Calculate standard deviation of x, where x can be
an rvec. If x is an rvec, separate standard deviations
are calculated for each draw.
Usage
sd(x, na.rm = FALSE)
Value
An rvec, if x is an rvec. Otherwise
typically a numeric vector.
Arguments
x
A numeric vector or R object, including an rvec().
na.rm
Whether to remove NAs before calculating standard deviations.
Details
To enable different behavior for rvecs and for ordinary vectors,
the base R function stats::sd() is turned into a generic,
with stats::sd() as the default.
For details on the calculations, see the documentation
for stats::sd().
