R-CMD-CHECK warnings & notes

🐞 Describe the bug: When running the R-CMD-CHECK (locally or on remote), the following warnings / notes are raised:

✔  creating vignettes (3m 3.7s)
   Warning in person1(given = given[[i]], family = family[[i]], middle = middle[[i]],  :
     It is recommended to use 'given' instead of 'middle'.

─  checking for empty or unneeded directories
   Removed empty directory 'mixOmics/.vscode'
   Removed empty directory 'mixOmics/R/New folder'
   Removed empty directory 'mixOmics/build'
   Removed empty directory 'mixOmics/tests/testthat/_snaps'

N  checking installed package size ... 
     installed size is  9.5Mb
     sub-directories of 1Mb or more:
       R      1.4Mb
       data   3.3Mb
       doc    3.3Mb

N  checking R code for possible problems (32.6s)
   predict.block.pls: no visible global function definition for 'setNames'
   predict.block.spls: no visible global function definition for
     'setNames'
   predict.mint.splsda: no visible global function definition for
     'setNames'
   predict.mixo_pls: no visible global function definition for 'setNames'
   predict.mixo_spls: no visible global function definition for 'setNames'
   Undefined global functions or variables:
     setNames
   Consider adding
     importFrom("stats", "setNames")
   to your NAMESPACE file.

🤔 Expected behavior: Ideally, there should be none (or very few) warnings/notes within this check
