 1.2.2 source, consisting of
about 1.3 million characters.
This isn't counting symbols, it's counting characters, which is a lot
And the top 10 in frequency were:
Of these, the only one that is almost certainly a symbol is the comma,
but it sure looks like whitespace is another contender!
If we restrict the counts to the single characters that are usually
symbols (in a really loose sense of "usually" and "symbols" :-), we
So assignment could well be in the top 10, but probably isn't in the
top 3. And for what it's worth, the underscore was way down at a
count of 140.
