Damian Betebenner a �crit :
Hello,
Does anyone know of a "slick" way to get R to convert a string which
is all upper case to a string where the first letter in each word is
upper case and all others are lower case?
I suspect the solution is to begin by parsing the string, convert the
appropriate letters to upper and lower case using "toupper" and
"tolower", and then to paste the pieces back together. Moreover,
given the elegance and power of R, I'll bet this can be coded very
tersely. Before I embarked on trying to code this, I thought I would
tap the R braintrust to see if this has already been done.
Any help greatly appreciated,
Damian

This question was posted a while ago and answered by Christian
Hoffmann. I wrapped it in a small function:
CapLeading <- function (string){
fn <- function(x){
v <- unlist(strsplit(x, split = " "))
u <- sapply(v, function(x){
x <- tolower(x)
substring(x, 1, 1) <- toupper(substring(x, 1, 1))
x})
paste(u, collapse = " ")
}
sapply(string, fn)
}
Best,
Renaud
