Thank you. I'll send you unit tests for both "as" and "const ctor".

Right. I see what you mean. If it does bot disturbe anything else, i should be
able to bring it back.

The former:

And proceeds to do so with a one-liner :)
Thanks for putting the fix in.

To be more precise, it was introduced after 0.10.0 and before 0.10
The version assigning an element of a const CharacterVector to a const
std::string (named "bar" below) compiles and works fine in Rcpp 0.9.14,
so the problem was introduced after that.
On the other hand, "as" (function "baz") fails as in
0.10.2, probably for the same reason Kevin identified in
Perhaps this will narrow down the 'why as seems to fail'. I'm looking at
the Rcpp 0.10.2 source. (hopefully I've got this right):
Rcpp's 'as' uses ::Rf_isString to check whether the item passed is a
string; or more specifically, a STRSXP. However, elements within a
CharacterVector seem to be of 't
I tracked this down to const-ness:
bar <- cxxfunction(signature(xs_="character"), plugin='Rcpp', body='
const CharacterVector xs(xs_);
const std::string x(xs(0));
Rcout << x << std::endl;')
fails with the compile error mentioned in my last message, while
foo <- cxxfunction(signature(xs_="charact
Davor, Kevin,
Allow to get into this intra-Vancouver exchange as I too dislike the sound of
"but this used to work"
A simple modifcation (see below) seems to do the trick:

R> getString(c("The", "quick", "brown", "fox"), 2)
[1] "brown"
R> getString(c("The", "

Hi Davor,
One trick to get around this is to 'as' the entire CharacterVector into a
std::vector< std::string >, and then index based off of that.
My guess is though, elements of CharacterVectors are 'const char*' s, so to
convert them to strings you might want to just use std::string constructor,
I have a CharacterVector from which I try to extract an element and assign it
to a std::string:
CharacterVector xs;
...
std::string x = as(xs(0));
This throws exception: "expecting a string". Why? Looking with the debugger at
"xs", this is what I see:
(gdb) print xs
$6 = (CharacterVector &) @0
15 matches
