Smart use of "$".
Other possible way:
summary.r["sigma"][0][0]

It gives the names of the components.
Consider the following example:
import rpy2.robjects as ro
fit = ro.r["lm"]("%s ~ %s" %(ro.IntVector([1,2,3]).r_repr(),
ro.IntVector([3,1,2]).r_repr()))
sfit = ro.r["summary"](fit)
elt = [sfit[i] \
for i,x in enumerate(ro.r["names"](sfit)) if x == "sigma"]
# and yet another way to get "sigma".
elt[0]
