dear all- If I have a vector of numbers (not necessarily normally distributed) how can I get the p-value of a number in this distribution. I am interested in the "inverse" of 'quantile' . thank you- Maya
I'm not sure whether I got the point, but my guess is that you are trying to count how many observations in a vector x have values less than a and divide by the total number of observations in x, e.g.:
x <- rnorm(20) a <- 0 sum(x < a) / length(x)
