无法在Windows 8上安装RMySQL

Question

I followed the installation directions at R-Bloggers website. However once I do the install.packages('RMySQL',type='source') , I get the following error. It appears that there is some conflict with regards to the path (Windows likes backward slashes whereas here the installer is trying to look up by unix style backward slashes). Any ideas what is going wrong?

--- Error Message --- install.packages('RMySQL',type='source')

Answer 1

Just copy all the files and folders from inside lib to the bin folder.

For some strange reason the installer looks for the lib files in the bin directory.
