String position character replacement
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 want to replace with the character "-"
[[1]]
[1] 3 9
[[2]]
[1] 3 4
[[3]]
[1] 4 7
[[4]]
[1] 5 6 7...
