methods.ggplot2
package and print/summary uses cli
package.describe()
to statistically describe variables in a data.frame according to the type.qccGroups()
now has first argument data
to extract variables from
a data frame.sd.p()
calculation now takes into sizes.attach/detach
from all examples and documentation.plot.qcc()
allows to use as.Date() objects along x-axistitle = NULL

function now returns an object of class paretoChart
with associated print and plot method.qcc-package.Rd

. qcc()
to allow a user defined control chart.qcc.option()
function so changing a parameter in .qcc.options
inside a function will make the modification persistent even outside the function environment.sizes
> 1 but no std.dev
. pareto.chart()
function.sd.xbar.one
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()
and ewma()
have been rewritten to be called directly with data and arguments. No need to create a qcc
object before.NAMESPACE
, exporting all functions with names not starting with a dot .
. std.dev
argument in qcc()
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)
.
Functions involved in such change are std.xbar()
, std.R()
, std.S()
, whereas the other sd.*
functions only have "..." argument added.chart.all = FALSE
.stats.g()
, sd.g()
, limits.g()
