dat	A matrix or data frame to be plotted.
group	A factor or vector giving group information of columns of dat.
col	A strings of colors recognized by the plot function. Or a vector of color values. For more details, see ?colors.

data(iris)
grpplot(iris[,1:2], iris[,5],main="IRIS DATA",legend.loc="topleft")

## color values for the group and symbol size

## color and symbols for the group. legend location
grpplot(iris[,c(1,3)], iris[,5], col=c("red", "green3", "blue"),
        pch=c(15,16,17), main="IRIS DATA",legend.loc="topleft")
      
## plot vector
grpplot(iris[,3], iris[,5],main="IRIS DATA",legend.loc="top")

## pairs plot. 
grpplot(iris, iris[,5],main="IRIS DATA")
