problem with mass package/control+enter

Hi, I don't know what the real problem with RStudio is, I try to explain my issue: at any moment while I have to do an histogram of a dataset, typing control+enter for run the comand, appears the advice (that I enclose here), it opens in a new window the "guideline of mass package" that I use in previous step to exploit the "fitdistr" command. I try to delete mass and download it again, restart the R session but all as before when I run the command.

Let me know, and excuse me for my english (IT)

Hi, welcome!

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

I think you should start a fresh R session,
and only do


if there are errors - then please list the text for them in full here (rather than screenshot) and we can try to understand the problem.

if there are no errors - try and run your script/ do your work, in the hope that MASS no longer needs an update to work.
