It looks like you are attempting to divide a number by a formula.

Hello,
Try
C*as.integer(factor_classes)
And note that you don't need the loop.
Hope this helps,

Write yourself an alternative function to table, for example like this:
tableOfGivenLevels = function(x, levels)
{
n = length(levels)
counts = rep(0, n);
names(counts) = levels
tab = table(x);
counts[match(names(tab), levels)] = tab;
counts;
}
x = sample(c(1:4), 20, replace = TRUE)

Yes, I think that is the problem, thank you.
How would I write the code to include 0s in the matrix,
ie, I want to have a record of when 1, 2, or 3 does not get sampled,
to come up with a frequency of e
Not sure ho to run the code since nn is not defined.
Most likely reason is that the number of unique values in the rows of
habs is not the same. That makes the tables produced in the apply
command of different length and apply returns a list instead of a
matrix, which makes the t() or the division

Thank you everybody for the help! The solution of my problem is here:

Hi,
Well, I did it, but all my script was on the first message. I don't have any
other variables. I am just reading a NCDF file and trying to read the
variable "tasmax", that has values of temperatures.
The only "new" information I have is the header of the NCDF file
(Spain02D_tasmax.nc), that I
Thank you for your answer, Jim! I will try it and post what I find.
cheers,

There are several references on how to use the debugging tools in R

hi: it's not clear to me what you're trying to do but maybe outer is
what you want ?
outer(x,y)
it takes every value in x and pairs it with every value in y and the
default operation is multiply. see details by doing ?outer.

Hi,

I'm not sure what you are trying to do: modulo arithmetic isn't exactly
splitting a matrix into 2. Or even remotely.
Regardless of the goal, when numbers are shown in quotes, it's a sure
sign that R thinks they are strings, and thus non-number, just as the error
message (not a warning) states.
