from rpy import r
import Numeric
r.png('output_r_test.png')
bars = Numeric.array([[25,15,26,25,18],[45,32,28,12,45]])
print bars
r.barplot(bars, beside = "TRUE" )
r.dev_off()
Gives the following output:
[[25 15 26 25 18]
[45 32 28 12 45]]
Traceback (most recent call last):
File "r_test.py", line 70, in ?
r.barplot(bars, beside = "TRUE" )
rpy.RPy_RException: Error in -0.01 * height : non-numeric argument to binary
operator
My question is: the array "bars" looks to be all numeric to me- so what does
this error mean?
I am using Python2.4.1, R-2.7.0 on a windows platform.
Thanks in advance.
