Hello all,
I spent the weekend experimenting with the faithful.py example at
http://rpy.sourceforge.net/rpy_demo.html. I have made much progress getting
parts of it to work. The following is a summary of issues to date:
1) rpy does not read the two-digit minor release number in the current
version of R. This group informed me of a patch, which I just learned of
this morning. Since I am just starting into the RPy world, I think I will
move forward with rpy2.
2) rpy2 does not appear to understand the following code from the example:
for k in edsummary.keys():
print k + ": %.3f" % edsummary[k]
rpy2 works in a almost complete different way than rpy. You have the read
the documentation for rpy2 and not rpy. Check the documentation for it
here: http://rpy.sourceforge.net/rpy2/doc/html/index.html
3) rpy2 does not deal with the "dot" conversion in the same way as rpy.
This is a big hurtle for me. The "faithful" example uses the following R
objects:
r.dev_off()
r.shapiro_test()
r.ks_test()
There is a workaround for the dot conversion here:
http://rpy.sourceforge.net/rpy2/doc/html/robjects.html#functions
To call objects from the R base package you just need to do the following:
import rpy2.robjects as robjects
phyper = robjects.r('phyper')
shapiro = robjects.r('shapiro.test')
Best,
Bruno
