Loading C functions into R
Hi everybody,
I have the source of a C program that includes some archives .c and some
libraries .h. I'm developing a program using R and I want it to load the C
program I told before. How can I do that? I was looking for some function in
R to do that and I found the .C() but I can't understand how it works.
Somebody could help me?

Conflict RGtk tcltk
Hi everybody,
I'm making an application using the package tcltk. Everything goes fine until I
load the package RGtk. The interface doesn't work anymore. Is there any conflict
between these packages? I thought about unloading the package RGtk but I don't
know how to do that.
Thanks,

Unload a library
Hi people,
I'm developing an application (in Linux) using tcltk and calling ggobi from that
application (using the Rggobi package). After I load ggobi and want to use the
windows made by tcltk I get some errors and sometimes R cracks. I believe the
problem is because the packages Rggobi, RGtk and tcltk are running together. I
thought about a solution that would be unload the Rggobi and RGtk

is.integer() (PR#6984)
Hello!
I'm not sure if is it a BUG or not...
I'm using R 1.9.0, and I used the command below:
> is.integer(9)
[1] FALSE
R manual contains this words about the is.integer() function:
"is.integer returns TRUE or FALSE depending on whether its argument is of
integer type or not."
What's the problem? Am I wrong about the BUG report?
Thank you very much.

Differential Equations
Hello!
I would like to know if R can solve Differential Equations...
I don't think so because, in my point, I see R like a Statistical System, not a
Math System. Am I wrong?
Thank you very much.
