I'm trying to install some packages, including "ggplot2", "GEOquery", "limma", etc. Meanwhile, I keep facing either one of the errors mentioned below: (And the same errors with a different repository for "ggplot2" and "limma")

install.packages("GEOquery")

Warning in install.packages : unable to access index for repository https://bioconductor.org/packages/3.9/bioc/src/contrib: cannot open URL 'https://bioconductor.org/packages/3.9/bioc/src/contrib/PACKAGES'

Warning in install.packages : package ‘GEOquery’ is not available (for R version 3.6.0)

rinstall.packages
Can you follow the link to PACKAGES in your web browser? Can you evaluate the command read.dcf(url("https://bioconductor.org/packages/3.9/bioc/src/contrib/PACKAGES")) in R? – Martin Morgan
I could open the link in my browser. But I have the error mentioned below while trying to run your suggested command: Error in read.dcf(url("https://bioconductor.org/packages/3.9/bioc/src/contrib/PACKAGES")) : cannot open the connection In addition: Warning message: In read.dcf(url("https://bioconductor.org/packages/3.9/bioc/src/contrib/PACKAGES")) : InternetOpenUrl failed: 'P¼' @MartinMorgan – pedram
