WebThis is referred as normal distribution in statistics. R has four in built functions to generate normal distribution. They are described below. dnorm (x, mean, sd) pnorm (x, mean, sd) qnorm (p, mean, sd) rnorm (n, mean, sd) Following is the description of the parameters used in above functions −. x is a vector of numbers. WebGenerates a probability plot for a specified theoretical distribution, i.e., basically a qqplot where the y-axis is labeled with probabilities instead of quantiles. The function is mainly intended for teaching the concept of quantile plots.
