R help - Jul 2012 - Sparse Logistic PCA package?

Hi UseRs,

Has anyone come across an R package (or any other software) that can
implement Sparse Logistic PCA (an extension to Sparse PCA that works in the
presence of binary-type data)?

Specifically, I have read the 2010 paper by Lee et al. called "Sparse
Logistic Principal Component Analysis for Binary Data".

Thanks,

Ash
