Hi,
You cannot start with a "*" in expression(). Try this,
plot(x~y,ylab=expression(~degree~C))
or even, as a short-cut,
plot(x~y,ylab=~degree~C)

Thanks for that again. That almost works, except that lines are drawn

Hi,
I need to get a character vector from an object of class call. But
using as.character() returns something based on the internal structure
of the object, and not, as I would like, some akin to the output of
show() on a call object.
Any idea on how to obtain the same output returned by show?

Hi,
Does anyone know where the following package is available:
Holleczek B, Gondos A, Brenner H.
PeriodR - an R package to calculate long term survival estimates using period
analysis.

Dear All!
I have a few question about proper syntax for fuzzy rules in sets
package (there is only little help about it):
1) how to use negation (NOT) operator there is only OR (||) in example
it is NOT, !!, !. I also assume that AND is &&
2) where it can be set. For example:
area %is NO
Try this:
y <- function(a)
substitute(a * x, list(a = a))

Hi Zemajik,
Try this:

Also, take a look at the Ryacas package.

Hey,
I'm trying to find how to perform operations with a variable treated as a
symbol.
For, an extremely simple, example I want to integrate a*x with respect to x
and I want to find the indefinite integral of this, (a*x^2/2), or the
definite integral with some interval for x.

Dear All,
Here is what I am trying to achieve: I would like to plot some data in 3D.
Usually, one has a matrix of the kind
y_1(x_1) , y_1(x_2).y_1(x_i)
y_2(x_1) , y_2(x_2).y_2(x_i)
...
y_n(x_1) , y_n(x_2)..y_n(x_i)
where e.g. y_2(x_1) is the v

i was not aware of str, i have a very large code since i am new to r.
I forgot to mention that the package is sampling. Actually i have this
simulated code:
n <- c(100,400,1000,1500,2000)
x <- c(2,3,3,3,5)
y <- c(7,7,9,10,10)
s <- function(mn, mx, n) {sample(mn:mx, n, replace=TRUE)}

I can't determine what is going on in you example, but my approach would be
to read the text file into a text editor that will display hidden characters
(tab, etc.) so you can see the pattern. It could be that there is an extra
tab in some locations. You could then use the editor's replace functi
