Split hdf5 dataset

Description

Split hdf5 dataset by rows or columns and store splitted submatrices inside hdf5 file.

Usage

bdSplit_matrix_hdf5(
  filename,
  group,
  dataset,
  outgroup = NULL,
  outdataset = NULL,
  nblocks = NULL,
  blocksize = NULL,
  bycols = TRUE,
  force = FALSE
)

Arguments

filename,	character array indicating the name of the file to create
group,	character array indicating the input group where the data set to be imputed is.
dataset,	character array indicating the input dataset to be imputed
outgroup,	optional character array indicating group where the data set will be saved after imputation if 'outgroup' is NULL, output dataset is stored in the same input group.
outdataset,	optional character array indicating dataset to store the resulting data after imputation if 'outdataset' is NULL, input dataset will be overwritten.
nblocks,	integer number of blocks in which we want to split the data
blocksize,	integer, number of elements in each block
bycols,	boolean by default = true, true indicates that the imputation will be done by columns, otherwise, the imputation will be done by rows
force,	boolean if true, previous results in same location inside hdf5 will be overwritten.

Value

Original hdf5 data file with imputed data
