[rkward-devel] New plugin and functions

[Prasenjit Kapat]

Hi,

I haven't looked at the plugins but I looked at the pdf file; it is surely 
promising. Just a quick comment: since you are using lm, may be it is worth 
writing a full blown plugin for lm itself with the plotting options may be. 
Is that what you have already done (may be I didn't catch you correctly)? 

At the same time, I am just thinking out loud: Is there any copyright issues 
of making a plot "look" like that of Minitab? I wouldn't think so, but we 
should be careful nonetheless. Precaution is better than cure :)

Regards
PK
