PCA from file and project second dataset after taking log of both

Description

Reads two files with samples in columns and variables in rows. Intersect the common variables. Take log2(x+1) of both. Do PCA on file and project file2 onto this PCA. Writes to file scores, loadings, eigenvalues of original PCA. Writes to file rotated scores of the projected dataset.

Usage

intersect_log_doPCA_from_file_and_project_second_dataset(file, file2,
  train_string, center = TRUE, scale = FALSE)

Arguments

file	Filepath/filename of data matrix with no row numbering. Data file to do PCA on.
file2	Filepath/filename of data matrix with no row numbering. Data file to project.
train_string	String to insert into filename of rotated scores
center	default=T
scale	default=F
