Namespace dependencies not required error although I've used Imports in DESCRIPTION

Question

I received the following error when running R CMD check:

Namespace dependencies not required: 'foreach' 'ggplot2' 'magrittr'

I've found a previous question and follow the answer there by making sure that the packages are included in the Imports field of my DESCRIPTION file, but I still received the error.

Here is my DESCRIPTION file

Type: Package Title: mytitle Version: 0.0.0.9000 Authors@R: c( person("John", "Doe", email = "[email protected]", role = c("aut", "cre")), ) Description: More about what it does (maybe more than one line) Use four spaces when indenting paragraphs within the Description. License: What license is it under? Encoding: UTF-8 LazyData: true Depends: R (>= 3.1) Imports: cowplot (>= 0.9.2), data.table (>= 1.11.4), doParallel (>= 1.0.11), foreach (>= 1.2.0), GA (>= 3.1.1), ggplot2 (>= 2.1.0), hydroGOF (>= 0.3.10), magrittr (>= 1.4), parallel (>= 3.5.0), Rcpp (>= 0.12.16) RoxygenNote: 6.1.0 Roxygen: list(markdown = TRUE) LinkingTo: Rcpp, RcppArmadillo Suggests: testthat

And here is my NAMESPACE file created by Roxygen:

export(myfunction) import(data.table) import(ggplot2) importFrom(Rcpp,evalCpp) importFrom(cowplot,plot_grid) importFrom(doParallel,registerDoParallel) importFrom(foreach,"%dopar%") importFrom(foreach,foreach) importFrom(hydroGOF,KGE) importFrom(hydroGOF,NSE) importFrom(hydroGOF,rmse) importFrom(hydroGOF,ssq) importFrom(magrittr,"%>%") importFrom(parallel,detectCores) importFrom(parallel,makeCluster) importFrom(parallel,stopCluster) useDynLib(mytitle, .registration = TRUE)

Can you please tell me what I missed?

What are you trying to do with them? It sounds a bit like you are really wanting to use Suggests: link — JBGruber

I need to use Imports rather than Suggests because I'm using ggplot(), %>% and foreach() in my package code. — Drumy

For some reason, when I removed Depends: R (>= 3.1) then it works. Any idea why? — Drumy

When R CMD check runs, it built a binary package .zip file on the parent folder of the package's folder, and also a folder call pkgname.check. I think the next time R CMD check runs, it may not rebuild that folder or that file, depending on whether changes have been made in the package. I deleted those file and folder and rebuild, everything works.
