Finance::YahooQuote 0.24

Having espoused rule number one in regression testing in the post about yesterday's bug fix upload 0.23, we can now add rule number zero: Do not introduce a new error by omitting the trailing semicolon. I guess it shows that I don't really program in Perl anymore.

Anyway, a new version 0.24 of Finance::YahooQuote which addresses the issue that required upload 0.23 yesterday is now in the Debian queue and on CPAN and my local yahooquote page. This time it may even work. A big thanks to the CPAN Testers for getting me reports on this one too.

Rcpp 0.7.11

A new versions 0.7.11 of Rcpp is awaiting inclusion into CRAN and Debian. It is also available from here.

This version fixes a somewhat serious bug uncovered by Doug Bates when working with vectors of strings. We also added a few new accessor functions as well as a new convenience function create that is particularly useful for creating (possibly named) list objects that are returned to R.

Here is the full NEWS entry for this release:

0.7.11	2010-03-26

    o	Vector<> gains a set of templated factory methods "create" which
        takes up to 20 arguments and can create named or unnamed vectors.
        This greatly facilitates creating objects that are returned to R. 

    o	Matrix now has a diag() method to create diagonal matrices, and
        a new constructor using a single int to create square matrices

    o	Vector now has a new fill() method to propagate a single value
    o	Named is no more a class but a templated function. Both interfaces
        Named(.,.) and Named(.)=. are preserved, and extended to work also on 
        simple vectors (through Vector<>::create) 
    o	Applied patch by Alistair Gee to make ColDatum more robust
    o	Fixed a bug in Vector that caused random behavior due to the lack of
        copy constructor in the Vector template

As always, even fuller details are in Rcpp Changelog page and the Rcpp page which also leads to the downloads, the browseable doxygen docs and zip files of doxygen output for the standard formats. A local directory has source and documentation too. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page
