Hi, im trying to install forecast package but i get this error. I've try some solution but it's cant hel me. Anyone ? Thankyou so much. Really need it fast.
This seems like a connectivity issue, R is not being able to connect to the CRAN repository you have selected, these are some things to try.
Choose a different CRAN repository, RStudios repository is a good choice (http://cran.rstudio.com/) or you could choose one that is geographically closer to you.
Check if your internet connection has traffic restrictions of some kind, like a firewall, proxy server, etc. This is usually the case when you are at work or school.
Also, you are using a very old version of R, this is going to bring you many installation problems, I strongly recommend you to update R to the latest version (3.6.3).
