...ights computed as the number of observations in the sample drawn from that group divided by the number of observations in the population in the group.

...sis e.g. in SPSS it is possible to save scores from the factors. Is it analogously possible to "save" the implied scores from the latent variables in a measurement model or structural model e.g. using the sem or lavaan packages, to use in further analyses?

Hi, Is it possible to assign a separate colour for comments written with #, eg:- #this is a comment . I am looking to colour them differently from the program text in R-Editor (not console). Is it possible to do so? Eg. In Visual basic, the colour for remarks gets green automatically Regards Sumit [[alternative HTML version deleted]]

Dear list members I would like to apply a vector of labels v=c("lab1","lab2","lab3") to a dataframe df=data.frame(1:3,1:3,1:3) using some kind of loop or apply function. Any ideas? Thanks Steve Powell Checked by AVG Free Edition. 17:03 [[alternative HTML version deleted]]

...n samples of students were drawn randomly from lists of students at each school, so that more students were chosen from the larger schools: 20, 30 and 40 from each of the smaller, medium and large schools. So we have (20+30+40)*3 students per cell, for 10 cells = 2700 students in this country. www.promente.org | skype stevepowell99 | Thailand +66 8 4438 2667 [[alternative HTML version deleted]]

For psychologists like me (possibly for others) by far the most time-consuming detail is variable labels. I need them for just about every analysis I do. We can use special packages like Hmisc and its function spss.get to import the labels, but then nearly all the other packages don't respect the labels, even simple things like list. So I find myself either adding them back in at every step or

Dear all, I can't get the labels slot in ICLUST to accept a character vector. library(psych) test.data <- Harman74.cor$cov ic.out <- ICLUST(test.data,nclusters =4,labels=letters[1:ncol(test.data)]) ##?Error in !labels : invalid argument type ic.out <- ICLUST(test.data,nclusters =4,labels=1:ncol(test.data)) ## OK Any ideas?
