Bidimensional matrix factorization
R code to perform factorization and dimension reduction of bidimensionally linked data matrices [1]. The file BIDIFAC.R gives functions to perform the BIDIFAC factorization, simulate data, and perform missing value imputation using BIDIFAC. See BIDIFAC_example.R for example usage.

The functions bidifac.plus.R, bidifac.plus.impute.R, and bidifac.plus.given.R perform the BIDIFAC+ method, described in [2]. See bidifac.plus_example.R for example usage.
