asp=1 and aspect ratio
Hi everyone
I want a square scatterplot with abline(0,1) going exactly through the
SW and NE corners. By "square" I mean that the plotting region is
exactly square, and that the axis limits are identical.
x <- 1:20
y <- x+rep(c(-1,1),10)
lims <- range(c(x,y))
None of the following do this:
plot(x,y) ; abline(0,1) #not square
plot(x,y,asp=1);abline(0,1) #diagonal

need help with axis ticks
hi,
i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the
problem that i am having is that the axis tick labels are far away from the
ticks and going into previous plots (see attached figure). i need to know
how can i reduce the distance between the ticks and their values (y axis
values).the part of the code that i am using (after reading in the data) to
create the top row is:

adding a curve with xaxs="i"
I want the curve to touch the y axis like the curve touches the upper boundary.
How can I eliminate the margin between axis and curve on the left side?
x1 <- c(1,2,3,4,5)
x2 <- c(2,4,6,8,10)
mod <- lm (x2~x1)
hm <- function (x) (mod$coe[1]+x*mod$coe[2])
plot.new()

boxplot and bxp do not respect xlim by default (PR#9754)
Full_Name: Steve Ellison
Version: 2.4.1
OS: Windows, Linux
Submission from: (NULL) (194.73.101.157)
bxp() allows specifcation of box locations with at=, but neither adjusts xlim=
to fit at nor does it respect xlim provided explicitly.
This is because bxp() now includes explicit xlim as c(0.5, n+0.5), without
checking for explicitly supplied xlim (or ylim if horizontal).
This also prevents

image() with a vector
Hi,
I have a vectors x and z, for example,
x <- 0:20
z <- round(runif(20,1,7))
y <- 0.5
and I want to display z as an image. However if I then call image() with a vector
image(x,y,t(z),zlim=c(1,7),col=heat.colors(7),xlab="Year",ylab="Action",yaxt="n",xaxs="r",yaxs="r")
then I get the error

axis and times() problem
Dear R-Group,
the first example is working as expected, but I need the plot without
the box,
normally no problem, but I am not able to get the x-axis formatted as
times with the axis, command.
I tried a lot of things, nothing was working so I used the most easy
axis command in the second example here ....

parameter yaxs / function hist (graphics)
Dear R users,
The parameters xaxs and yaxs (function par, package graphics)
seem not to work with the function hist (package graphics),
even when the parameters xlim and ylim are defined.
Is there any way to make yaxs="i" and xaxs="i" work properly
with the function hist, mainly to produce histograms that
"touch" the horizontal axis? The R documentation and the

color graph in multiple plots
Hi,
I would like to distinguish my plots using colors but I got error message. How do I correct that?

Newbie error or bug?
Hi
I used R for the first time yesterday. I wanted to plot the aliasing
effect of sampling a 5.5KHz sinusoid at only 8KHz (below the Nyquist
limit). So I wrote a small R script that a) plots 1msec worth of a
5.5KHz sin wave b) plots 1msec of the resulting 2.5KHz alias and c)
plots the 8 sampling points on the 5.5KHz source wave. I think I have
found a bug. The script is as follows:

setting x-y axis at origin
Hello -
I'm just getting into 'R' and am having trouble setting up the x-y axis
to share (0,0). In the example posted here:
http://geocities.com/chris_ciotti/Images/part1.pdf, each axis has a 0
which I do not want.
Any help on getting a graph starting at (0,0) would be greatly
appreciated.

is it possible to draw a box around the following barplot;
using "box=TRUE" won't work.

Alignment of axes intersection
All,
Very basic question I can't seem to find the answer to:
plot(0:10, 0:10)
The axes intersection is not aligned at (0,0) in the lower left.
How does one force this?
I searched for graphical parameters under par(graphics) but can't seem to
find it.
Thanks!

I would like my axes to intersect at (0,0). I tried xaxs="i",yaxs="i" but it

Another plot question
Here is another, perhaps trivial, plotting question.
I am making a filled contour plot and have almost everything dialed in
the way I want it. The last hurdle (that I can foresee) is adjusting the
look of the key. I'm plotting the 25%, 50%, 75%, and 95% quantiles and I
want the key to be evenly spaced, e.g., the width of the 25% and the 95%
should look the same on the key. They are labeled

overlap cdf plots and add colors and etc
Hi r-users,
I would like to overlap 2 ecdf plots.
I tried this below and it gives me two plots of ecdf but just both just in
black.
par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),xaxs="i", yaxs="i")
plot(ecdf(datobs))
lines(ecdf(gam_sum_gen))
Then I try to add colors etc and also the legend but fail.

How to color a region in a contour plot with the contour being the boundary?
Dear expeRts,
I would like to color a certain region in a levelplot. The region for z <= 0.02 should have a dark gray color. Below is a minimal example. It almost does what I want, but The region between z=0.02 and z=1 is also colored in dark gray (instead of just the region for z <= 0.02).
How can I solve this?
Cheers,
Marius

overplots - fixing scientific vs normal notation in output
Moving from S-plus to R I encountered many great features and a much
more stable system.
Currently, I am left with 2 problems that are handled differently:
1) I did lots of "overplots" in S-Plus using
par(new=T,xaxs='d',yaxs='d') to fix the axes
->What is the workaround in R ?
2) In S-Plus I could fix "scientific notation" or "normal notation" in
