Error in FUN(X[[i]], ...) : Invalid comparison operator in dependency: >=

[Julian Karch]

My appveyor build fails even though building on travis, my machine and winbuilder is succesful.

I added appveyor support to my package using

devtools::use_appveyor()

This created appveyor.yml

The build on appveyor fails with the following error

package 'remotes' successfully unpacked and MD5 sums checked
The downloaded binary packages are in
	C:\Users\appveyor\AppData\Local\Temp\1\RtmpgN24M8\downloaded_packages
+ return
+ Rscript -e 'if (!("remotes" %in% rownames(installed.packages()))) q(status=1)'
+ Rscript -e 'options(repos=c(CRAN="https://cran.rstudio.com")); remotes::install_deps(dependencies = TRUE, type="both")'

  Invalid comparison operator in dependency: >=

As far as I know, >= is a valid comparison operator for dependencies. Might have to do with the following devtools issue? r-lib/devtools#1247.

For completeness, this is the package and this the full appveyor console output.

I might be arriving a bit too late, but I wanted to drop my two cents.

I came across the same issue today. In the case of the package I was inspecting today was due to a trailing whitespace in one of the dependency lists. This is indeed related to the issue indicated above in devtools/remotes, and nothing to do with r-appveyor. The issue was easily avoidable by removing any trailing whitespaces.

In the case above, I think you have two trailing whitespaces just after the roxygen package spec (and one after "Suggest:".

Hey, not too late at all! Removing the trailing whitespaces indeed solved the problem. Thanks a lot for your help!
