[ychu066]

http://old.nabble.com/file/p26418382/hist1.png hist1.png  i want three plots
along on the side , how to i do that ?

 and I also want to change the colour of the bars for each plot, how do i do
that ?

i got the code here to draw that ..
columns <- 8:153 
plots <- vector("list", length(columns)) 
j <- 0 
for (i in columns) 
{   
  plots[[ j <- j+1 ]] <- 
    histogram( ~ data[,i], 
      ylab = "Frequency", xlab = "Score", 
      xlim = c(1,5), ylim = c(0,100), 
      main = colnames(data)[i]
    ) 
} 

print(plots[[1]]) 

# or export 

for (i in seq_along(plots)) 
{ 
  png(paste("hist", i, ".png", sep = "")) 
  print(plots[[i]]) 
  dev.off() 
}
