qreference {DAAG} | R Documentation |
This function computes the normal QQ plot for given data and allows for comparison with normal QQ plots of simulated data.
qreference(test=NULL, mu = 10, sigma = 1, m = 50, nrep = 5, seed=NULL, nrows=NULL, cex.points=0.65, cex.strip=0.75)
test |
a vector containing a sample to be tested |
mu |
the mean of the simulated reference samples |
sigma |
the standard deviation of the reference samples |
m |
the sample size for the reference samples; default is test sample size if test sample is supplied |
nrep |
the total number of samples, including reference samples and test sample if any |
seed |
the random number generator seed |
nrows |
number of rows in the plot layout |
cex.points |
character expansion factor for plotted points |
cex.strip |
character expansion factor for labels |
QQ plots of the sample (if non-null) and all reference samples
