[R] strange QQ-Plot

[Fred Jopp]

Hi,

i am working on a data set with EDA. That includes QQ-Plots of
residuals vs expected normal distribution. 
What puzzles me is that the range of ordinate and abscissae is
so different: while the theoretical quantiles range from [-2, 2] 
the sample quantiles on the ordinate do extent from [-20, 50]. 
Quite obviously some kind of transformation is done. 

Although i intensively RTFM i could not find, what is done here. 
What exactly characterizes the range of the ordinate in QQ-Plots ?

cheers,
Fred
