<p class="MsoNormal"><span lang="EN-GB">Dear R-forge-List,<br>
<br>
I'm using the package biomod to identify areas of potential distribution of a
butterfly. I don't have independent data to test, so I'm using a partition of
the data 80/20. Maybe I should say as well that I chose to run the Models with
only 1 repetitions but 2 runs of Pseudo-absences, and also that I'm running this models under R-2.9.2 linux. But I have also tried to run it under windows R-2.11. (without much success because of the memory limit issue)<br>
<br>
I have 4 questions.<br>
1. In the tutorial for this package is described the function level.plot. It is
useful to plot the results of every model but in the tutorial they ran the
Models with "independent data", Is there any possibility to use this
function without having to run the models with independent data?<br>
<br>
load("pred/Pred_Ag_cing")<br>
level.plot(Pred_Ag_cing[,"RF",1,1],coorxy,title='Ag_cingulata RF')<br>
<br>
Error in level.plot(Pred_Ag_cing[, "RF", 1, 1], coorxy, title =
"Ag_cingulata RF") : <br>
<br>
data and coordinates should be of the same length <br>
<br>
length(coorxy$Longitude)<br>
[1] 2697182<br>
<br>
length(Pred_Ag_cing[,"RF",1,1])<br>
[1] 1350<br>
<br>
It gives me an error saying that the coordinates and the data must be the same
length, (the truth is I don't get why without running the models with
independent data it doesn't get the same length but with independent it does.) <br>
<br>
<br>
2. Is there any possibility to export the data to make<br>
the plots as an ascii files so can be imported into GIS? I know there is the function Projection.raster (under windows R.2.11) but when I try to imported into GIS it doesn't show anything (does it also exist in Linux?) <br></span></p><p class="MsoNormal"><br><span lang="EN-GB"></span></p><p class="MsoNormal"><span lang="EN-GB">3. When using Projection.raster function, it doesn't produce the output that the functions Ensemble.forecasting and ProjectionBestModel requires to work. But if I use the function Projection is not possible to export them as ascii files. Is it true?, Is there anyway to solve this? <br></span></p><p class="MsoNormal"><span lang="EN-GB"><br></span></p><p class="MsoNormal"><span lang="EN-GB"><br></span></p><p class="MsoNormal"><span lang="EN-GB">
4. If the only way to plot the outputs of the models in GIS is by extracting the
model and using Raster <span class="yshortcuts"><span id="lw_1276088743_0">Calculator</span></span>, how do I get the final models of RandomForest, MARS and GAM?<br>
<br>
Any help would be very much appreciated, <br>
<br>
Thanks a lot in advanced,<br>
