Install RMySQL in windows?

Question

I followed the instructions from the blog post Installing RMySQL under Windows. The package seems to install, but actually fails.

Output from the installation:

* installing *source* package 'RMySQL' ...
** package 'RMySQL' successfully unpacked and MD5 sums checked
checking for $MYSQL_HOME... C:/Program Files (x86)/MySQL/mysql-5.6.21-winx64/mysql-5.6.21-winx64

The downloaded source packages are in

But when I try to use the library, I get the following error:

library(RMySQL)
Error in library(RMySQL) : there is no package called ‘RMySQL’

How can I correctly install RMySQL?

Answer 1

I would use RStudio, which has a windows installer. From there you can just run:

install.packages('RMySQL')

I am not sure what it is about RStudio but it seems to integrate well with the RMySQL package
