Dear R people:
I have a vector which runs from -1 to 1, by .1, inclusively.
Easy to set up. x - seq(-1,1,.1)
I then sample 3 numbers from x.
y - sample(x, 3)
Suppose one of my values is -0.7. I want to set up an interval
around that
y1 - pmax(y-0.1,-1)
y2 - pmin(y+0.1,1)
For the value -.7,
the possibilities.

Hi,
I thought this would be close to what you wanted:
x - seq(-1,1,.1)
y - sample(x, 3)
r1 - vector(mode = numeric, length = length(x))
sapply(y, function(k) {
y1 - max(k - 0.1, -1)
y2 - min(k + 0.1, 1)
r1[x = y1 x = y2] - 1
r1
})
but found that it's not replacing 3 elements of r1
