an easy answer is that hist returns an object which you plot in any way
However, on a more fundamental programming philosophy note, the fact
that R does not allow multiple references to one object is a limitation.
One of the fundamental principles of good programming is that there

Thanks Jim.
I included your suggestion on the script and run fine.
But how can I skip (record X and Y as NULL) on some steps?
On this example it don´t occour, but when working with real data I will need
bypass some acquisitions. Is there a way of do it on a for() looping? I
noticed that if I
Jim,
In fact, if I click stop the for() looping and stop, and I need to
continue on the for().
By other side, is there a way of I ask for the user acquire point (with a
dialog box with Yes or No options), and if the user anwer Yes I collect the
points, otherwise I go for the next step of for()
i have a vector with a string of number
e.g
[1] 0113001 001130011000 001130012000 001130013000 001130016000
[6] 001130018000
i want a vector with the same numbers except with the last three digits of
every factor cut off.
e.g
[1] 01130010 001130011 001130012 001130013 001130016

Hi, basically I am trying to create a grouped bar graph with each group a
different color and a bar in each group to have shading lines. Basically
combine the 2 graphs created below.
Thanks,
Josh
data(HairEyeColor)
a - as.table( apply(HairEyeColor, c(1,2), sum) )
a1-a[1:2,]
par(mfcol=c(1,2),
I tried the add=TRUE but get

Josh,
Check into add=TRUE :-)
All you need to do is insert add=TRUE to the second
chart to superimpose it on the first chart. You might also

Hello everyone,
I am learning about copulas and also do some MATLAB/R coding to get
better understanding of how copulas work.
Recently I have started coding simple copula-GARCH models, that is I
fit say AR(1)-GARCH(1,1)-normal models to univariate time series, and
then I want to fit the copula
Hi,
I would like to convert a character vector
xxx - c(1/2, 1/4)
to
yyy - c(0.5, 0.25)
, but as.numeric didn't work for me. Could anyone give me a hint please?
Thanks,

Hi,
I don't understand why this doesn't work:
matTest - matrix(nrow=3, ncol=3)
testMove - function(I, J){
for(i in 1:I){
for(j in 1:J){
matTest[i, j] - i+j
}
}
}
testMove(2, 3)
matTest
Why the elements of the matrix matTest are still NA? How could I fix it?
In a generalized linear model with k covariates, there are 2(kth power) - 1
possible models (excluding interactions).
