Hi all, Does anybody know if it is possible to build a fractional factorial design in R? That is, suppose that we want do design an experiment with 3 factors with 2, 3 and 3 levels, respectivly. However we want to consider, let's say, only 6 from all possible level combinations. Does R design such experiment? Thanks in advance, Caio [[alternative HTML version deleted]]

Hi all, How could I draw a plot with two y axes? For example, if I need too plot two curves in the same graphic, which are measured in different scales. Thanks a lot in advance, Caio [[alternative HTML version deleted]]

Hi all, Is there any package in R which fits binary regression models with a probit (or logit) link function related to a nonlinear predictor with both fixed and random effects? Something like that: Y ~ Bernoulli(p) probit(p) = h(X*Beta + Z*b), where ``h'' is a nonlinear function, X and Z are known design matrices, Beta are fixed effects and b are random effects. Thanks all in

Hi all, Is there any R package that fits binary regression models with power (generalized) logistic link function? Thanks a lot in advance, Best, Caio [[alternative HTML version deleted]]

Hi all, I have a sample of n values from a bivariate distribution (from a MCMC procedure). How could I draw a contour plot of "the joint density" based on that sample ? Sorry if I was not too clear. Thans in advance, Regards, Caio [[alternative HTML version deleted]]

Hi all, I am using the function "plotCI" with the following command: plotCI(m.residuos.p.2 [1:41],li=m.residuos.p.3 [1:41],ui=m.residuos.p.4 [1:41],lty=1,ylab="") This generates exactly what I want except for the fact that I wanna drawn a line linking the points (m.residuos). How could I do that? Thanks a lot in advance, Caio [[alternative HTML version deleted]]
