Package: python-rpy
Version: 1.0~rc3-2
Severity: normal
On an amd64 system, run following script:
from rpy import *
x = r.seq(-10, 10, length=60)
y = r.seq(-8, 8, length=60)
f = r('function(x,y) { r <- sqrt(x^2+y^2); sin(r)/r }')
z = r.outer(x, y, f)
r.png("image.png", width=480, height=340, bg="transparent")
r.persp(x, y, z, theta = -15, phi = 35, expand = 0.5, col="#b0b0d0",
axes=False, box=False)
Instead of generating image.png, this will generate the following output:
RHOME= /usr/lib/R
RVERSION= 2.6.0
RVER= 2060
RUSER= /home/user
Loading Rpy version 2060 .. Done.
Creating the R object 'r' .. Done
Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf
Traceback (most recent call last):
File "persp.py", line 9, in ?
col="#b0b0d0", axes=False, box=False)
rpy.RException: Error in persp.default(c(-10, -9.66101694915254,

invalid 'z' argument
I tried downgrading the version of python-rpy on amd64 and the script executed
without
generating the error in versions up to and including python-rpy 1.0~rc2-1 with
r-base-core
version 2.5.1-2. The error first showed up in python-rpy 1.0-rc3-1 on amd64.
I also tried this on i386, and as far as I can tell, this error does not show
up in any version
under i386.
