I have to admit: I don’t like the base R method. In the example below, data from the sample "pressure" dataset is used to plot the vapor pressure of Mercury as a function of temperature. You can also provide row names to the dataframe using row. A numeric vector (or matrix, when beside = TRUE), say mp, giving the coordinates of all the bar midpoints drawn, useful for adding to the graph. Let’s use the dataset chicken which is already included in R. Use the function qqnorm for plotting sample quantiles against theoretical (population) quantiles of standard normal random variable. # simple random sampling in r sample (c ('Good','Bad'), size=6, replace=T, prob=c (. Once the basic R programming control structures are understood, users can use the R language as a powerful environment to perform complex custom analyses of almost any type of data.
