It seems that the R session used by 'check' doesn't look in the library used by
your interactive session. This discrepancy may happen since the check tools do
not load the same Renviron files as interactive sessions. This may result in
different libraries in interactive and 'check' sessions. See ?Startup,
especially section Note.
It is difficult to give more specific advice without details of your setup.
Hope this helps,

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.
