Hi,
I am drawing several plots and want to have italics in a main title;
this is easy with expression(). However, I want also to add a value to
it, say n_i, that depends on an ith plot. For this I am using paste().
An example: n_i = 10, 20, 30; I want to draw a plot for each i with
the title:
[EMAIL PROTECTED]:
p0- c(f=0.87, b=0.1, c=150)
f-p[1]; b-p[2]; c-p[3]
Do *not* redefine the meaning of the function c() to 150, or to p[3].
If you do, very few things in R will continue to work properly!

Here is an alternative approach to saving the itterations:

ms.mat - matrix(nrow=0, ncol=2)
f1 - function(ms, data){
ms.mat - rbind(ms.mat, ms)
-sum( dnorm(data, mean=ms[1], sd=ms[2], log=TRUE) )
}

An alternative way to draw the symbols (or some approximation of them) is to
use the my.symbols function from the TeachingDemos package along with ms.male
and ms.female (or your improvement of these, also from the TeachingDemos
package). See the 4th example from ?ms.male (or ?ms.female).

This is likely an stupid question, but I cannot find the solution.
I am searching for an exit function, to end the execution of an R

Any clue?

I have a script that contains ~ 10,000 lines of code. Most of it is
written as small functions. However, for various reasons, the final
function is ~1500 lines of code. I realize that this may not be
optimal but the code evolved that way and breaking it into smaller
pieces

Hi the list.
I got a probleme with R CMD check. I run a package.skeleton on a very

I would like to set up a Windows XP environment with R and MySQL.
This set-up was recommended by a friend who uses this set up, but I
have been unable to get RJDBC to work. I have installed all of the

versions of software.

Hi,
If there are more than one item having the same value, how can i use R to
take the average of the position. E.g:-
X Y Z
131 22.2 3.4 4.4
132 20.0 3.4 4.4==Position 2 if queried
150 20.0 12.2 4.5 =Position 3 if queried
134 20.0 3.4 4.4 == Position4 if queried
159 20.0
I can't comment on problems with RJDBC but I can say that if you want to
access MySQL from R, I have had very little difficulty doing it with
RODBC. The only difficulty I have experienced is in getting the MySQL 5.0
server started, which after hours of trying I avoided by using MySQL 5.1.
Thanks for the above mentioned methods. I will try them one by one.
Thanks again.

Is there anyone have some experience in the boost package. I used the

This is the format I used.
