Re: [maxent] How to extract data for response curves?

[Bede-Fazekas Ákos]

Dear Niza,

you should pass the "writePlotData=true" parameter to the Maxent.jar to force saving output files containing the data used to make response curves. Then, you can load these data to any software (e.g. R) and plot them (e.g. by ggplot). I think this can be achieved by
ENMevaluate(occ, env, writePlotData = "true")
or
ENMevaluate(occ, env, "writePlotData=true")
, but I'm not familiar with ENMevaluate(). If you use package 'dismo', it works like this:
maxent(x, p, path, args = "writePlotData=true")

Hello group,

Is there any way to create response (get output data and save data frame) plots in ggplot2  (get output data and save data frame)? I am using the R package ENMevaluate .

Thank you so much, all the best,

Niza

Hello Niza,

Your suggestion did not work for me in ENMeval but I found how to do it in this link:

https://github.com/jamiemkass/ENMeval/issues/104

You just need to select the model and the variables you are interested in via dismo::response and convert the plot to a data frame. Here is an example of what I did.

best_model<- allmodelsfromenmevaluate@models[[10]]

rainfall_rc_df<-as.data.frame(dismo::response(best_model,var=rainfall))

I did not find how to do all variables at once though, but this could be good enough.

Hopefully, this works for you as well.

Cheers,


Ione
