[adegenet-forum] error in hclust

[Mark Coulson]

Ok,

So got it working now by omitting the D <- as.matrix(X) step and running the hclust only from the D <- dist(X)

Odd indeed. Are there any NAs in 'X'?

Cheers

Hello,

Yesterday I ran  the following code and everything worked just fine. Today I simply opened up my script and re-ran it and got the following

laidon <- import2genind("laidon_project_data_no_sibs.str")
X <- tab(laidon, freq=TRUE, NA.method="mean")

D <- dist(X)
D <- as.matrix(D)

h1 <- hclust(D, method="complete")

Error in if (is.na<http://is.na>(n) || n > 65536L) stop("size cannot be NA nor exceed 65536") :
  missing value where TRUE/FALSE needed

Not sure what this error means but more confused as to why suddenly it isn’t working. Nothing else has changed
