Use this workspace to take notes, store code snippets, and build your own interactive cheatsheet!

# Import any packages you want to use here
vec.test <- c("alphabet", "betabet", "saskia")
grepl(pattern = "^a", x = vec.test)
### "^a" indicates the first letter is an "a" #####
grepl(pattern = "a$", x = vec.test)
### "a$" indicates the last letter is an "a" ####

### grep itself gives the indices of the position of the words in the vector where the pattern occurs ###
grep(pattern = "a", x = vec.test)
