I want to uninstall *Bioconductor* [affycoretools package](https://www.bioconductor.org/packages/release/bioc/html/affycoretools.html) and reinstall it, who can help me?
Go to the **Packages** in right bottom corner of Rstudio, sear the package name and click on the adjacent **X** icon to remove it.
