Hi R Users!
 
Thanks in advance.
 
I am using R-2.5.1 on Windows XP.
 
I am trying to do a stacked bar plot, but could not get through the following problem. The code is given below.
   
  1. How can I provide 15 different colors for each method with 15 Rows?
   
  2. How can I put the legend in a particular position (eg., in the top or bottom or right or left)? How can I put legend using a number of rows (eg., using two or three rows)? 
  
Once again thank you very much for your time.
 
Regards,

  The Code:
   
  library(lattice)
library(graphics)
   
  x <- matrix(1:75, ncol= 5)
dimnames(x)[[2]] <- paste("Method", 1:5, sep="")
dimnames(x)[[1]] <- paste("Row", 1:15, sep="")
   
  # library: graphics
   
  barplot(x,
        beside=FALSE,
        col= 1:nrow(x),        
        legend= rownames(x)        
       )
   
  # library: lattice
   
  barchart(Freq ~ Var2,
         data = as.data.frame.table(x),
         groups = Var1, stack = TRUE,
         auto.key = TRUE)
