Description

Merge matrix rows/columns according to a partition of row indices

Usage

merge_by_partition(
  m,
  partition,
  agg = Matrix::colSums,
  n_cpu = 1,
  check = FALSE
)

Arguments

m	A matrix
partition	A list of integer vectors, which makes a full partition of the rows of m
agg	Function. The function that will be called to merge the rows. Must return a matrix with the same number of columns and as many rows as needed. Default is colSums.
n_cpu	Integer. Number of cores to be used for the calculation, passed to the parameter mc.cores of the function mclapply. Default is 1 which means the "regular" lapply will be used.
