3. Install the R Packages (Optional)<\/h3>\n
In RStudio, if you require a particular library, then you can go through the following instructions:<\/p>\n
- \n
- First, run RStudio.<\/span><\/li>\n
- After clicking on the packages tab, click on install. The following dialog box will appear.<\/span><\/li>\n

Updating R and RStudio<\/h2>\n
1. Updating R<\/h4>\n
Mac and Ubuntu<\/strong><\/p>\n
On Mac and Ubuntu, you need to go to the CRAN website, https:\/\/www.r-project.org\/<\/em> to install the newer package installer.<\/span><\/p>\n
Windows<\/strong><\/p>\n
A package called\u00a0<\/span>installr<\/a>, which is only for Windows can be used to ease the process. Updating on windows is tricky.<\/span><\/p>\n
If you don\u2019t have installr package then first install it<\/span>:\u00a0<\/span><\/p>\n
#installing the latest installr package:\r\n\r\ninstall.packages(\u201cinstallr\u201d); library(installr) # For installing & loading installr\r\n\r\nupdateR()<\/pre>\n
After running the updateR(), R will detect if there is a new version available. If there is, it will download and install it.<\/span><\/p>\n
2. Updating RStudio<\/h4>\n
- After clicking on the packages tab, click on install. The following dialog box will appear.<\/span><\/li>\n
- First, run RStudio.<\/span><\/li>\n
- For Ubuntu with Apt-get installed, execute sudo apt-get install r-base in terminal.<\/span><\/li>\n<\/ul>\n
- Open the downloaded .pkg file and install R.<\/span><\/li>\n<\/ul>\n
- Then, install RStudio<\/span><\/li>\n
