Having problems installing dslabs package

General
#1

Hello Friends,

I am having problems installing dslabs and some other packages in rstudio

For example, I keep getting this error messages all the time:

install.packages(dslabs)
Error in install.packages : object 'dslabs' not found

I have tried several ways but not installing. Please i need assistance.

Thanks.

You have to quote the package name, otherwise is going to be interpreted as a variable that doesn't exist.

install.packages("dslabs")

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.

  • Disable secure download setting.

  • 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.

I actually tried this and as at now I'm at loss on what to do. Maybe I'll save up and get a new system and try again on it. I guess it's because this one is pretty old. Thank you though. I really appreciate.

Thanks. I tried it. It brought out this:

package ‘dslabs’ is available as a source package but not as a binary

Warning in install.packages :

You are using a very old R version, this is going to bring you many installation issues, it would be better for you if you update it to the latest version 3.6.3
