如何升级 RStudio 版本？

Question

Recently I've tried to install keras package in R. I ran the following commands: install.packages("keras") library(keras)

But when I ran is_keras_avalable() I got FALSE.

I was told, that the problem with unsuccessful 'keras' installation may come from the old RStudio version, which is installed on my notebook (I work in RStudio 3.4.0). I was adviced to reinstall RStudio and to get a brand new version.

Could you, please, tell me how to do it? I'd be very pleased if you provide me with the necessary links for installing the latest RStudio version on Windows 8.1.

Thank you for your help.

RStudio is an application (specifically, an Integrated Development Environment, or IDE). This is a common tool for using R, which is a computer language. Much like Microsoft Word is a common tool for writing documents in English (or other languages - and in fact you can use RStudio to write files other languages like RMarkdown, Python, SQL, French, or Swahili.). However, just like you can write English in programs other than Word, you can also write and run R code in programs other than RStudio.

You can find the most recent version on the RStudio website , or you can look in the Help menu and select "Check for updates", which will give you a download link if a newer version is available.

Given the version number you show, 3.4.0, you need to upgrade R (the language), not RStudio (the application). The current RStudio version as I write this is 1.3.*, while the current R version is 4.0.*.

The place you need to go to update R is CRAN - their website has download links for Windows, Mac, and Linux.
