Thanks for getting back to me. None of them work, because I’m trying to use
the string in the function call - myfun(z, “string”) to replace the empty
space in ggtitle.
When I call myfun(z, gsub(“______”, “string (or any word)”, myfun), I get an
error msg because gsub is looking for a data frame, not a function.
Paste or paste0 doesn’t work, either because I still have to replace the space
in ggtitle with something.
In short, I want to put another argument into the function that will enable me
to call it and fill that space.
I’m stumped.
