Hello everyone please I have an issue with grep. I have an array of pattern which can have regular expression or not. when I grep the pattern on my corpus some of them are not found because they have regular expression. I don't know how to sove the problem. Can you help me please?
Could you please turn this into a self-contained reprex (short for reproducible example)? It will help us help you.
What to do if you run into clipboard problems
If you run into problems with access to your clipboard, you can specify an outfile for the reprex, and then copy and paste the contents into the forum.
reprex::reprex(input = "fruits_stringdist.R", outfile = "fruits_stringdist.md")
For pointers specific to the community site, check out the reprex FAQ, linked to below.
You could use
mapply to vectorized the
mapply( FUN = grepl, pattern = c("^cat", "^cat", "c.t", "c.t"), fixed = c(FALSE, TRUE, FALSE, TRUE), MoreArgs = list(x = "^cat") ) # ^cat ^cat c.t c.t # FALSE TRUE TRUE FALSE
I'd suggest writing a function to handle this for you. How that functions works depends on your data and desired output.
