ggplot2::plot type commands.
devtools::check()’d my R package under various scenarios without some kind of W, N or error. I cannot determine how to treat “mtcars”.
According to Hadley, I should put sysdata.rda in /data-raw folder after executing
devtools::use_data(mtcars, internal = TRUE). In addition, he says that sysdata.rda need not be documented. There is a serious
The following is abridged output. I have underlined

Given Hadley’s comments, I am disturbed by the fact that I received multiple warnings about “mtcars”.
