Hello Jim,
I have encountered a puzzling pattern of results using brkdn.plot():
> brkdn.plot("Duration","group_val","blck",data=dpp)
$mean
[,1] [,2] [,3] [,4]
[1,] 0.653842 0.5679849 0.477645 0.4250087
[2,] 0.653842 0.5679849 0.477645 0.4250087
[3,] 0.653842 0.5679849 0.477645 0.4250087
[4,] 0.653842 0.5679849 0.477645 0.4250087
[5,] 0.653842 0.5679849 0.477645 0.4250087
(I've omitted the $std.error matrix to save space since the pattern is the
same)
To verify the pattern of repetitions is not in my data I made another
calculation and there is no pattern of repetition:
> with(dpp, ftable(by(Duration,list(group_val,blck),mean,na.rm=T)))
1 2 3 4
0.015 0.7493519 0.5125178 0.4538040 0.3498578
0.02 0.5583320 0.6234520 0.5014860 0.5001596
0.028 0.5446862 0.3600077 0.2951988 0.2842502
0.035 0.4396780 0.2335916 0.1992378 0.1661076
0.045 0.2711094 0.1305614 0.0969594 0.1491294
Is there a way to make brkdn.plot() to present this data?
Thank you,
dror
