建筑r包

Question

我最近为我的在线课程建立了和R软件包。但是，当我运行travis-ci build时，由于以下错误，它会停止运行：

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.

如果你能给我一些关于如何通过这次考试的提示，我将不胜感激。我还对我的包执行R检查，唯一收到的警告如下：

WARNING
  'qpdf' is needed for checks on size reduction of PDFs

然而，这种签入也停止了。

我认为\code{\link[dplyr:filter]}应该是\code{\link[dplyr]{filter}}，见https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Cross_002dreferences。那应该是(?)解决你的一些问题，不知道它是否能解决所有的问题。
