MatchesIndices(HFWutils) | R Documentation |
returns indices whether patterns were matched succesfully in a character vector
MatchesIndices(x, patt,fixed=FALSE)
x |
~~Describe x here~~ |
patt |
~~Describe patt here~~ |
fixed |
~~Describe fixed here~~ |
returns two indices one correspoding to the character vector, abnother to the patterns
~Describe the value returned If it is a LIST, use
