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 8 9 [[5]] [1] 2 5 7 12 I would like to get [1] "he-lohow-reyoudoing" [2] "im--odhowareyou" [3] "goo-an-you" [4] "yesi-----ijusttoldyou" [5] "o-ye-t-atsr-ght" Is there an easy way to do this? Or would the easiest way be writing a function to take substrings of the original vector and pasting in the replacement character? Thanks in advance!
