Do you get any errors? I am not too familiar with RTAQ, but I am not
seeing aynthing you are doing obviously wrong. Another possibility I
guess is that R may not have write permission to the datadestination

Hi,
That seems a reasonable enough approach to me.

is the probability of a value being less than or up to 0 from the
distribution you specified. Using that, lets repeat your little test

To open a graphics device, you usually use a function like png() or
eps() then do your plotting then dev.off() to close it when you're
done.
Sounds like you need something like hist(x, breaks = 100, freq = TRUE)
Hope that helps,

Hi,
I want to compute p value of sign test for sample size=15 from normal
distr., sd=0.5, mean=1, alternative should be two sided.
Is this code correct in this situation?
binom.test(sum(rnorm(15,1,0.5)>0),15,p=0.5,alternative="two")$p.value
Or should I use another code (function) e.g. rbinom?

Your problem is not well-defined. In your example below, why not
remove rows 1,2,6, and 10, all of which contain NA's? Is the matrix
supposed to be symmetric? Do NA's always occur symmetrically?
You either need to rethink what you want to do or clarify your statement of it.
