In mccoy-lab/rhapsodi: R haploid sperm/oocyte data imputation

This function changes random indices to NA, in effect removing data

Description

This function takes as input a matrix and carries over its data to a vector Then num_nas number of locations are randomly chosen in that vector and overwritten by NA Finally, the vector is reshaped to a matrix matching the size and dimension of the input and returned This function is efficient for lower numbers of NAs (i.e. higher coverage samples)

Usage

sim_add_na_flatten(to_change, num_nas, num_gametes, num_snps)

Arguments

to_change	a matrix, the original data, with nrow of num_snps and ncol of num_gametes
num_nas	an integer, the number of positions that should be randomly chosen to switch to NA
num_gametes	an integer; the number of gametes or the number of columns for to_return
num_snps	an integer; the number of SNPs or the number of rows for to_return

Value

to_return a matrix with nrow of num_snps and ncol of num_gametes. The data is a combination of locations carried over from the input to_change and locations that were switched to NAs
