Subject: [R-pkg-devel] Package builds, installs, and runs but does not
pass devtools::check()
Greetings. I'm working on a small package, and I'm using the devtools
functions to create, build, etc., the package.
As indicated in the subject line, I get no errors when I do:
> build()
> install()
When I run a separate R session and load the package, i.e.,
> library(my_pkg)
the package loads without error, and the two exported functions appear
to work as advertised.
OTOH, if I include devtools::check() in the construction of the
package, I consistently get an error:
* installing *source* package ?my_pkg? ...
** R
** preparing package for lazy loading
Error in loadNamespace(from, lib.loc = .library) :
there is no package called ?dplyr?
Error : unable to load R code in package 'my_pkg'
Clearly there *is* a package called "dplyr" on my system (see the
session info below, for instance). And, as I've mentioned, the code
*does* run, and I can watch it successfully reading CSV files.
Here's the relevant part of my DESCRIPTION file:
Depends: R (>= 3.4.4)
Imports: readr,
dplyr,
ggplot2,
purrr,
magrittr
I suspect the problem may be that I'm misunderstanding something about
the `import::from()` function, which I'm using for the first time to
load required functions into my code. In each of the three files that
use dplyr I have the line:
import::from(dplyr, mutate, filter, rename, select, setdiff,
slice, "%>%")
I've tried:
(1) putting that line in just one of the files (the lexically first one)
(2) including different subsets of dplyr functions, as needed, in
the various files
Needless to say, I haven't seen any improvement with any of the above
(or any of the other thrashing I've done).
If you can point me in the right direction, I'd appreciate it. Thanks.
