Re: [R] Is SEM package of R suitable for sem analysis
A few years ago it could have been true, but now the package has improved (especially with the bootstrap procedure). At the moment there is no argument to recommend AMOS. Of course, some software like Mplus are actually better, but very specialized (and rather expensive). This is only a personal point of view.

I use R with SEM package as my tool for sem analysis, but my teacher told me AMOS is more suitable for such analysis. Could someone help tell me whether it is true that some commercial software is better accepted in academic fields? Sorry if I should not post such topics here. -- Best Regards, Reeyarn T.

Re: [R] PCA and automatic determination of the number of components
You can also use parallel analysis using the scree.plot function of the "psy" package.

Re: [R] concordance correlation coefficient using R
You can look at the fonction icc in the package psy.

I have data which i would want to assess the degree of agreement between two assays, e.g., to evaluate reproducibility or for inter-rater reliability. I have used the Pearson product-moment correlation coefficient. It looks good ranginging between 0.90 to 0.998. Though this looks good. I am told the Concordance correlation coefficient will give a better picture of how reproducible the assay is. Does any one know how to run such a test using R? If so can you kindly provide the code, and bit of explanations to spruce it up?
