Rcmdr menu interface to plot the qqplot of variable against one of the following distributions: normal, t, chi-square, F, other.

1 |

The `normal`

gives the option to do the Shapiro-Wilk test of normality.
The `other`

requires you to specify the distribution.
Any distribution for which quantile and density functions exist in
R (with prefixes `q`

and `d`

, respectively) may be used.

`NULL`

. These functions are used only for their side effect (to
make a graph).
