Problem with describe display

[Raphael Rath]

Hi,

i have problems getting Ggobi plots into R. I saved an R file with Save Display Description and wanted to read the file into R using DescribeDisplay as explained in the book "Interactive and Dynamic Graphics for Data Analysis"

 (I brushed some points in different colors before saving the file). Then i get the following error:

Error in (function (red, green, blue, alpha, names = NULL, maxColorValue = 1)  : 

  Farbintensität 1.29372 nicht in [0, 1]

(the second line translates: Color intensity 1.29372 not in [0,1]

Thank you

Raphael,

Can you send me the GGobi saved plot file? I hopefully can work out what is wrong.

cheers,
Di

Raphael,

This was a gorgeous problem! The error occurred because ggobi saved numbers replacing decimal points “.” with the European standard “,”, and then also comma delimited the numbers. DescribeDisplay was quite confused! I manually change the commas into periods, to get valid values for the colors and the breaks, and then it all worked. The new ggobi output is attached. Is there any way for your computer to be told to use “.” instead of “,” for decimal places??

cheers,
Di
