getGlobalRescalingStats {CNVScope} | R Documentation |
Calculate several base statistics for color rescaling.
Description
calculates several statistics from a large matrix that can then be applied to smaller submatrices without needing to load the entire matrix into memmory
Usage
getGlobalRescalingStats(whole_matrix, saveToDisk = F, output_fn = NULL)
Arguments
whole_matrix |
the whole matrix to get stats for. |
saveToDisk |
Save the statistics to disk as an RDS file in the local directory? |
output_fn |
the name of the output file. |
Value
A list of the output statistics, including: the global min, max, length, sigma (matrix variance), pos_sigma (variance of the positive values), neg_sigma(variance of the negative values), global mean (global_mu), est_max_cap (global_mu+global_sigma_pos*2), as well as the number of rows and columns of the matrix.
Examples
load(system.file("extdata","nbl_result_matrix_sign_small.rda",package = "CNVScope"))
getGlobalRescalingStats(nbl_result_matrix_sign_small)
