rowSds R Documentation
sd for each row (fast execution)
Description
This function is speed optimized sd per line (takes matrix or data.frame and treats each line as set of data for sd, )equiv to using apply.
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)
Arguments
dat
matrix (or data.frame) with numeric values (may contain NAs)
Value
numeric vector of sd values
See Also
sd
Examples
set.seed(2016); dat1 <- matrix(c(runif(200)+rep(1:10,20)),ncol=10)
rowSds(dat1)
