I'll report that at least theme_set etc is missing from the static lib. >> In R, I would just type 'pp' at >> the prompt to show the plot.

Maybe I'm missing something basic. I've read and reread the rpy-list thread at http://www.mail-archive.com/rpy-list@lists.sourceforge.net/msg01665.html entitled "how to pass a python object to R". import rpy2.robjects as ro gg=importr("ggplot2") ... # generating data #plotting pp=gg.ggplot(datafhist)+gg.aes(x='z',y='..density..') pp+=gg.geom_histogram(binwidth=bw) pp+=gg.geom_line(gg.aes(x='z',y='dens'),data=datafline) pp+=gg.scale_x_continuous("z position") pp+=gg.theme_set(gg.theme_bw()) >>> ro.globalenv['pR1']=pp >>> ro.r['pR1'] <Vector - Python:0x101c47518 / R:0x101d8ff80> >>> ro.globalenv['pR2']=ro.conversion.py2ri(pp) >>> ro.r['pR2'] <Vector - Python:0x101c47c68 / R:0x101d81d80> >>> print(ro.r['pR2']) $data ...contains all the ggplot2 items I'm not sure what's going on here. Is the object supposed to be a Vector? For the static lib, it ended up being a GGPlot.
