Hola,
Prueba la función scan, después de tu mensaje con cat:
x - scan
Cuando el usuario pulse intro sin introducir ningún valor, tendrás el
vector en el objeto x
Un saludo,

Hi,
DrawDensity3D-function in package VecStatGraphs3D utilizes

You shouldn't be using rgl.points. Use points3d.
The pointsize is a material property (see ?material3d), and isn't a
vector, so you only get one size per

Hello all,
For a study I want to find E|X1/3+X2/3+X3/3-X4| for variables following
lognormal distribution. To get the value we need to use four integrals.
So far, so good.
This is the code which I is used

Recall that List$name is usually equivalent to List[[name]] (2 square
brackets),
not List[name].
Look at names(mi.control.i@data) to see what your paste command
ought to be producing.
Unless the names are important you can use ...data[[j]] to index the

Dear list members,
I'm unable to fit a parametric survival regression using survreg() in the
survival package with data in counting-process (long) form.
To illustrate using a scaled-down problem with 10 subjects (with data placed on
the web):

In solve.QP(), you don't need to expand the equality into two inequalities. It
can DIRECTLY handle the equality constraints. The first `meq' rows of the
constraint matrix are equality constraints. Here is the excerpt from the
documentation.

Well, it's trivial to simulate, and for n=25, for example, I get
a mean of 6.875. Depending on your needs, you can choose a much larger
sample to make it more precise, or, as Chuck suggested, try numerical
integration.
Cheers,

Dear John,
I think you are missing that 'survreg' does not handle left truncated
data. With that you should use the 'eha' package, for a PH model the
function 'phreg', and for an AFT model the function 'aftreg' (you didn't
tell which model you want to fit).
Your attempt with the 'survreg'

i have installed R x64 3.2.2 and i am trying to install annotation software on

Hi Aun,
It looks like you haven't installed the DBI package, which seems to be
required by the hgu133acdf package. Try installing DBI first.

Hi Ramesh,
This may be completely wrong, but did you transfer the R source code files
