Unable to use multipatt function in indicspecies package

[alison3257]

Trying to excecute Indicator Species Analysis using "multipatt" in the indicspecies package, and I keep getting this:

inv = multipatt(abund, time, func = "r.g", control = how(nperm=9999))
Error in multipatt(abund, time, func = "r.g", control = how(nperm = 9999)) : **
** could not find function "multipatt"

Everywhere I've looked says that multipatt is in this package. What is happening here?

Without a reprex (see the FAQ), all I can offer is the example from the help page

library("indicspecies")
#> Loading required package: permute
## Loads species data
data(wetland) 

## Creates three clusters using kmeans
wetkm <- kmeans(wetland, centers=3) 

## Runs the combination analysis using IndVal.g as statistic
wetpt <- multipatt(wetland, wetkm$cluster) 

## Lists those species with significant association to one combination
summary(wetpt)
