sparseDecom¶

purpose:

Convenience wrapper for eigenanatomy decomposition.

description:

Decomposes a matrix into sparse eigenevectors to maximize explained variance.

usage:

sparseDecom( inmatrix=NA, inmask=NA , sparseness=0.01 , nvecs=50 , its=5 , cthresh=250 )

examples:

mat <- replicate(100, rnorm(20))

mydecom <- sparseDecom(mat)
