R help - Apr 2015 - species names on a RDA plot

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

Hello everybody

The problem is that species names are shown in the ordination diagram when
the data set has a maximum of 80 rows, and mine has 81 (!!!).

So now the question is: it is possible to go through this limitation?

Thanks again,

Ant?nio Olinto

Hi Antonio,
Is it possible to use "add=TRUE" and display the plot in two passes?
