c_ListofMatrixRows: Convert a matrix into list of row vectors
In natcpp: Fast C++ Primitives for the 'NeuroAnatomy Toolbox'
c_ListofMatrixRows R Documentation
Convert a matrix into list of row vectors
Description
Convert a matrix into list of row vectors
Usage
c_ListofMatrixRows(object)
Arguments
object
An integer, numeric, character or logical matrix of N rows and
M columns
Details
Typically this will be for 3D coordinates but there are no limits
on row length.
Value
a list containing N vectors of length M corresponding to the rows of
object.
Examples
## Not run:
library(nat)
xyz=xyzmatrix(Cell07PNs)
mat2list = function(m) {
um=unname(m)
lapply(1:nrow(um), function(i) um[i,])
}
bench::mark(rcpp=c_ListofMatrixRows(xyz), r=mat2list(xyz))
## End(Not run)
