unable to install vignettes

[FrHi94]

Hi,

I would love to use your package for sub-sampling my sequencing data! Unfortunately, I have issues downloading the package with vignettes=TRUE. I checked earlier issues but the error message I get is different from the one's who also had issues with the installation!

I had no issues with all steps before installing subseq and the vignettes but when I try to execute the installation I get the following:

I hope you can help me out here! Thank you!
