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.

EXAMPLES:

ab.rsm <- rsm.lm( abrsm.df) 
pareto(ab.rsm)
