Bioconductor not re-installing

Question

[theaspirant]

Hello everyone,

I am new to this area, I installed R some days back and then Bioconductor package, at the time of installing many other software got installed and I updated all of them. Some how I uninstall R and reinstall it again today. After that I tried to install Bioconductor.

Error message coming like this

[Previously saved workspace restored]

I want to ask that does Bioconductor is already installed in newly installed R or some thing else ? As I can see limma in the list of which I installed earlier. Please make me clear

Thanks in advance

Please check your internet connection.

Earlier I was trying all these with LAN internet connection (manual proxy setting) and installed R, no problem came in but problem arises when I tried to install Bioconductor. For no reason I changed manual proxy setting to auto detecting proxy setting and to surprise (at least for me) it worked I could install bioconductor !

I also thought the same way. But internet connection is there I am doing other work on internet. But error shows no internet connectivity

Have you tried using

source("http://bioconductor.org/biocLite.R")

instead of

source("https://bioconductor.org/biocLite.R") ?

Some networks or setups don't like https for some reason.

I tried both. didn't work. I changed the proxy setting of my internet connection.!
