Hi,
I've noticed something strange when using the terms {stats} function.
R documentation describes the factors attribute of the terms.object as follows:
A matrix of variables by terms showing which variables appear in which terms.
The entries are 0 if the variable does not occur in the term, 1
I ran into this and found the result very surprising:
identical( quote({ a }), quote({ a }) )
# FALSE
It seems related to curly braces. For example, parens work fine:
identical( quote(( a )), quote(( a )) )
# TRUE
Is this expected behavior? I can't seem to find anything in the help

Fascinating! I tried the comparisons with all.equal(), expecting a
description of the difference, but TRUE was returned in both cases.

for identical that relates to this.
It's not in ?identical, but ?Paren gives you some pointers.
str(quote((a))) and str(quote({a})) are also informative.
Yes, looks like srcrefs are to blame:
x - quote({ a })
y - quote({ a
Ah, I was using identical() to compare two function bodies. It returns
FALSE even when you remove srcrefs from the body:
f1 - function(x) {
if (TRUE) { x }
}
f2 - function(x) {
if (TRUE) { x }
}
f1b - body(f1)
f2b - body(f2)
attributes(f1b) - NULL
attributes(f2b) - NULL
# The bodies look the

Greetings,
When I try install.packages('Rcpp') it fails when compiling api.cpp (line
39). This is Rcpp 0.11.3. I searched my filesystem, and indeed I do not have
execinfo.h anywhere. After some effort, I got R build on AIX. Now I am trying
to build the packages I need. Rcpp is crucial.
