install RMySQL on windows - r

Question

I am trying to install the package RMYSQL on windows.
To do so i followed this tutorial : http://www.ahschulz.de/2013/07/23/installing-rmysql-under-windows/
But i am getting an error when i execute
install.packages(“RMySQL”, type = “source”)
In deed R returns me the following :
Installing package into ‘D:/Users/quentin/Documents/R/win-library/3.1’

I couldn't manage to fix this problem so if someone have an idea.

Answer 1

i tried all the steps from all the instructions i could get, but still got the same problems as you got.
I finallly solved accidently by follow this code:
install.packages('RMySQL')
instead of
install.packages(“RMySQL”, type = “source”)
I cannot explain the reason, but it truly works.

Answer 2

I solved it by installing from a .zip file not from .tar.gz.
Make sure your MYSQL_HOME environment variable is set correctly and libmysql.dll is copied to bin folder!!!
Run install.packages('RMySQL') then when the "Do you want to install from sources..." window pops up select No.
Then copy the downloaded binary packages location from console.
Go to Packages -> Install, paste the location into Package archive and click Install.
