Dear Researchers,

I am facing challenging installing these packages ggplot, dplyr, likert etc in R.

It use to run on my laptop but of recent it stopped running and when I want to install it, I receive a message like there is non-zero exist status.

I have try other methods like:

update.packages(checkBuilt = TRUE)

install.packages('dplyr', dependencies = TRUE)

But the issue still persist.

I am using windows 10

I will be very grateful to receive help on how I can solve this issue.

Thank you all
