Indeed, I misread / misunderstood. I think it's a difficult concept that's hard
to explain and the example wasn't great. But thanks all for straightening me
out!

According to
http://cran.r-project.org/doc/contrib/Fox-Companion/appendix-scope.pdf and
other examples online, I am to believe that R resolves variables using lexical
scoping by following the frames up the call stack. However, that's not working
for me. For example, the following code, taken
Anyone have a clue why assigning to a list field in a RefClass is so much
slower than assigning to a plain old list?
For example, given a list of length N, if I want to assign a value to each
entry, then the running time is quadratic in N.
That is, refclass$a.list[[i]] <- value is much much slowe

You have an extra space in the INFECTION factors.
Use REC2[REC2$INFECTION=="Infected ",]
or
subset(REC2, INFECTION=="Infected ")
No need to use which here.

I'm using refClass for a complex multi-directional tree structure with possibly
100,000s of nodes. The refClass design is very impressive and I'd love to use
it, but I've found that the size of refClass instances are very large and
creation time is slow. For example, below is a RefClass and no

I'd like to write unicode strings using the "\u" escape syntax. According to
the documentation, print.default or encodeString will escape unicode using the
\u convention. In practice, I can't make it work.
