Don t use Rstudio to update R  Rstudio IS NOT R  Rstudio is just an IDE  This answer is a summary of previous answers for different OS  For all OS it is convenient to have a look in advance what will happen with the packages you have already installed here   WINDOWS -   Open CMD Powershell as an administrator and type  R  to go into interactive mode  If this does not work  search and run RGui exe instead of writing R in the console    and then   lib path  lt - gsub                Sys getenv  R LIBS USER    install packages  installr   lib   lib path  install packages  stringr   lib path  library stringr  lib loc   lib path  library installr  lib loc   lib path  installr  updateR     MacOS -   You can use updateR package  The package is not on CRAN  so you   ll need to run the following code in Rgui   install packages  devtools   devtools  install github  AndreaCirilloAC updateR   updateR admin password    PASSWORD     Where  PASSWORD  stands for your system password   Note that it is planned to merge updateR and installR in the near future to work for both Mac and Windows   Linux -   For the moment installr is NOT available for Linux MacOS  see documentation for current version 0 20   As R is installed  you can follow these instructions  in Ubuntu  although the idea is the same in other distros  add the source  update and upgrade and install

I would recommend using the Windows package installr to accomplish this   Not only will the package update your R version  but it will also copy and update all of your packages   There is a blog on the subject here  Simply run the following commands in R Studio and follow the prompts     installing loading the package  if  require installr     install packages  installr    require installr    load   install load installr    using the package  updateR     this will start the updating process of your R installation   It will check for newer versions  and if one is available  will guide you through the decisions you d need to make

I found that for me the best permanent solution to stay up-to-date under Linux was to install the R-patched project  This will keep your R installation up-to-date  and you needn t even move your packages between installations  which is described in RyanStochastic s answer    For openSUSE  see the instructions here

For completeness  the answer is  you can t do that from within RStudio   agstudy has it right - you need to install the newer version of R  then restart RStudio and it will automagically use the new version  as  Brandon noted   It would be great if there was an update R   function  analogous to the install packages   function or the update packages function    So  in order to install R    go to http   www r-project org   click on  CRAN    then choose the CRAN site that you like  I like Kansas  http   rweb quant ku edu cran   click on  Download R for XXX   where XXX is your operating system  follow the installation procedure for your operating system restart RStudio rejoice   --wait - what about my beloved packages  --  ok  I use a Mac  so I can only provide accurate details for the Mac - perhaps someone else can provide the accurate paths for windows linux  I believe the process will be the same   To ensure that your packages work with your shiny new version of R  you need to    move the packages from the old R installation into the new version  on Mac OSX  this means moving all folders from here    Library Frameworks R framework Versions 2 15 Resources library   to here    Library Frameworks R framework Versions 3 0 Resources library    where you ll replace  2 15  and  3 0  with whatever versions you re upgrading from and to  And only copy whatever packages aren t already in the destination directory  i e  don t overwrite your new  base  package with your old one - if you did  don t worry  we ll fix it in the next step anyway  If those paths don t work for you  try using installed packages   to find the proper pathnames   now you can update your packages by typing update packages   in your RStudio console  and answering  y  to all of the prompts    gt  update packages checkBuilt TRUE  class    Version 7 3-7 installed in  Library Frameworks R framework Versions 3 0 Resources library   Version 7 3-8 available at http   cran rstudio com Update  y N c    y ---etc---  finally  to reassure yourself that you have done everything  type these two commands in the RStudio console to see what you have got    gt  version  gt  packageStatus
