Closes #527 Filing now for early feedback. If you're OK to add the linter here I will complete the PR by adding tests etc. Informally there are these test cases thus far: ``` writeLines(' # bad stop(paste("a", "b", "c")) warning(paste0("hey", "you")) message(paste("there", "we", "go")) stop(paste("a", "b", "c", sep="")) # good stop("a", "b", "c") paste0("a", "b", "c") stop("go to", paste("jail", "now")) stop(paste("a", "b"), "c") stop(paste("a", "b", collapse=",")) stop(paste("a", "b", sep="|")) ', tmp <- tempfile()) lintr::lint(tmp, stop_paste_linter) /tmp/RtmpGfxjfA/file38c5e31aefde27:3:1: warning: Avoid stop(paste(...)) expressions, just use stop(...).

Thanks @AshesITR; done |

Closing this -- it's not a tidyverse style issue (as of now) so it's more appropriate for a different package of add-on linters |
