matlines, matpoints don't follow prototype (PR#506)
The Blue Book allows the 'type' argument to be used in matpoints and
matlines.
matlines(x, y, type="l", lty=1:5, pch=, col=1:4)
R-1.0.0 does not.
Thus, type="h", "b", must be invoked thru matplot( x, y, type = "h",
add=TRUE)
For the sake of consistency with S, it would be nice to have matlines
defined as:
"matlines" <-

Confused about specifying plot colors as RGB values
Based on reading 'rgb' documentation, I would have thought
the following would have produced identical results. Can
someone explain how to make this happen? I need to be able
to specify an array of rgb values for the 'col' parameter.
colnames.col <- c("black", "red", "blue", "green")
colnames.rgb <- apply(as.matrix(colnames.col), 1,

persp() problem
I am having some trouble getting the persp() package to change the x
and y axis on a 3d plot. It defaults to the [0,1] interval and when I
try to change it I get errors.
Example:
This works:
------------
D <- c(1,2,3,4,5,6,7,8,9,10)
M <- c(11,12,13,14,15,16,17,18,19,20)
DM <- cbind(D,M)
persp(DM, theta = 40, phi = 30, expand = 0.5, col = "lightblue",
ltheta = 120,

persp, array and colors
Dear R-users,
I'd like to plot a three-dimensional surface and at the meantime I'm using
an array. I would like to have the values of my first matrix in the heights
of the plot and the colors of the single facet taking into account the
second matrix.
I hope that the next code will help all of you to understand better my
issue,
Thanks in advance, Giancarlo

persp(); help with 'tck' option
Hi All,
I'm using 'tck' option to *reduce* the length of tick marks but it is not
working, can anyone please tell me where I'm going wrong...
require(graphics)
require(grDevices)
x <- seq(-10, 10, length= 30)
y <- x
f <- function(x,y) { r <- sqrt(x^2+y^2); 10 * sin(r)/r }
z <- outer(x, y, f)
z[is.na(z)] <- 1

bug in xfig()?
I'm using (Linux version) xfig() within a function
and then simple matplot() and matline() plots.
Although I do not define any bg or fg default color,
sometimes all lines in the final fig file are green.
The same code works as (I) expected if I use
x11() or pdf().
This is what I'm doing:
I open 2 devs:
xfig()
dev.set(2)
layout(mat1)
xfig()

Adding Text to a persp plot using specific coordinates
Hi folks,
I'm experiencing some hassle to add some text on a persp plot...
Here is the code to generate the persp plot:

y <- seq(-1.95, 1.95, length = 30)
z <- outer(x, y, function(a,b) a*b^2)
persp(x, y, z,xlim=c(-2,2),ylim=c(-2,2),zlim=c(-8,8), phi=30, theta=-30,nticks=8,ticktype="detailed")

Combining Custom and Preset Linetypes
Dear R-Users,
I created the xyplot below using 10 groups (9 groups + 'Total' of all
groups) with lty=1:10. I need the 'Total' to be a bold solid line (lty=1)
where as the 9 groups just need to be distinguishable from each other. As
you can probably see, when the group reaches CRA6 the lty starts from 1
again. I have tried to specify ten unique lines using lty=

persp(): add second plane (second, long question)
Thank you for your replies so far.
Sorry for bothering you again, but I'm still not able to get what I need as
I don't understand all parts of the replies (just using R for easy
things....).
Is there a code for plane3d() like some of you sent me for points3d()? I was
not able to get that out of the scatterplot3d package...
What I can do is to get the x,y and z-range for the xlim,ylim and

persp plot + plotting grid lines
Dear all;
Does anyone know how to add grid lines to a persp plot? I've tried
using lines(trans3d..) but the lines of course are superimposed into
the actual 3d surface and what I need is something like the plot shown
in the following link:

I'll appreciate any ideas

WMF conversion...
Hello R-Help,
I've got a bit of an issue with WMF's. I am working on WindowsXP and outputting WMF format images. I then take the WMF format images and insert them in PowerPoint. I take the PowerPoint and convert it to PDF.
The WMFs are nothing special. Just the typical x-y plot with a gray dotted grid added and a few matlines. The WMFs, when produced look great! They show

help with predict and plotting confidence intervals
Dear R help,
This seems to be a commonly asked question and I am able to run examples that have been proposed, but I can't seems to get this to work with my own data. Reproducible code is below. Thank you in advance for any help you can provide.
The main problem is that I can not get the confidence lines to plot correctly.
The secondary problem is that predict is not able to find my object

persp(): add second plane
Dear R-users,
is it possible to add a second plane to the persp()-plot? I couldn't find
any hint on that in the news archive...
I'm using R.1.4.1 for Windows.

I had to use a glm instead of my basic lm on some data due to unconstant

now, when I plot the model over the data, how can I easily get the 95%

persp plot
I have a set of data in the form
x1, y1, z1
x1, y2, z2
...
x1, yN, zN
x2, y1, z(N+1)
x2, y2, z(N+2)
...
x2, yN, z(2N)
...and so on...
xM, yN, val(M*N)
I have been trying to figure out how to get R to use this data in a
persp plot. So far the only thing that I can figure out to do is to
break the data file into three different files. The first file
contains the x-coordinate data:
