Hi all:
Is there a plot tool to use different color indicates difference magnitude of data?
The plot is in the attachment.

Many thanks.

No sure what you want exactly as there is no attachment here.
Here are an example of what can be done:

x <- 1:128
y <- rnorm(128, 10, 2)

z <- x+y

nbcol <- heat.colors(128)

# standardize z to be from 1 to 128
zcol <-  ((z-min(z))/(max(z)-min(z)))*127+1

# different examples
plot(x, y, col=nbcol[zcol], pch=".", cex=10, bty="n")
plot(x, y, col=nbcol[zcol], pch=".", cex=zcol/10, bty="n")
plot(x, y, col=nbcol[128-zcol], pch=".", cex=10, bty="n")

Sincerly

Not strange at all. This list does not accept binary attachments, as
detailed in the posting guide linked at the bottom of this and every

The R-help list strips most attachements other than text (and perhaps pngs? ) to deduce the risk of virus or malware being recieved.  

You could try parking the file on something like medifire and providing a link here.

If you are just looking for a range of colors that communicate low to high
values, try package RColorBrewer and look at the sequential palettes.

More accurately the server strips all files of type that are not in the set:  MIME-TEXT, pdf, png.

Most mail clients will not label files ending in .dat, .csv or .fil as mime-text and so many files which would otherwise be helpful  and are ASCII files do get discarded. I do not think that the server applies a test to the extension but rather that the mail clients are causing the problem by labeling them something else.

I am attaching an ascii file with an extension `.dat`. I expect it to be stripped.

Thanks David. The clarification helps.  I had forgotten that pdfs would get through.

Howeve the file got to me, I suspect because I am listed in the To line under my actual email address.  I suspect that only meng and I recieved it and the rest of the list did not.

My mail client labeled that attachment as:
------

--Apple-Mail-83-489973374
Content-Disposition: attachment;
	filename=junk.dat
Content-Type: application/octet-stream;
	name="junk.dat"
Content-Transfer-Encoding: 7bit
---------

... and the server stripped it, since it was expecting something like this:

--Apple-Mail-83-489973374
Content-Transfer-Encoding: quoted-printable
Content-Type: text/plain;
	charset=us-ascii

And I am here attaching a file I expect to remain attached:

Hi meng,
I think that the color.scale function (plotrix), which linearly 
transforms numeric values to colors, might be what you want.
