exert an effect on y. At some cutoffs, x can also be trichotomized into 3
ordinal levels constituting a presumed factor (fx) influencing the level of
y at all of the different measurings (1-4). x and fx are rather stable
arcoss the 4 measurements whereas z is not. H0 is that x and fx are not
influencing the level of y (i.e. explaining any variance of y) irrespective
of (i.e. controlled for) z at any of the measurements.

graphics display problem
Hello all,
I come arcoss a problem that has to do with graphics display in my machine

This is what I did. I asked R to do multiple linear regression by:
amodel<-lm(dat[,4]~dat[,1]+dat[,2]+dat[,3])
plot(amodel)
and I got only one figure (residuals vs. the fitted; instead of several
