cant open libraries

[bethpay]

Bit of an R novice
I am struggling to open a number of libraries and data files. was working fine yesterday -
this is the error message

Error: package or namespace load failed for ‘GEOquery’ in dyn.load(file, DLLpath = DLLpath, ...):

Welcome in the community.
So you mean that yesterday you could work with your code
and after restarting the same machine this morning it would not work?
I assume that you did no major changes on your machine in between ?

Can you share the code you are using and the result of the statement

sessionInfo()

I did install a new package to analyse some data (PCAtools) and it would not open the data file i was trying to use. I then went back to what i was using yesterday and that would not work either.

Anyway i uninstalled and reinstalled R and Rstudio and it now works

Quite simular to power-off, power-on:
it often helps
