[R] problem with vegan function rda()

[Lukas Kohl]

Hello R-list

Maybe someone knows what's going on here.

I'm trying to re-run a script I wrote earlier this year using the function
rda() in the vegan package. The script run fine back then, and I did not
change the dataset, so I was wandering whether there's some problem in a
updated version of the package (I re-installed R + all packages since then).

Thanks for any advice,
Lukas Kohl

So here's the output I get:

> rda(rel)
Call:
rda(X = rel)

Regularization parameters:
NULL

Prior probabilities of groups:
NULL

Misclassification rate:
       apparent:  %
Warning message:
In is.na(x$error.rate[1]) :
  is.na() applied to non-(list or vector) of type 'NULL'

There's no NA's in my dataset, which seems ok..

> sum(is.na(rel))
[1] 0
> nrow(rel)
[1] 59
> ncol(rel)
[1] 49
> head(rel)
