greetings!!
source("https://bioconductor.org/biocLite.R")
Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) :
InternetOpenUrl failed: 'A connection with the server could not be established'
how to debug the error. when i have already many times used the bioconductor packages.
The same command is working for me the moment I write this, so the problem is on your side, and not with the Bioconductor servers. So check again, check whether you can browse the internet at all, restart your PC, etc....
Does the link open in a browser? Experiment with different values for download.file argument 'method', e.g.,
options(download.file.method="libcurl")
.
