[...] It seems to me that what you are looking for, is some sort of structured equation models (à la Lisrel). The pls package implements partial least squares regression and principal component regression, which is something different. I quess you could still use plsr for the "outer model" (path model), but you would have to build the "inner model" (the constructs) with other tools, such as prcomp/princomp or other factor analyses (see e.g. ?factanal and ?varimax). Alternatively, there is an R package "sem" that implements structured equation models. You might want to take a look at that. -- Bjørn-Helge Mevik ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
