Dear R community, I have recently discovered the package oblique.tree and I must admit that it was a nice surprise for me, since I have actually made my own version of a kind of a classifier which uses the idea of oblique splits (splits by means of hyperplanes). So I am now interested in comparing these two classifiers. But what I do not seem to understand is...

We have just put a package GPArotation on CRAN. The functions in this package perform an number of different orthogonal and oblique rotations for factor analysis, using the gradient projection algorithm described in Coen A. Bernaards and Robert I. Jennrich (2005), "Gradient Projection Algorithms and Software for Arbitrary Rotation Criteria in Factor Analysis, ", Educational and Psychological Measurement (in pr...

Hello I seem to find only two types of rotation for the factanal function in R, the Varimax and Promax, but is it possible to run a orthogonal and oblique rotations in R? Thanks in advance Rosario

Dear R-List, I have carried out a factor analysis using fa (psych) with nfactors=2, rotation="oblimin" and fm="pa". Now I have to report both pattern AND structure matrix. As I have understood R-Documentation, this can be obtained by setting the "oblique.scores" argument TRUE (structure matrix) or FALSE (pattern matrix), respectively. However both produced the same loading matrix even though my factors correlate to .65 (shouldn't this have a different effect on pattern matrix than on structure matrix?). In order to find a reproducible exa...

...as the TeX italic font when I use italic(...) in an R graphic. I found out that the R postscript(..font="ComputerModern") outputs slanted text when the R function italic(..) is used in a graphic. I think the text should use the italic font. For a quick overview of italic vs. slant vs. oblique see http://www.eyewire.com/magazine/columns/robin/italic/ A response from Brian Ripley pointed me to the src/main/devPS.c file, and I traced this behaviour to the use of the slanted/oblique afm font files, rather than the italic afm font files. Anyway, I did some homework and realised that makin...

Hi, In a discussion of factor analysis in "Using Multivariate Statistics" by Tabachnick and Fidell, two matrices are singled out as important for interpreting an exploratory factor analysis (EFA) with an oblique promax rotation. One is the "structure matrix". The structure matrix contains the correlations between variables and factors. However, these correlations may be inflated because some of the variance in a factor may not be unique to it. To address this and facilitate the interpretation of...

I came across the distinction between the name of an object and the name of the class that it belongs to in an oblique way again today, which made me question my acceptance that it would be natural for them to differ. I asked a question on SO here: http://stackoverflow.com/questions/20762559/why-is-the-name-of-an-object-type-different-from-the-name-of-the-class-it-belong I wonder if anyone on the R-Devel list ha...

Hi, I need to generate some figure using the Arial font as a requirement for PLoS. Following their guidelines, I have converted the windows font files arial.tff files to .afm using tff2afm (exec file from MikTeX), but when I try to generate a postcript file, the postcript device does not recognize the .afm files. The code I use to test the new font is the following:
