rcpp_hdf5dataset_colSds: Column standard deviations of an HDF5 dataset (R6 wrapper)
In BigDataStatMeth: Title: Scalable Statistical Computing with HDF5-Backed Matrices
rcpp_hdf5dataset_colSds R Documentation
Column standard deviations of an HDF5 dataset (R6 wrapper)
Description
Block-wise, OpenMP-parallel computation of apply(X, 2, sd).
Uses Bessel's correction (n-1).
Usage
rcpp_hdf5dataset_colSds(ptr, paral = NULL, wsize = NULL, threads = NULL)
Arguments
ptr
External pointer (SEXP) to an open hdf5Dataset.
paral
Logical or NULL; enable OpenMP parallelisation.
wsize
Integer or NULL; block size (NULL = auto).
threads
Integer or NULL; thread count (NULL = auto).
Value
Numeric vector of length ncols_R.
