Warning message: In readLines(filename) : incomplete final line found on 'test.R'

[Agent-Sesame]

Getting above error message when linting a very simple chunk of code.

`runtimetool <- function(x) {

start_time <- Sys.time()
Sys.sleep(x)
end_time <- Sys.time()
time_taken <- end_time - start_time
return(time_taken)

}`

The file is missing a newline at the end of the file. If you are running RStudio you can turn on an option to ensure it always saves files with a trailing newline.

Thanks, that worked. Sorry for reporting such a minor thing~

No worries, it is a little confusing, unfortunately the error message is coming from readLines() in this case, so there isn't a lot we can do in lintr

Hello!
Have the same problem, but turning on the option didn't help(

Full message is:

Warning message:
In readLines(con <- gzfile(tmp)): incomplete final line found on 'C:\Users\User\AppData\Local\Temp\RtmpWyvSp7\file2e042d652733'

@gitmexanism I think that option only appends to files that have been modified since they were last saved. Could you add a newline and retry linting it, please.

[AraujoH]

If you use readr::read_lines(), that missing newline won'be be an issue.

Since #562 we actually catch this warning. One could create a terminal_newline_linter from this information if deemed useful?
