Write Matrix to HDF5 file

Description

Function writes matrix object to an HDF5 file.

Usage

matrix2h5(matrix, h5file, name = "assay", overwrite = TRUE)

Arguments

matrix	matrix to be written to HDF5 file, row and column name slots need to be populated
h5file	character(1), path to the hdf5 destination file
name	The name of the dataset in the HDF5 file. The default is write the score matrix (e.g. z-score, logFC) to the 'assay' dataset, users could also write the adjusted p-value or FDR matrix to the 'padj' dataset by setting the name as 'padj'.
overwrite	TRUE or FALSE, whether to overwrite or append matrix to an existing 'h5file'

Value

HDF5 file containing exported matrix

Examples

mat <- matrix(rnorm(12), nrow=3, dimnames=list(
              paste0("r",1:3), paste0("c",1:4)))
h5file <- tempfile(fileext=".h5")
matrix2h5(matrix=mat, h5file=h5file, overwrite=TRUE)
