R Scatter plot partially generated in Fedora

Hi:

I?have installed R?first time in Linux/Fedora. I used the yum command
(yum install R). The installation was successful and went without any
errors. I could also run the following R script without any errors.
But, the generated scatter plot only has three blue dots added through
the first plot(...) statement. It does not show the main title,
x-/y-axes, x-/y-labels, and also the green dots added through
points(...) statement.

I don't know if this is an installation problem. Please help.

Linux version:
===========

Linux domU-12-31-39-03-00-76 2.6.21.7-2.fc8xen #1 SMP Fri Feb 15
12:39:36 EST 2008 i686 athlon i386 GNU/Linux

R version:
========

Installed Packages
Name?????? : R
Arch?????? : i386
Version??? : 2.8.0
Release??? : 2.fc8

R Script:
=======

png(filename="a.png", height=295, width=300,? bg="yellow");
x <- c(12, 14, 16);
y <- c(7, 12, 10);
plot(x, y, col="blue", main="Test", xlab="X", ylab="y");
x2 <- c(10, 15);
y2 <- c(8, 12);
points(x2, y2, col="green");
dev.off();

Thanks

Your R install is fine. You plot commands are wrong, though.

Also no need for semicolons at end of lines anymore.

Note your first x axis goes from 12, 16.

then later you try to write points at 10, which are out of bounds.  if
you want to write at 10, re-do your figure.  This code shows 5 points
on graph.

plot(x=c(7,18), y=c(6,14) , type="n", main="Test", xlab="X", ylab="y")

x <- c(12, 14, 16);
y <- c(7, 12, 10);
points(x,y, col="blue")
x2 <- c(10, 15);
y2 <- c(8, 12);
points(x2, y2, col="green");

After it looks good on screen, then wrap in the png commands.
