Rd warnings

[IndrajeetPatil]

When I download ggplot2, it produces the following .Rd warnings. From user's point-of-view, this is not at all important. But I am trying to get to the source of why such warnings are generated in the first place and what can be changed in the roxygen2 skeleton to get rid of such warnings.

Rd warning: C:/Users/inp099/AppData/Local/Temp/RtmpIL6A2X/R.INSTALL1f709765163/ggplot2/man/tidyeval.Rd:23: file link 'syms' in package 'rlang' does not exist and so has been treated as a topic

I think this just requires a bump in the required version of rlang in DESCRIPTION

I don't think updating rlang will help, this seems a roxygen2's problem to me, if you think this is actually a problem. The warnings come from here in src/library/tools/R/Rd2HTML.R; it seems R doesn't feel comfortable with the form of \link[pkg]{topic} and prefers these forms with the file specified:

 ## ----------------- \link[pkg]{file} and \link[pkg:file]{bar}

(I see this warnings too many times here and there so I don't even think this is actually a warning... Thanks for the chance to dig into the R's source code... :P)

[IndrajeetPatil]

Whoa! Thanks @yutannihilation for digging into the code to figure this one out. I have been getting similar warnings and thought this issue was specific to the pipe operator (r-lib/usethis#478), but this seems to be a much general issue with roxygen2.

[yutannihilation]

Oh, curious, it seems not everyone sees this warning. Anyway, I don't think ggplot2's repo is the right place to discuss. Maybe this issue is?

r-lib/roxygen2#707
