How to install RMySQL package for Windows?

Question

Since binary file of RMySQL package is not available, I am not able to install it on Windows.

I looked up internet. I found this link. http://www.ahschulz.de/2013/07/23/installing-rmysql-under-windows/comment-page-1/#comment-3123

I followed the instructions, but I am getting an ERROR.

This is the final output I get after

>install.packages('RMySQL',type='source')

Answer 1

• Go to System->Advanced->Enviroment Variables, press New and Enter Variable name as MYSQL_HOME and Variable values as C:/Program Files/MySQL/MySQL Server 5.6/ , and notice that it is "/" not "\\"
• Copy C:/Program Files/MySQL/MySQL Server 5.6/lib/libmysql.dll to C:/Program Files/MySQL/MySQL Server 5.6/bin and create C:/Program Files/MySQL/MySQL Server 5.6/lib/opt folder and copy C:/Program Files/MySQL/MySQL Server 5.6/lib/libmysql.lib to the opt folder
• Run install.packages('RMySQL',type='source')

In some instances you might need to restart your PC.

Answer 2

Please following the instruction here: http://biostat.mc.vanderbilt.edu/wiki/Main/RMySQL I believe you missed the step 3

3. Edit or create the file Renviron.site and add the variable MYSQL_HOME which contains the location of your MySQL install. The file typically isn't created when installing R, so you may need to create it yourself. You will want to place it under the /etc directory in your R Home area. If you don't know where that is, you can issue R.home() at your R prompt. You will be adding a variable named MYSQL_HOME in variable=value syntax.

Here's an example:

Location of Renviron.site: C:/PROGRA~1/R/R-2.11~1.0/etc/Renviron.site 
Content is: MYSQL_HOME=C:/PROGRA~1/MySQL/MYSQLS~1.0/

Answer 3

I had this same issue as well. It took me a while to understand:

1. that I needed to manually create a text file named Renviron.site in the proper Windows directory, and,

2. that the manually created Renviron.site file needed to contain the definition of the MYSQL_HOME variable.

Here is my example from Windows 10 and R version 3.2.2:

1. I issued the command R.home() at the R prompt in R Studio:

    R.home() [1] "C:/PROGRA~1/R/R-32~1.2" 

2. With that information, I navigated to the etc folder in Windows:

     C:\\Program Files\\R\\R-3.2.2\\etc 

3. I placed a manually created text file called Renviron.site within this directory (the "etc" folder). The only data in the Renviron.site text file is the following:

    MYSQL_HOME=C:/PROGRA~1/MySQL/MYSQLS~1.2/ 

   (I wasn't sure whether to use ~1.0 or ~1.2 here based on the output from the R.home() command in R, but, this seemed to work)

4. Once the file was saved, I restarted R and I was able to install the RMySQL package in R.
