Create a Pareto Plot of Effects
DESCRIPTION:
Creates a Pareto plot (vertical bar plot) of t-values
obtained from a response surface fit.
USAGE:
pareto(x, sig=.05, prt.values = T, shade =
F,...)
REQUIRED ARGUMENTS:
- x
-
output from fitting a response surface using
rsm.lm
.
OPTIONAL ARGUMENTS:
- sig
-
significance level for t-distribution significance.
lines.
- prt.values
-
a logical flag for whether values are printed at end of bars.
- shade
-
logical flag for whether will be shaded or filled with solid colors.
- ...
-
graphical pars passed to barplot (see
par
).
SIDE EFFECTS:
A Pareto plot of t-statistics from response surface fit is plotted on the current graphics device.
