Hi again,<br>
<br>
Mind that looping the pseudo-abs function will overwright the output if you are<br>
not carefull. You need to change the name of the output during the loop, or<br>
store it in a different object before the next step of the loop to keep track of it.<br>
<br>
And yes you're right about the output, it enables to create a new dataframe with <br>
the ones and the selected zeros.<br>
<br>
But I hope you realise that the Models() function has the pseudo-abs function<br>
already inserted in it and deals with the storing issues. You have to use the<br>
NbRepPA argument and the other arguments associated with it.<br>
<br>
Doing a prior run and loading the database created in Initial.State() or setting <br>
NbRepPA to 1 will end up to the same result, unless you wish to run a different<br>
pseudo-abs procedure for each species. To this regard, you do need to do a<br>
prior run.<br>
<br>
Tell me how it goes with the storing issues. Do you need precisions ?<br>

<br>
Apologies for the very late answer.<br>
Maybe you are not looking for the right name.<br>
Look at what you have before and after using the function with ls().<br>
<br>
Mind that it might overwright an existing object, so there will be no difference.<br>
Also try to use the species.name argument. The default value is species.name= 'SpNoName'<br>
<br>
About running the pseudo.abs function on several species at a time, you can only loop the job.<br>
The function does only consider one species at a time.<br>
<br>
Hopîng to solve your troubles.<br>

Hello list members,<br>
<br>
I am trying to run Biomod with several species, and predictors;<br>
I don't know how to get the pseudoabsences for several species at the same time;<br>
In fact, when I try to run the pseudo.abs command with just one species, I can't get the species.name object as the Biomod manual says (Page 75). <br>
Please anyone can send me some thoughts or suggestions to properly run the pseudo.abs function with several species at the sames time?<br>
I want to use this objects in order to run the Models function.<br>
Thanks a lot<br>
Aaron<br>
