Simulate a Signature Matrix — simulate_signature

This function simulates a matrix where each column corresponds to a signature, and each entry in the matrix is a random proportion of a set of channels. The proportions in each column sum to 1.

Usage

simulate_signature_matrix(signatures, channels, digits = 2, seed = NULL)

Arguments

signatures: A vector of signature names to be used as column names in the resulting matrix.
channels: A vector of channel names to be used as row names in the resulting matrix.
digits: Integer value indicating the number of decimal places to which the proportions should be rounded. Default is 2.
seed: An optional seed value for reproducibility. Default is NULL, meaning no seed is set.

Value

A matrix where rows represent channels and columns represent signatures. Each entry is a randomly generated proportion, and the values in each column sum to 1.

Examples

signatures <- c("Signature1", "Signature2", "Signature3")
channels <- c("Channel1", "Channel2", "Channel3")
simulate_signature_matrix(signatures, channels, digits = 2, seed = 123)
#>          Signature1 Signature2 Signature3
#> Channel1       0.19       0.47       0.27
#> Channel2       0.53       0.50       0.45
#> Channel3       0.28       0.02       0.28
