[R] species names on a RDA plot

[Antonio Silva]

Dear R users

I'm trying to do a RDA analysis based on Borcard et al. 2011 Numerical
Ecology with R examples.

What I cannot understand is why when I run the script (RDA.R) using the
dataset from book (dataset1.rar) RDA triplot shows species names and when I
use my dataset (dataset2.rar) species names are not shown.

Data and script can be downloaded at
https://app.box.com/s/oayq7tglbmdsu72fj05h83dlzclsiglg

Does anyone know why this happens? Thanks for any clue.

Best regards
