I want to search for anything that begins with 55 and anything that has the word Roof (case-sensitive, for those who are curious) in it.
So far I have been unsuccessful, as I can only seem to use the OR operator:
grepl("*^55|*Roof", dataset$longname)
Ultimately, I want to achieve something like this:
grepl("*^55&&*Roof", dataset$longname)
or
grepl("*^55&*Roof", dataset$longname)
(Clearly, neither of these work - they're for illustration only.)
I want my results to show anything that begins with 55 and which has the word Roof anywhere in it.
For example, I would expect both of these results to be picked up by the grepl() function:
55 - Roof Structure
and
55-Wall to Roof
Is there an AND operator that can be used with grepl()?
