[R] Pattern match

[Christofer Bogaso]

Hello again, in the help page of grep() function, it is written that

pattern:

 character string containing a regular expression (or character string
for fixed = TRUE) to be matched in the given character vector. Coerced
by as.character to a character string if possible. If a character
vector of length 2 or more is supplied, the first element is used with
a warning. Missing values are allowed except for regexpr and gregexpr.

But I have a vetcor of length '(> 1)' for the pattern match, and I
need to have approximate match.

Is there any function similar to grep() to handle that?

Thanks for your help.
