now allows to estimate the standard
deviation by using the moving range (default as in the previous
versions) or the method suggested by Ryan (2000) using the scaled std
deviation of the observations.cusum()

have been rewritten to
be called directly with data and arguments. No need to create a

function. It now allows to give a numerical value or a sting identifying
a method for estimating the standard deviation of a continuous process
variable. Thus, these methods are only available to “xbar”, “R”, and “S”
charts. For details see help(qcc)
