First letter to upper case

Question

Is there a other version to make the first letter of each string capital and also with FALSE for flac perl?

name<-"hallo" gsub("(^[[:alpha:]])", "\\U\\1", name, perl=TRUE) 

Answer 1

You can try something like:

name<-"hallo" paste(toupper(substr(name, 1, 1)), substr(name, 2, nchar(name)), sep="") 

Or another way is to have a function like:

firstup <- function(x) {   substr(x, 1, 1) <- toupper(substr(x, 1, 1))   x } 

Examples:

firstup("abcd") ## [1] Abcd  firstup(c("hello", "world")) ## [1] "Hello" "World" 

Answer 2

As pointed out in the comment, it is now possible to do: stringr::str_to_title("iwejofwe asdFf FFFF")

stringr uses stringi under the hood which takes care of complex internationalization, unicode, etc., you can do: stri_trans_totitle("kaCk, DSJAIDO, Sasdd.", opts_brkiter = stri_opts_brkiter(type = "sentence"))

There is a C or C++ library underneath stringi.
