[Rcpp-devel] multidimensional arrays

[Frederico Mestre]

Hello all:

 

I'm a regular user of R, but my knowledge of C++ is limited. 

 

I need to create functions to generate random landscapes (with two habitat
classes) based on area and distance amongst patches. This would take quite a
long time in R so I thought it would be better to use Rcpp (which seems a
simpler way to integrate R and C++). I need to generate these landscapes for
the current time and their evolution in the future (about 1000 to each of
these time steps).

 

I thought it would be better to generate these "landscapes" as
multidimensional arrays but I'm finding it hard to work with C++.

 

Would it be adequate to use this functions:

 

rdlandscape <- cxxfunction(signature(x = "numeric"), body = "C++ code",
plugin="Rcpp")

 

I don't need to retain these objects after the run just calculate several
parameters (as extinction probability) of a species that would be present in
these landscapes.

 

Any ideas?

 

Best,

Frederico Mestre
