Dear R People I have a variable which is an ID number that is a factor. I would like to look for ID numberbs that are greeater than a particular value.

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 interval will run from -.8 to -.6. There will be several intervals.
