Plotting w/multiple y-axes?
How do I plot using multiple(2) y-axes?
I have two series that use the same x-data, but have very different scales.
Appreciate any feedback,

Different y-axes
Hi All,
I have checked everything I could find abot graphics, but still cannot
solve the problem.
Are there any ways to make a graph that plots two lines and two
different y-axes, each of them has a scale that is related to the
respective line. For example, y1 has a range 1:50 and y1 ranges 0:1. The
x-axe is the same for both.
Thank you in advance.

Second axis in a plot
Hi to all,
First of all, I prefer to tell that I am a R-newbie,
so I apologize if this is a silly question (I have
tried looking in the manuals, but without luck).
I have two variables, y and z, that I want to plot
against x in the same plot. I have done this before,
using points() after plot(). But now the problem is
that y and z are in different units of measurement,
and their ranges are very

Thank you very much peter.
It worked out nicely.
I have additional question. How can I get Y-axis on log-scale?

approxfun-problems (yleft and yright ignored)
Dear all,
I have run into a problem when running some code implemented in the
Bioconductor panp-package (applied to my own expression data), whereby gene
expression values of known true negative probesets (x) are interpolated onto
present/absent p-values (y) between 0 and 1 using the *approxfun -
function*{stats}; when I have used R version 2.8, everything had
worked fine,

r: plots
hi all
i have another probably simple question.
I have three variables say x, y and z. x and y are quite large and z is
relative small.
how can one plot the three variables on the same graph with two separate
axis?
(one for x and y and the other for z)
e.g.
x<-c(101,110,150,167,120)
y<-c(120,135,175,95,200)
z<-c(0.001, 0.15, 0.6, 0.8, 1)

adding percentage secondary y-axis
Hi
It is usually not recommended but if you insist
maybe
library(plotrix)
?twoord.plot
twoord.plot(lx=D[,1],ly=D[,2], rx=D[,1], ry=D[,3])
or
plot.yy(x=D[,1],yright=D[,3], yleft=D[,2])
which allows only one x axis (see below).
Cheers
Petr
plot.yy <- function (x, yright, yleft, yleftlim = NULL, yrightlim = NULL,

ecdf with lots of ties is inefficient (PR#7292)
Full_Name: Martin Frith
Version: R-2.0.0
OS: linux-gnu
Submission from: (NULL) (134.160.83.73)
I have large vectors containing 100,000 to 20,000,000 numbers. However, they
only contain a few hundred *distinct* numbers (e.g. positive integers < 200).
When I do ecdf(v), it either runs out of memory, or it succeeds, but when I plot
the ecdf with postscript, the output is unnecessarily bloated

shade overlapping portions of circles (or other shapes)
I'm making some illustrations and it would be convenient to
automatically shade the overlapping portions of circles. These
illustrations are for Social Choice theory, a field in political
science and economics. I've wrestled together some examples so you
can see what I mean, but have not mastered the "color overlapping
sections" problem (as you will see):

How to use result of approxfun in a package?
I am working on a project where we start with start with 2 long,
equal-length vectors, massage them in various ways, and end up with a
function mapping one interval to another. I'll call that function
"f1." The last step in R is to generate f1 as the value of the
approxfun function. I would like to put f1 into a package, but
without having the package redo the creation of

help with the coordinates of the ECDF object
Hi all R users
I would like to know how acess the coordinates
of the ECDF object.
I look for the example,
in this part:

but I do not know to extract
the Y coordinate and put it in other variable.
My objective is to make a plot
and identify the points with labels.

Hi people,
I am new in this list and could not find a FAQ for it in particular,
furthermore I could not find my question answered in the official R
FAQ or docs.
I have simply something like this:

and f is:

build a SpatialLines object from a list
Hi Ashraf,
It is not obvious to me what your structures are but one problem in your
function is the assignment tt1 <- SpatialLines(list(tt[[i]])).
This will set tt1 to just have one item.
Consider the following
test.func <- function(x) {
tt1 <- list()
for ( i in ... ) {
...
tt1[[i]] <- SpatialLines(tt[[i]])
}
return(tt1)
}

build a SpatialLines object from a list
Hi Eric,
Thanks for the help.But this will not solve the problem as it will generate a list and what I need is an object of class sp using SpatialLine function from sp package.So, I need to convert each matrix to coordinates and then to a line and then to a spatial line as figured in the code.
My data structure is a list of 141 matrices.Each matrix represents coordinates of the river lines

help on stepfunction
Dear members,
I would like a help for extracting the values from a step function
(stepfun).
>From help(stepfun) we have the following example:
Y0<-c(1.,2.,4.,3.)
y0<-c(1.,2.,3.,4.)
sfun<-stepfun(1:3,y0,f=0)

Now, suppose instead I was given the object (*sfun*, say) from which I
wanted to extract the values generated by the function *stepfun*. More
precisely, I want to
