The warning (with an error you would not see any results) means that there are
ties in your data, the theory behind the ks test says that the probability of
seeing ties is 0, so your data and the theory do not match, therefore the
p-value is suspect (though an ok approximation for some uses).
It is not clear what question you are trying to answer. Perhaps if you can
give us an explanation of your overall goal then we can be more helpful.

Hi David,
I would like to apologize for what I wrote earlier. It was late and I
was frustrated. Please give me time to adapt to the formal structures
of the forum.

Thank you, you're right. I should have read the website more carefully:
Download and install R (installers for Linux, Mac OS X universal, Windows,

In Windows, I use that version but I didn't think about it when

Thanks for the help so far-- one interesting thing about this particular page
is that the data displayed on the website actually differs from the data you
can access with the download link. The XML package command works, but the

Suppose
x - array(c(1,1,1,1,2,2,2,2), dim = c(2,2,2))
y - c(5, 10)
Now I would like to multiply x[, , 1] with y[1] and x[, , 2] with y[2].
Possible solution is a for-loop:
for (i in 1:2) {
x[, , i] * y[i]
}
Another possible solution is this construction:

I run a loop wrapped in try(), and for each of the rows where
try-error is true I want to fill that row with NA (at the moment it is
omitted). So I would expect to get a dataframe with 1000 rows some of
which would be empty, but instead I get a dataframe with 995 rows. In
