bdAdd_hdf5_matrix: Write matrix to existing hdf5 file

In BigDataStatMeth: Statistical Methods and Algorithms for Big Data

Write matrix to existing hdf5 file

Description

Creates a hdf5 file with numerical data matrix,

Usage

bdAdd_hdf5_matrix(
  object,
  filename,
  group,
  dataset,
  transp = NULL,
  force = FALSE
)

Arguments

object	numerical data matrix
filename,	character array indicating the name of the file to create
group,	character array indicating folder or group name to put the matrix in hdf5 file
dataset,	character array indicating the dataset name that contains the matix data
transp,	boolean if true, data is manipulated in transposed form
force,	optional boolean if true and file exists, removes old file and creates a new file with de dataset data.

Value

none

Examples

matA <- matrix(c(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15), nrow = 3, byrow = TRUE)
matB <- matrix(c(15,14,13,12,11,10,9,8,7,6,5,4,3,2,1,5,3,4,5,2,6,2,3,4,
                   42, 23, 23, 423,1,2), nrow = 3, byrow = TRUE)
                   
bdCreate_hdf5_matrix_file("BasicMatVect.hdf5", matA, "INPUT", "matA")
bdAdd_hdf5_matrix(matB, "BasicMatVect.hdf5", "INPUT", "matB")

# Remove file (used as example)
  if (file.exists("BasicMatVect.hdf5")) {
    # Delete file if it exist
    file.remove("BasicMatVect.hdf5")
  }
