Greetings,
I've been struggling for some time with a problem concerning a big database
that i have to deal with.
I'll try to exemplify my problem since the database is really big.
Suppose I have the following data:
AA = c(4,4,4,2,2,6,8,9)
A1 = c(3,3,5,5,5,7,11,12)
A2 = c(3,3,5,5,5,7,11,12)
A = cb

Thank you Brian.
Sorry for being such a noob. I am not a programmer and just learning R by
myself. This is was I typed, but ended up with a couple error messages.

I am trying to create a plot that has multiple plot characters for
each point (e.g. a point within a triangle, a triangle within a
square, etc). The workaround I have found to do this is by plotting
twice, as in this example:
x <- c(1.1, 2.3, 4.6)
y <- c(2.0, 1.6, 3.2)
plot(x, y)
points(x,y, pch=2
Thanks! It was easy to solve, then... I just hadn't considered that.
For the record: I've never actually taken statistics, so I'm learning it at
the same time as R. So yes, this is a private project.

The key to this is the grep() command.
It's easiest if you import your data as character rather than factor,
since these aren't properly factors. You don't say how that's done,

conversion to factor.

How can I adjust this path. My current path of Graphviz installation is:
C:\Program Files (x86)\Graphviz2.20\bin
and Rgraphviz is
C:\R\library\Rgraphviz\libs\i386
Please help me. I am new to Rgraphviz.

Dear all,
I am trying to use the np package for the estimation of a model with Klein
and Spady's semiparametric estimator. When though, I include a constant term

Hi Martin,
Off hand I do not know of a pre-defined function to do it, but the
"z-transformation" is just the inverse hyperbolic function, the mean
is just the mean, and the back transformation is the hypoerbolic
function so...
x <- c(.5, .4)
tanh(mean(atanh(x)))

Dear Johannes,
because myFun has an environment, and that the global environment. Look at:
with(myEnv,
{
myFun2 <- function(symbols){do.call("print", lapply(symbols, FUN=as.name))}
do.call("myFun2", list(symbols.env))
do.call("myFun", list(symbols.env))
})
Also, for example, compare
While you study the documentation as others suggested, may I suggest that you
take a look at the
file.exists()
function. Here is an example of using file.exists().
tmpfile <- define()
if (file.exists(tmpfile)) {
## read the file
} else {
## tell the user to try again
}

Hi,
is there a function in R that computes the mean of two (or more) correlations?
(that is doing the z-transformation of the correlations, computing the mean of
the z-values and then retransform it to a correlation).
Or is there a fisher-table implemented?
I have not found anything via help.

Or use ‘format’ in R. Example:

Dear list members,
I’m looking for a way to divide numbers into simple (i.e., integer-valued)
intervals, and thought the ‘cut’ function in ‘base’ or the ‘cut2’ function
in ‘Hmisc’ would, er, cut it. However, they seem to give rather surprising
results.
Since I want the endpoints of the interva

Hi everyone
just a brief question:
I'm trying to perform a smallest space analysis on nonmetric variables with
R.
It seems there are at lear a couple of packages to perform non metric MDS
but still not found any info concerning SSA.
Any clue?
thanks in adv.
