...and have had a terrible time trying to figure out how to set up an analysis.? I have installed and loaded the appropriate package (phyloclim), but I do not even know where to begin defining one of the arguments. The usage for the command I?m trying to perform is: niche.equivalency.test(spec, n, maxent, mx = 2000) where the argument? maxent???? is a list containing the location of the MAXENT application and its input files (see below) >From what I have gathered, the maxent argument is a list of four elements: app????????????? the path to the MAXENT application (MAXENT is a JAVA program)...

Dear all, when using .jinit() I get the message .jinit() : Cannot create Java virtual machine (-1).

Hello, I want to use a for loop for repeadely calculating a maxent model (package dismo, function maxent()) which creates an object of the class maxent (S4). I want to collect all the resulting object in a list. I tried to simplify my for loop to explain what I want. There are two problems/questions: 1) How can I create the new variables in the loop (using paste)...

...to use a permutation test. I've been through CRAN looking at packages boot, bootstrap, coin, permtest, but they all seem to be doing more than I need. Is the following code an appropriate way to test my hypothesis: result.vect <- c() for (i in 1:1000){ wilks <- summary.manova(manova(maxent~sample(max.spec)), test="Wilks")$stats[1,2] result.vect <- c(res.vect,wilks) } maxent is the data, max.spec is a vector of species names. Comparing the result.vect with the wilks value for the unpermuted data suggests there are very significant differences among speci...

Hello! First of all a question: When you make the encoder tables (ie: mode_e.h) do you use the mapping0_forward function? Because you made the encoder tables, and after this you did a minor correction in the final beta4 ... (this correction was: additional[0]=fabs(additional[0]*scale); in the mapping0_forward function) (I see this was a bug, and the modification was correct, but this correction

Hey, I am having troubles using the 'predict' function with in the Raster package. I am using pm<-predict(mm, predictors) where mm is the mahalanobis distance and the predictors are a stack of 6 raster layers containing environmental variables. When I try to run the prediction I get the following warning message: Warning message: In layerNames(x): the layerNames function is

...pt is designed to compare the area of suitable habitat in binary projections of a large number of species current and future distributions, and create an excel file detailing the total area suitable in the present and future scenario, in addition to the area which overlaps. These maps are made from Maxent outputs, which have been reclassified to give binary projections for each species and will be used to assess how climatic change may potentially effect the total area which is suitable for each species. However despite considerable effort I cannot get the attached script to run. It creates an excel...
