Read HDF5 Files

Source: R/ReadH5.R
ReadH5.Rd

Read data from HDF5 files

Usage

# S3 method for class 'H5D'
as.array(x, ...)

# S3 method for class 'H5D'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)

# S3 method for class 'H5Group'
as.data.frame(x, row.names = NULL, optional = FALSE, ...)

# S3 method for class 'H5D'
as.list(x, ...)

# S3 method for class 'H5Group'
as.list(x, recursive = TRUE, ...)

# S3 method for class 'H5D'
as.matrix(x, transpose = FALSE, ...)

# S3 method for class 'H5Group'
as.matrix(x, ...)

Arguments

x

An HDF5 dataset (H5D) object

...

Arguments passed to other methods

row.names

NULL or a character vector giving the row names for the data frame. Missing values are not allowed.

optional

logical. If TRUE, setting row names and converting column names (to syntactic names: see make.names) is optional. Note that all of R's base package as.data.frame() methods use optional only for column names treatment, basically with the meaning of data.frame(*, check.names = !optional). See also the make.names argument of the matrix method.

recursive

Whether to recursively convert subgroups to nested lists

transpose

scTranspose the matrix before returning

Value

Varies depending on the method being called

as.array: an array with the data from the HDF5 dataset

as.data.frame: returns a data.frame with the data from the HDF5 dataset

as.list: a list with the data from the HDF5 dataset

as.matrix: a matrix with the data from the HDF5 dataset
