plot(aModel) vs. influence.measures()
A while back I asked about getting a list of points that R considers influential after fitting a linear model, and very quickly got a helpful pointer to influence.measures(). But "it has happened again." The trouble I am having is that points marked on plots are not flagged in the output from influence.measures(), and I can't read them on the plots. I tried some successive

graphics display problem
Hello all,
I come arcoss a problem that has to do with graphics display in my machine
(Redhat 7.35).
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
plots), and the following message:
Error in abline (h=0, lty=3, col="gray"):
Error: X11 cannot allocate additional graphics colors

In my app , a user can create a set of question then a table is
dynamily created , in the database,to store the answers of the
questions. the name of the table is answers_x (x is the id of the

Is it possible to dynamicly create a model, to handle the answer_x
tables ?? I can''t manually create a model then restart the server.
