Hello again,
I am still working on variations of the "faithful" example. The last
thing I need to resolve is how to access R lists (and later maybe data
frames) from rpy2 (2.0.8). It seems the following code should allow
access to items in the list returned by the 'shapiro.test'
object/function.
print
print "Shapiro-Wilks normality test of unavailability data"
shapiro_test = robjects.r('shapiro.test')
sw = shapiro_test(uaData)
print "W = %.4f" % sw['statistic']['W']
print "p-value = %.5f" % sw['p.value']
The following is the result:
Shapiro-Wilks normality test of unavailability data
Traceback (most recent call last):
File "D:\Users\roe\Eclipse\workspace\SimPyProjects\src\MachSim01.py",
line 228, in <module>
if __name__ == '__main__': main()
File "D:\Users\roe\Eclipse\workspace\SimPyProjects\src\MachSim01.py",
line 216, in main
print "W = %.4f" % sw['statistic']['W']
File "C:\Python26\lib\site-packages\rpy2\robjects\__init__.py", line
267, in __getitem__
res = super(RVector, self).__getitem__(i)
TypeError: 'str' object cannot be interpreted as an index
If the above does not work, how do I access items in the returned list?
