Hi,


I am developing a package based on the SummarizedExperiment package. I have included the 
SummarizedExperiment package in both DESCRIPTION and NAMESPACE files. In some functions of my 
package, and also in the vignette, I use the function "assays()" from the 
SummarizedExperiment package. However, when I try to build the vignette, it says: function 
"assays()" not found. The same happens when checking my package.



Imports: SummarizedExperiment

and

importFrom(SummarizedExperiment, assays)

or

import(SummarizedExperiment)

is sufficient for R functions defined in your package.

The code in a vignette is run as if it were a script source'd in to R, so if you use assays() at the 'top level' (seen by the user) then you need to ensure that assays() is visible -- include SummarizedExperiment in the Depends: field of your package and library(yourpackage) in the vignette, or library(SummarizedExperiment) in your vignette, or SummarizedExperiment::assays() in your vignette, etc.

If that doesn't help, feel free to point to the specific vignette in github.

Any idea for this ?


Thanks,


Andrea
