I have recently built and R package for my online course. However, when I run travis-ci build, it grounds to a halt due to the following error:
ERROR: configuration failed for package ‘gert’
* removing ‘/home/travis/R/Library/gert’
Error in i.p(...) :
(converted from warning) installation of package ‘gert’ had non-zero exit status
Calls: <Anonymous> ... with_rprofile_user -> with_envvar -> force -> force -> i.p
Execution halted
The command "Rscript -e 'deps <- remotes::dev_package_deps(dependencies = NA);remotes::install_deps(dependencies = TRUE);if (!all(deps$package %in% installed.packages())) { message("missing: ", paste(setdiff(deps$package, installed.packages()), collapse=", ")); q(status = 1, save = "no")}'" failed and exited with 1 during .
Your build has been stopped.
I would appreciate it if you could give me some hints on how to pass this test. I also run R cmd check on my package and the only warning I receive is the following:
WARNING
'qpdf' is needed for checks on size reduction of PDFs
However, this check in also halted.
I think \code{\link[dplyr:filter]} should be \code{\link[dplyr]{filter}}, see https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Cross_002dreferences . That should (?) solve some of your problems, don't know if it will solve all of them.
