You can see if your function uses R's random number generator with
the following function.
isRandom <- function(expr) {
randomSeedBefore <- get0(".Random.seed")
force(expr)
!identical(randomSeedBefore, get0(".Random.seed"))
}
isRandom(1:10)
#[1] FALSE
isRandom(runif(3)>.4)
#[1] TRUE
I
You could try this and see what you get:
unique( yguii(ZEEL.NS, "o") - yguii(ZEEL.NS, "o") )
or maybe
table( yguii(ZEEL.NS, "o") - yguii(ZEEL.NS, "o") )
You showed two sets of output from the expression
yguii(ZEEL.NS, "o")
Were they done one right after the other? Or could ZEEL.NS h
Entry 250 is different between the two. However, I (we?) have no idea what that
function is so it might be using randomness as part of its calculation.

Those are function calls, you aren't just printing the same vector
twice, you're producing two

See:
https://cran.r-project.org/doc/FAQ/R-FAQ.html
Can anybody explain me this weird result?
a=3
as.integer(a)
1] 3
a=(3/10)/0.1
a
[1] 3
as.integer(a)
[1] 2
Thank's in advance
