aboot and custom distance

[Chiara Delvento]

Hi,

I'm trying to use aboot with  the WardD2 method and a custom IBS matrix as distance.

Therefore: 

1) I've used the DART package to create the function for the IBS distance, which requires the genelight input format and creates a "dist" object as output.  

2) I used this function in the aboot analysys but I've this error:

"Starting Error in cat("Starting", funname, "\n") : 

  argument 2 (type 'language') cannot be handled by 'cat'"

Here is my script

library("poppr")

library("dartR")

data("nancycats")

nancy_light<-gi2gl(nancycats, parallel = FALSE, verbose = NULL)

wardd2 <- function(d) ape::as.phylo(hclust(as.dist(d), method = "ward.D2"))

ibs_dist<- function(i) (dartR::gl.grm(dartR::gi2gl(i), plotheatmap = F, verbose = NULL))

tree <- aboot(nancycats, cutoff = 0, tree="wardd2", quiet = TRUE, sample = 100, distance = ibs_dist)

Thank you in advance,
Chiara.
