Re: some problems with windows(rescale=) (PR#794)
Part 1) is basically that the initial rescaling is done if the window is
too large to fit on the screen. That's true and obvious (no scrollbars)
and intentional and on the help page. As ever, you need to report bugs on
what is documented, not what you would like.
This will be changed for 1.2.1, but was several hours' work. I have also
cleaned up the scrollbar behaviour.
Part 2) I just

Before reporting 4 problems with windows(rescale=) I want to congrat on R1.2 and to thank r-developers for quickly adding the rescale workaround to the windows version.
Happy New Year

some (may be related) problems with windows(rescale=) (PR#795)
If these things bother you, could you please supply fixes? For some reason
you omitted the part of the help page dealing with one of these (which is
as documented), and I also think you are confusing `plot' and `device'
sizes. The latter will be the displayed device surface, I believe.
Nothing on the help page suggested that the fine details of the R read-only
parameters will be as you

expand.grid without expanding
Dear list,
I've recently came across a problem that I think I've solved and that I wanted
to share with you for two reasons:
- Maybe others come across the same problem.
- Maybe someone has a much simpler solution that wants to share with me ;-)
The problem is as follows: expand.grid() allows you to generate a data.frame
with all combinations of a set of values, e.g.:

recode based on filter
Hi, I have a data frame DATA, which (simplified of course) looks like this:
know1 = c("Y","N","N","Y","N","N","Y","Y","N")
par1=c(1,4,5,3,3,2,3,3,5)
know2 = c("Y","Y","N","Y","N","N","N","Y","Y")

no output when run densityplot...
Hi,
I have downloaded a R script from
http://www.wessa.net/rwasp_edauni.wasp#output.
This script produces a densityplot graphic, amongst others, when is
executed from the web page.
However, when I run it in my machine the *densityplot* function produces
any output, I mean a blank graphic.
But, it's interesting if I run the following lines in the R interactive
console:

pass functions and arguments to function
Hi,
I wonder how to pass several functions and their arguments as arguments to
a function. For example, the main function is
f = function(X ) {
process1(X)
...
process2(X)
}
I have a few functions that operate on X, e.g. g1(X, par1), g2(X, par2),
g3(X, par3). par1, par2 and par3 are parameters and of different types. I
would like to pass g1, g2, g3 and their arguments to f and g1,

flexible processing
Hello,
unfortunately, I don't know a better subject. I would like to be very flexible
in how to process my data.
Assume the following dataset:
par1 <- seq(0,1,length.out = 100)
par2 <- seq(1,100)
fac1 <- factor(rep(c("group1", "group2"), each = 50))
fac2 <- factor(rep(c("group3", "group4", "group5", "group6"), each =

Error in outer() : dimension mismatch
Dear R users,
I am a new R user and have some difficulty
understanding the functioning of “outer”, where my question is from. I have
read the posts related to the questions on the outer function, but
unfortunately could not figure out where my mistake is.
I have a function with two variables and
three parameters (a density function that is not standard) and I want to draw

Two functions as parametrs of a function.
Hi R users:
I'm trying to make a function where two of the parameters are
functions, but I don't know how to put each set of parameters for
each function.
What am I missing?
I try this code:
f2<-function(n=2,nsim=100,fun1=rnorm,par1=list(),fun2=rnorm,par2=list()){
force(fun1)
force(fun2)
force(n)
p1<-unlist(par1)
p2<-unlist(par2)

Constrained Optimization, a full example
After a few days of work, I think I nearly have it.
Unfortunately, theta is unchanged after I run this (as a script from a
file). I thought that theta would contain the fitted parameters.
The goal here is to find the least squares fit according to the function
defined as "rss" subject to the constraints defined as ui and ci.
I defined ui and ci to (hopefully) force par2 and par3

Multiple options for a package
Hi R-devel,
I am facing a situation where the number of options I would like to propose
to the user is somewhat big (and could easily increase more and more as I
will code up a little more - even coming to a point where an user should be
able to implement his own options).
What we have to handle options is the couple:
options(par=value) and getOption("par")

SEM:Standard error of std.coef estimates?
Hi,
I am currently working with the sem package in R, to create pathway
diagrams. Id like to use the standardized path coeffcients. To get these, I
use std.coef. However, using this yields only the standardized coefficients,
but does not give me the standard error. Does someone know how to get
std.coef to show the standard error of the standardized path coefficients as
well?
Thanks,

Indexing in summaryBy
I'm trying to use a self-written function with the summaryBy function (doBy
package).
I have lots of data from Monte Carlo experiments comparing different
estimators across different (combinations of) parameter values, similar to
the following form:
colnames(mydata) <- c("X", "b0", "b1", # parameter combination,
corresponding (true) parameter values

Curve fit a nonlinear equation with box constraints: success, many thanks!
Dear R Helper Community!
Thank you for all your help and suggestions.
For your reference and any future person searching the archives, here is the
solution that did what I wanted it to do.
As background, my goal was to find the coefficients for the following
equation form:
y ~ c1 * x1 * x2 ^ -c2 *x3 ^ c3
where y, x1, x2, and x3 are observed data, and
c1, c2 and c3 are regression
