I would be gratefulf if anybody can help me with this problem. I have not
a experience with R
language, actually this is my first job with it :
I have write some instructions for acomplish a simulation, and I have 36
conditions
with 1000 iterations each one . The program runs without problems, but in
the 19 nth
condition gives and error message (after running some iterations of
this condition)
is:
"Error in var(x, na.rm = na.rm) : missing observations in cov/cor"
Somebody would give me any clue about the origin of this error?
There is any probability that the origin of the problem is the scarcitie
of resources?
( I don?t understand how is possible a programming error).
Any help will be welcome.

So, presumably by former calculations, you got NAs in some data structure for which the variance is calculated. You have to debug your code, if you don't know where the NAs come from. Uwe Ligges

This is unlikely to be due to a scarcity of resources; that should give a different error message. What the message says is that at some point you (or a function you call) are calling the var() function and passing it NA values where it doesn't want them. You can use the traceback() function after the error to see where the call occurs. If the NA values should be removed, then you need to make sure that na.rm = TRUE when this call occurs. If the NA values shouldn't be there, then you need to find why they are, and fix your code. Duncan Murdoch
