Error in loadNamespace(name) : there is no package called ‘dunn.test’

[Epigouveia]

Hello FSA makers,

I just installed FSA to run a dunnTest on my data after a Kruskal analysis. When I run the function dunnTest I get a message saying Error in loadNamespace(name) : there is no package called 'dunn.test'

Can you help or guide me on how I can solve this?

Here is what i have installed:

install.packages("FSA")
if (!require('devtools')) install.packages('devtools'); require('devtools')
devtools::install_github('droglenc/FSA')

Here I try to run the test: DunnT_d10 <- dunnTest(mtdt_d10$richness ~ mtdt_d10$Treatment, method = "bh"

Where mtdt_d10 is my df with richness as a column. the column Treatment is the type of grouping I want. Below my data

> mtdt_d10

Thank you Epigouveia

Epigouveia,

For some reason, it appears that the dunn.test package has not installed on your system. You should be able to install it with ...

install.packages("dunn.test")

Let me know if that solves your issue. Thanks.

Hi droglenc,

I did also installed the package dunn.test and was able to run the function dunn.test. So yes it did work So now I have two different packages for the Dunn Test. Is the FSA and dunn.test linked?

Best

Yes dunnTest from FSA is a wrapper for dunn.test from the dunn.test package. The FSA version has a slighty different interface and set of defaults. This is described in the dunnTest documentation (see the Details section).
