Arguments

x	A matrix or data frame to be plotted.
y	A factor or vector giving group information of columns of x.
plot	One of plot types: strip, box, density and pairs.

Examples

  data(iris)
  grpplot(iris[,1:4], iris[,5],plot="strip", main="IRIS DATA")
  grpplot(iris[,1:4], iris[,5],plot="box", main="IRIS DATA")
  grpplot(iris[,1:4], iris[,5],plot="density", main="IRIS DATA")
  grpplot(iris[,1:4], iris[,5],plot="pairs",main="IRIS DATA",ep=2)

  ## returns an object of  class "trellis".
  tmp <- grpplot(iris[,c(2,1)], iris[,5],main="IRIS DATA",ep=2)
  tmp
  
  ## change symbol's color, type and size
  grpplot(iris[,c(2,1)], iris[,5],main="IRIS DATA", cex=1.5,
