How long does it generally take to install caret package in R? I ran install.packages('caret', dependencies = TRUE), and R has been running the install for close to an hour now. Is this normal?
回答1:
It shouldn't take that long, I actually had to install the Caret package on one of my machines earlier today and it took less than a minute. Sounds like you might want to check your connection speed.
回答2:
With dependencies, it can take a while, mine took about 30mins and my download speed was around 18Mbps max, it had 648 dependencies as of Nov19. With-out dependencies, it is fast, as the answer from the_SJC suggests.
