Package "Imports" not loading in R development package

I am building a package in R in a windows environment using Rstudio, devtools roxygen2 and Rtools.

The package is showing no problems in R CMD CHECK. However when I try to load the package using library("mypkg"), the packages specified under Imports in DESCRIPTION are not being loaded (Loading required package: message is not there). On using pkgDepends("mypkg"), the $Depends is shown as character(0).

I have to load the required packages using library() for mypkg to function.

I am using namespace imports instead of package::function() syntax. All the required packages are there in the NAMESPACE as imports().

Why is this happening? How to solve this?

That's the correct behaviour. Imports just means that code inside your package can see the functions that you import from other packages. The other packages aren't placed on the search path like with Depends.
