Plotting p values in r

WebPlot function in R. The R plot function allows you to create a plot passing two vectors (of the same length), a dataframe, matrix or even other objects, depending on its class or the input type. We are going to simulate two random normal variables called x and y and use them in almost all the plot examples.. set.seed(1) # Generate sample data x <- … WebDescription. QQ plot of observed P-values vs expected P-values, using the empirical (permutation-based) expected p-value distribution. This empirical-based expected p-value distribution no longer depends on an assumption that the Fisher's Exact two-tailed p-values are uniformly distributed under the null.
