PMCMR News

In posthoc.kruskal.nemenyi.test and posthoc.friedman.nemenyi.test the df was set from 1000000 to Inf for calculating p-values of Tukey's distribution.
The vignette was checked for Typos and modified.
The reported chi-square statistics in posthoc.kruskal.nemenyi.test are now corrected for ties.

The function get.pvalues was included to extract the p-values from a PMCMR object or a pairwise.htest object.It can be further processed with multcompLetters from the package multcompView to find and indicate homogeneous groups for a given level of significance.
The functions durbin.test and posthoc.durbin.test were added to test wether k treatments in a two-way balanced incomplete block design have identical effects.
The function posthoc.quade.test was added for multiple pairwise comparisons of rank sums for unreplicated blocked data.
The Jonckheere-Terpstrata test, jonckheere.test, was added as an omnibus test for testing k independent samples against ordered alternatives.
A print.PMCMR and summary.PMCMR was added.
The keyword nonparametric was inserted into each .Rd file.

Title in .Rd-file of vanWaerden.test was changed into van der Waerden's normal scores test.
The formula method for posthoc.friedman.conover.test was disabled, because it does not work.

The van der Waerden normal scores test, vanWaerden.test, as an omnibus test for testing k independent samples for homogeneity was added to the package.
The post-hoc test of van der Waerden, posthoc.vanWaerden.test, for multiple comparisons following a significant omnibus test was added to the package.
The Conover-test, posthoc.friedman.conover.test, for multiple comparisons following a Friedman test was added to the package.
The Conover-test, posthoc.kruskal.conover.test, for multiple comparisons following a Kruskal test was added to the package.
The NAMSPACE file, VIGNETTE and the .Rd files were updated accordingly.

posthoc.kruskal.dunn.test and dunn.test.control were corrected to calculate p-values for a two-sided test.

The Dunn-test, posthoc.kruskal.dunn.test, for multiple comparisons of rank sums was added to the package. Likewise, a Dunn-test for multiple comparisons with one control, dunn.test.control, was added. The NAMSPACE file, VIGNETTE and the .Rd files were updated accordingly.

The examples in the LaTeX document (vignette) were corrected. The help pages were extended.

A formula method posthoc.kruskal.nemenyi.test.formula() and posthoc.friedman.nemenyi.formula() was added to the code in a similar fashion as it is coded in kruskal.test and friedman.test of the package stats. The NAMSPACE file and the .Rd files were updated accordingly.
