[R-sig-Geo] hist() in raster package

[Agustin Lobo]

Robert,

I'm using
 > packageDescription("raster")
Package: raster
Type: Package
Title: Geographic analysis and modeling with raster data
Version: 0.9.9-14
Date: 8-Febrary-2010

(Maybe I should wait few more hours to get the fixed version?
The date above seems earlier than your message, but just to let you
know in case this is a really pending issue, as you were mentioning 0.9.9-14)

on a linux machine now and still have problems
 > a <- hist(r,plot=F,maxnsample=100)
 > a
NULL

also, the graphic window gets opened although
no graphic is plotted.


Thanks for you help.

Agus
