I teach quantitative genetics and biometrics at the Department of Plant Breeding and Genetics, Federal University of Agricultural Makurdi, Benue-Nigeria. I used to believe I could never be completely stumped on an issue. I was dead wrong. I now know what it means to be completely stumped. I mean to be way deep in above your head.
I have been learning how to use R studio for analysis. Having learnt the basics, it got to downloading packages so I could have a proper hands on by doing some statistical analysis. I have not been able to download any package no matter how and what I have tried. My wont just connect to the repository.
Below is the warning messages I keep getting;
Based on suggestions, these are the things I have tried
-I changed mirrors. Since I am Nigeria, I tried the one in South Africa and the Algeria with out success. I then read online that one can choose any CRAN mirror any where around the would and it wont matter. So I tried USA, Canada, France, UK. It did not change the outcome.
-I went to Tools >Global options >Packages >unchecked the box for "Use secure download method for HTTP" . It still did not change the outcome.
I'd love to hear from us on how to solve this issue and get cracking with my analysis.
