Hi:

It's not hard to roll your own here. For first character capitalization,

mycap <- function(str) {
  x <- substring(toupper(str), 1, 1)
  y <- substring(tolower(str), 2, nchar(str))
  paste(x, y, sep = '')
 }

It's not especially fast but it works if the objective is to capitalize only
the first letter of a word.

# Applying this to the best actor in one of my favorite films, Little Big
Man
# (first one I thought of with three names :)
u <- c('cHieF', 'DaN', 'GeORgE')
mycap(u)
[1] "Chief"  "Dan"    "George"

and on your counties,
with(correlfile, mycap(county))
[1] "Autauga" "Baldwin" "Barbour"

CapLeading on my actor name vector:
library(cwhmisc)
CapLeading(u)
[1] "CHieF"  "DaN"    "GeORgE"

If you look carefully, the function capitalizes the first letter but leaves
the others as is. I suspect that's not what you expected.

HTH,
Dennis
