Changing R studio to default 32-bit R

To use the RODBC package you need to run 32-bit R. In Rstudio it is relatively easy to set it up to default to 32-bit (in my experience I have yet to need 64-bit R).

To set 32-bet default, open R studio and go to tools and select options...

This will open a new window from which you can select R version and press the Change... button

This will bring up a window where you can selected default 32-bit R

Press OK to use 32-bit. You will have to restart Rstudio to get the changes to take effect.
