Problem with "outer" function
Hello,
I am having a problem with the "outer" function.
I am using R 1.9.1 on Windows 2000. My problem may be described as follows:
I have a function f of 3 variables and 3 vectors, aa, bb and cc. I would like
to evaluate this function in a 3-dimensional grid of points corresponding to
all combinations of the elements of the 3 vectors. For example, if
aa<-c(1,2)
bb<-c(3,4)

R 1.5.0 on Jaguar?
It seems that someone was having trouble compiling R under Mac OS X 10.2,
but I'm wondering if anyone is running the version available from
http://www.apple.com/downloads/macosx/math_science/rformacintosh.html under
OS X 10.2. This is important because I'm about to take delivery of a new
Power Mac running 10.2!

problem with putting text in outer margins (mtext outer=TRUE)
Hi there,
I'm trying to get some text in the outer margins of my plots and am
having trouble - the margin text is overlapping my plots, even though
the outer margin I'm trying to put it in is very big.
I've simplified my problem down to this:
-------------------------
X11(width=7.5,height=10)
par(mfrow=c(6,1),oma=c(20,0,20,0), mar=c(0,3.1,1,2.1))

groupedData Error Using outer=TRUE
I'm using groupedData from nlme. I set up a groupedData data.frame with
outer=~group1. When I try to plot with outer=TRUE, I get "subscript out
of bounds." This happens most of the time. When it works, I get
spaghetti-type plots for comparing groups. But I don't understand why it
doesn't usually work.

outer not applying a constant function
Hi,
the function outer can not apply a constant function as in the last line of the following example:
> xg <- 1:4
> yg <- 1:4
> fxyg <- outer(xg, yg, function(x,y) x*y)
> fconstg <- outer(xg, yg, function(x,y) 1.0)
Error in outer(xg, yg, function(x, y) 1) :
dims [product 16] do not match the length of object [1]
Of course there are simpler ways to construct a constant

A problem with using the "outer" function
Hi:
I am using R 1.7.0 on Windows. I am having trouble getting "outer" to
work on one of my functions. Here is a simple example illustrating my
problem:
> b1 <- c(1.2,2.3)
> b2 <- c(0.5,0.6)
> x <- c(3e+01, 1e+02, 3e+02, 5e+02, 1e+03, 1e+04, 1e+05, 1e+06)
> y <- c(2,4,2,5,2,3,1,1)
> n <- c(5,8,3,6,2,3,1,1)

outer
Dear r-plus users,
i would like to use outer in the following case outer(x,y,FUN="fun")
i suppose that my function fun is of the following form:
fun<-function(x,y)
{
if(y>x) return(x+y)
if(y<=x) return(0)
}
My problem is that the command outer(x,y,FUN="fun") return me a
null matrix instead of an upper triangular matrix.
Is somebody have a solution ?
Thanks for your

A problem about outer()
Dear all,
I have something about function outer() that I can't understand. Just see the following example. The two NaNs are due to 0/0, but I can't figure out the cause of the last two errors. I wonder if some one can explain this for me.

outer not applying a constant function
> Or is this a bad idea?
I don't like the proposal. I have seen code like the following (in
fact, I have written such code, where I had forgotten a function was
not vectorized) where the error would have been discovered much later
if outer() didn't catch it.
> outer(1:3, 11:13, sum)

outer(-x, x, pmin) cannot allocate
R> x <- 0. + 1:8000
R> y <- outer(-x, x, pmin)
Error: cannot allocate vector of size 1000000 Kb
Why does R need to allocate a gigabyte to create an 8000 x 8000 matrix?
It doesn't have any trouble with outer(-x, x, "+"). Thanks.

Wishlist: mention Vectorize in 'outer' man page (PR#10490)
Full_Name: Antonio, Fabio Di Narzo
Version: 2.6.1
OS: linux
Submission from: (NULL) (213.140.16.187)
In 'outer' man page, there is no mention of the Vectorize function.
Moreover, I think it isn't underlined enough that the FUN argument to 'outer'
must be a vectorized function (doc speaks about a function which has to 'operate
elementwise').

outer() function
Greetings R-help community,
I am relatively new to R, which may be why I am having trouble
understanding this problem. I am trying to use outer() to generate a
graphable surface of a function. If there is a better way to do this,
I would appreciate the insight. Otherwise, could someone suggest a
method to get the outer() function to work here?
Below is my simplified R program. Further down

main title in plot; outer=TRUE (cut off)
Hello,
I'm trying to position a plot title "1 a)" in the top left corner of a
graph; i've set outer=TRUE for it to be in the outer margin unfortunately
this is cut off. Is there a way either to make it so that it is not cut off
or increase the number of margins and then place it in margin below the
outer?
Heres what I have so far

outer
I've just begun playing around with defining functions in R and
I'm not really sure what's going on in the following situation.
I've defined the following function:
gcd <- function(x,y) {
x <- as.integer(x); y <- as.integer(y)
q <- as.integer(x / y)
r <- x - q * y
if (r==0) y else gcd(y,r)
}
As expected, it gives the following results:
> gcd(3,2)

'at' parameter in mtext(.., adj=0, outer=T) (PR#396)
Depending on the setting of par()$usr,
the 'at' setting in mtext(.., adj=0, outer=T) may cause the
text to appear in an anomalous position (e. g. in the first
instance below, at the left of the plot region rather than
at 'at=0' in the figure region), or the text may not appear
at all.
If one does not set the 'at' parameter the text appears

"outer" argument in mtext (PR#340)
mtext(..., outer = TRUE) does not seem to center the text in the outer
margins as it did previously. Reproduce with
example(plot.profile.nls, package = "nls")
On versions of the development sources before November 17 this
produced main and subtitles that were centered horizontally on the
page. After that the main title (from mtext("..", side = 3, outer = TRUE))
is centered

outer
i cannot cajole outer in doing what i want it to do.
i hav a function only defined for scalars
fun(n,k)
and i want to do
outer(1:5,1:5,function(x,y) fun(x,y))
(i know this is written somewhat clumsy)
to get an array with the values of fun
to use it as an input for image
this does not work since
outer assumes then fun works on arrays elementwise.
what is the easiest way of getting what i

Using outer with function predict
Hey everybody,
I have a problem with the combination of the commands outer() and predict(). I want to visualize the solutions of a regression modell in a matrix. Therefore I want to use the command predict for a linear modell as the function inside the command outer. I've made a small example:
x = 1:10
y = 11:20
z = rnorm(10)
lm.1 = lm(z ~ x*y)
