[PATCH 0/3] ocfs2: Inode Allocation Strategy Improvement.v2
Changelog from V1 to V2:
1. Modify some codes according to Mark's advice.
2. Attach some test statistics in the commit log of patch 3 and in
this e-mail also. See below.

Is there a way of producing an ANOVA table split into contrasts, thus showing the contrasts sums of squares and associated p-values?

Fluctuating asymmetry and measurement error

Has anyone tested for FA in R? I need to seperate out the variance due to measurement error from variation between individuals (following Palmer & Strobeck 1986).

this interpretation correct?

How to select a subset data to do a barplot in ggplot2

p<-ggplot(data,aes(x=FID));
p+geom_bar(aes(x=factor(FID),y=..count..,fill=STATUS))
But how could I exclude "nosperm" or other levels just in the use of
ggplot2 without generating another dataframe
Thanks a lot
