I got the following warning when submitting a package to CRAN that I am struggling to understand:
Warning: Installed Rcpp (0.12.12) different from Rcpp used to build dplyr (0.12.11). Here is a link to the directory with the full logs from the CRAN pretest checks: https://win-builder.r-project.org/incoming_pretest/170713_171433_noaastormevents_010/ I did not get this warning on any of the systems where I ran checks before submitting to CRAN (I ran checks on my local Mac OS X install, which is R 3.4.0, on win-builder, and on Travis using the �trusty� distribution, ubuntu 14.04.5 with R 3.4.0). Within the 00install.out file from the CRAN pretest (available in the link to the full log posted above), there is the message: Please reinstall dplyr to avoid random crashes or undefined behavior. I am curious if reinstalling dplyr on my local system should fix this, given that I did not get this warning or message on my local system, or if the warning might result from the versions of dplyr and Rcpp on the system used by the CRAN pretest? The only other example I could find through googling of someone having a similar problem is here: https://github.com/KopfLab/lans2r/blob/master/cran-comments.md. It sounds like in that case the warning may have resulted from the configuration of win-builder at the time and was not something that could be resolved by the package maintainer. The package I submitted does not have a direct dependency on Rcpp but does import dplyr and other tidyverse packages. My local system (on which I built the package I submitted to CRAN) has the latest CRAN versions of both Rcpp (0.12.11) and dplyr (0.7.1). The full source code for the package I submitted is at https://github.com/geanders/noaastormevents. I have not had this warning or a similar in past packages I�ve submitted with dependencies on dplyr. I looked through recent threads here on r-pkg-devel and could not find any related posts. Does anyone have a suggestion for what�s causing this warning on the CRAN pretest and how I can resolve it? Thanks very much in advance for any advice. [[alternative HTML version deleted]]
