Hello @mkuehn10! Thanks for finding this typo and sending in a PR. Would you mind building the package documentation such that the fix will propagate to the manual pages? that would be great!

Yes I can work on that. I also noticed there was no description of n_lowersp or n_capsp in the count documentation either (or in any other documentation). I then investigated how those were created and I assume the p means percentage. I saw the code as:

o$n_capsp <- (o$n_caps + 1L) / (o$n_chars + 1L) I understand why adding 1 to the denominator would make sense, but why add 1 to the numerator here. If there were 0 capital letters then we would want this to be 0. Is this for doing some type of ratio comparison at a later time?
