Excluding function in import - namespace

Question

My problem is that in my imports there are two packages having the function called alpha but in my code I use only that from package ggplot2 (the other package is psychometric). After checking I got this warning:

Warning: replacing previous import by 'psychometric::alpha' when loading 'mypackage'

Description file:

Imports: deltaPlotR, difNLR, difR, foreign, ggplot2, gridExtra, ltm, moments, nnet, psychometric, reshape2, shiny, shinyAce

Namespace file:

import(shiny,
       shinyAce,
       moments,
       foreign,
       nnet,
       ggplot2,
       reshape2,
       ltm,
       psychometric,
       difR,
       deltaPlotR,
       gridExtra,
       difNLR)

While I use a lot of functions from both packages (ggplot2 and psychometric) I tried to use import(psychometric, exclude = alpha) but I got an error:

ERROR
Namespace dependency not required: 'alpha'

We could call the function with its full name : ggplot2::alpha() — zx8754

Instead of changing namespaces and imports, we can call the function explicitly:

ggplot2::alpha()
