Pareto Plot

DESCRIPTION:

Creates a Pareto plot (vertical bar plot) from a vector.

This function is an S Version 3 generic (see Methods); method functions can be written to handle specific S Version 3 classes of data. Classes which already have methods for this function include:
lm rsm.lm fac.aov

USAGE:

pareto(x, ...) 
pareto.default(x, xnames, xmax, sigline = F,  
      prt.values = T, shade = F,  digits = 3, ...) 

REQUIRED ARGUMENTS:

x
a vector.

OPTIONAL ARGUMENTS:

xnames
vector of names to be used as labels for x. names(x) is used if it exists.
xmax
upper value of graphical parameter xlim.
sigline
If given, a structure for drawing a significance line. Used by pareto.fac.aov and pareto.lm.
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.
digits
an integer specifying the number of digits for rounding the values printed on the pareto plot. Only relevant if prt.values is TRUE.
...
graphical parameters for barplot (see par).

SIDE EFFECTS:

A vertical barplot, with bars corresponding to the values of x is produced on the current graphics device.
