Hello R users, I have a string, for example: x <- "\t\tabc\t def" This string can contain any number of tabulations. I want to replace each tabulation of the begining of the string by the same number of space: " abc\t def" I'm trying to do this with gsub :
gsub("\t", " ", x) # replace every \t
[1] " abc def"
sub("^\t", " ", x) # replace only the first \t
[1] " \tabc\t def"
sub("^\t*", " ", x) # replace all beginning \t, but only one space
[1] " abc\t def" How can I do this ?
there may be better solutions, but this should do:
strings = c('pure', '\t<- 1 removed', '\t\t<- 2 removed, 1 left ->\t')
gsub('\t|(*COMMIT)(*FAIL)', ' ', strings, perl=TRUE)
# "pure" " <- 1 removed" " <- 2 removed, 1 left ->\t"
