R版本快速更新

使用updateR()函数: 为用户检测最新版本的r, 如果当前安装的不是最新版本，即可下载安装。

updateR()用法

updateR(fast = FALSE, browse_news, install_R, copy_packages,
  copy_Rprofile.site, keep_old_packages, update_packages, start_new_R,
  quit_R, print_R_versions = TRUE, GUI = TRUE,
  to_checkMD5sums = FALSE, keep_install_file = FALSE,
  download_dir = tempdir(), silent = FALSE, setInternet2 = TRUE,
  cran_mirror = "https://cran.rstudio.com/", ...)

updateR()会执行以下的功能：

• Check what is the latest R version. If the current installed R version is up-to-date, the function ends (and returns FALSE)
• If a newer version of R is available, the user is asked if to review the NEWS of the latest R version - in order to decide if to install the newest R or not.
• If the user wishes to - the function will download and install it. (you will need to press the "next" buttons on your own)
• Once the installation is done, you should press "any-key", and the function will proceed with copying all of your packages from your old (well, current) R installation, into your newer R installation.
• You can then erase all of the packages in your old R installation.
• After your packages are moved (and the old ones possibly erased), you will get the option to update all of your packages in the new version of R.
• You will be asked if to open the Rgui of your new R.
• Lastly - you can close the current session of your old R.
