rowSds: sd for each row (fast execution)

In wrMisc: Analyze Experimental High-Throughput (Omics) Data

sd for each row (fast execution)

Description

This function is speed optimized sd per row of a matrix or data.frame and treats each row as independent set of data for sd (equiv to apply(dat,1,sd)). NAs are ignored from data unless entire line NA). Speed improvements may be seen at more than 100 lines. Note: NaN instances will be transformed to NA

Usage

rowSds(dat, silent = FALSE, debug = FALSE, callFrom = NULL)

Arguments

dat	matrix (or data.frame) with numeric values (may contain NAs which will be ignored)
silent	(logical) suppress messages
debug	(logical) additional messages for debugging
callFrom	(character) allows easier tracking of messages produced

Value

numeric vector of sd values

Examples

set.seed(2016); dat1 <- matrix(c(runif(200)+rep(1:10,20)),ncol=10)
rowSds(dat1)
