| matrix_info {geneExpression} | R Documentation |
matrix_info(file);the summary information of a csv/tsv/xls table file is not implemented at this moment, an NotImplementedException will be thrown for such kind of the input file.
A tuple list object that contains the data information which is extract from the given file:
sampleID: a character vector that contains the matrix sample information(column features name)
geneID: a character vector that contains the matrix gene features information(row features name)
tag: the matrix source tag label, could be the file basename if the given input file is a file path to the matrix.
if the input file object is a Matrix expression matrix object, then an additional mad data slot will be added into the result list: the MAD value of each gene feature row. the list data also has some specificied data fields: list(sampleID, geneID, tag, mad).
str(matrix_info(file = "/path/to/expr_mat.csv"));
