CommonFG-DataSet: Functions to Create/Open DataSets in `CommonFG` objects

Description

Although DataSet objects can implicitly be created using subsetting operators (see CommonFG) h5 implements more explicit functions (used by subsetting operators under the hood) to create and open DataSets.

Usage

createDataSet(.Object, datasetname, data, type, dimensions,
  chunksize = ChunkSize(data), maxdimensions = rep(NA_integer_,
  length(GetDimensions(data))), compression = 4L, size = -1)

  ## S3 method for class 'CommonFG,character,missing,character,integer,ANY,ANY,ANY,ANY':
createDataSet(.Object,
  datasetname, type, dimensions, chunksize, maxdimensions, compression, size)

  ## S3 method for class 'CommonFG,character,ANY,missing,missing,ANY,ANY,ANY,missing':
createDataSet(.Object,
  datasetname, data, chunksize, maxdimensions, compression)
openDataSet(.Object, datasetname, type)
## S3 method for class 'CommonFG,character':
openDataSet(.Object, datasetname, type)

Arguments

.Object

CommonFG; S4 object of class CommonFG;

datasetname

character; HDF5 DataSet name to be used.

data

object; Object to be stored in HDF5 file, can be either of type vector, matrix or array.

type

character; Character specifying data type, can be either one of: [object Object],[object Object],[object Object],[object Object]

dimensions

integer; Dimensions of dataset to be created.

chunksize

integer; Chunksize to be used for dataset.

maxdimensions

integer; Maximum dimensions used for dataset, NA is mapped to 'unlimited'.

compression

integer; Default GZIP compression level to be used, from 0 (no compression) to 9 (maximum compression), defaults to 4.

size

integer; Size of data type to be used, only relevant for character strings.
