That is pretty neat! I did not know about that. I will have to look into that further. So I take it you just want to get x,y points and pass them to R for your analysis. Perhaps that will be all you will need and not the Hough data.rsangole wrote:Nope. R is a statistical programming language.fmw42 wrote:What is R? Ruby?

You're probably right. Wierdly... through terminal, $PATH and $MAGICK_HOME turn out OK.snibgo wrote:Re white/gray(255): perhaps IM can't find colors.xml, which should be in MAGICK_HOME.rsangole wrote:... can't figure out how to permanently change the PATH and MAGICK_HOME variables

> By default OSX GUI applications don't inherit the environment variables set in the .profile file. The easiest way to solve this is simply to invoke RStudio from the Terminal using the following command:
open -a RStudio
which will open it using the .profile settings you've configured on your machine.
