Hello,
 
I am getting the following NOTES at R CMD check step:
 
NOTE1:
* checking package dependencies ... NOTE
Depends: includes the non-default packages:
  ‘MASS’ ‘parallel’ ‘S4Vectors’ ‘IRanges’ ‘GenomeInfoDb’
  ‘GenomicRanges’ ‘GenomicAlignments’ ‘rtracklayer’
Adding so many packages to the search path is excessive and importing
selectively is preferable.
 
NOTE2:
* checking re-building of vignette outputs ... NOTE
Warnings in re-building vignettes:
  Warning: file stem ‘/fig2’ is not portable
  Warning: file stem ‘/fig3’ is not portable
 
Can anyone suggest how I can fix these? Thanks in advance!
 
Best,
Anusha
