Function to plot probability plots
Description
probplot
plots probability plot for a vector of values, given distribution specifications. Confidence intervals and a legend can be plot too.
Usage
probplot(x, distribution, theta, confintervals = FALSE,
confidence = 0.95, name = deparse(substitute(x)))
Arguments
x |
a vector of values. |
distribution |
character specifying distribution to plot |
theta |
vector of parameter. Estimated by the function if left missing |
confintervals |

confidence |
confidence |
name |
name of variable plotted. |
