Oh cool! I didn't realize you could assign a different value to a substring
like that.
Thanks!

Try this:
sapply(mapply(replace, x = strsplit(avec, NULL), list = alist, MoreArgs =
list(values = "-")), paste, collapse = "")

And here's an alternative solution:
subchar <- function(string, pos, char="-") {
for(i in pos) {
string <- gsub(paste("^(.{&q

And here's an alternative solution:
subchar <- function(string, pos, char="-") {
for(i in pos) {
string <- gsub(paste("^(.{", i-1, "}).", sep=""), "\\1-", string)
}
string

Hi Joy,
Perhaps not the easiest way, but the following seems to work:
x <- c("hellohowareyoudoing", "imgoodhowareyou", "goodandyou",
"yesimgoodijusttoldyou", "ohyesthatsright")
pos <- list(c(3, 9), c(3,4), c(4,7), 5:9, c(2, 5, 7, 12))
sapply(1:length(pos), function(i){
xx <- strsplit(x, "")[
Hi,
Is there a way to efficiently replace specified indices in a string with
another character? For example, if I had a vector of strings such as
[1] "hellohowareyoudoing"
[2] "imgoodhowareyou"
[3] "goodandyou"
[4] "yesimgoodijusttoldyou"
[5] "ohyesthatsright"
and had a list of positions that I
8 matches
