When I try to run a dissimilarity analysis using the vegan library in Pythonwin
calling to R I seem to get into a situation that I can only describe as
stalling without any error generated. I can run the exact process in R
directly and it runs fine, and I would like to set this up as a tool from
ArcGIS.
This is a pretty simply process, below is the example scripting. When I run
the process from Pythonwin it makes it to the last line in then just processes,
I've let it run over 6 hrs and there seems to be no progress, but the cpu and
ram and being actively utilized. If I run it directly from R it's done in a
less than a minute.
import rpy, win32com.client, numpy
from rpy import r
r('library(vegan)')
r('csv <- read.csv("c:/Projects/Brazil/Analysis/CSV_Crosstab.csv", header=T,
as.is=T)')
r('dim(csv)')
r('names(csv)')
r('csv.data <- csv[,c(-1)]')
r('csv.m <- as.matrix(csv.data,)')
r('dimnames(csv.m) <- list(csv$site_id, names(csv.data))')
r('csv.dis <- vegdist(csv.m, method="jaccard")')
Any help would be appreciated, without an error I'm at a loss as to what to try
to trouble shoot.
Thanks,
Jon
