Dear List In a package I want to import the mApply function from the Hmisc package, and I would like to import only that function. 1) If I write "Depends: Hmisc" in the DESCRIPTION file I get the whole Hmisc package, so that is not the way to go ahead. 2) According to "Writing R extensions", sec 1.6.1 "Specifying imports and exports" I can (as I read it) simply type Hmisc:::mApply(....) in my code. That works, but gives a warning in the check: * checking for unstated dependencies in R code ... WARNING '::' or ':::' imports not declared from: Hmisc 3) According to the same section I can (again as I read it) write in the NAMESPACE file importFrom(Hmisc,mApply) Then I get: * checking package dependencies ... ERROR Namespace dependencies not required: Hmisc That message goes away if I write "Depends: Hmisc" in DESCRIPTION, but then we are back to 1) where I started where the whole Hmisc package is loaded. Obviously I have missed a point or two somewhere. Can anyone enlighten me? I use R 2.5.1 on windows XP. Regards Søren
