If I made a scatterplotmatrix with the command show below I obtain a matrix (visible in the image) that show which variables is more correlated with dmp data (violet color).
But, if I made a linear model between the dependent variable (dmp) and many independent variables
I get different information about the significativity of...

lm.fit error in scatterplot matrix
I am getting the following error:
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
0 (non-NA) cases
when running the command
scatterplotMatrix(~THL+WL+BD+TL+Mass|SEX_,by.group=TRUE,plot.points=T,smooth=F,main=spp,)
it works fine without the "by group" option
I assume there are some cases with too few values, how can I get the loop containing this line to skip errors and move on to the next case?

Scatterplot matrix with partly transformed axis
Hi,
I am wondering if anybody has experience with
scatterplot matrices where some (but NOT all) axis
are transformed and the labels are nicely plotted.
So far I looked into
1) pairs()
2) scatterplotMatrix() from package 'car'
3) splom() from packagae 'lattice'
4) plotmatrix() from 'ggplot2'
I can see no easy way to get what I want which is:
*) a scatterplot matrix of three variables
*) 2 of 3 variables should be log-transformed
*) the labels for the log transformed variables...
