Subject: [R-pkgs] solaR: version 0.20


Hello,

I'd like to announce the availability of the version 0.20 of the
"solaR" package. It provides a set of calculation methods of solar
radiation and performance of photovoltaic systems. The package has
been uploaded to CRAN under the GPL-3 license.

The most important changes included in this version are:

*The package is now almost entirely designed with S4 classes and
methods.
*The time series objects are constructed with the 'zoo'
package.
*Most of the functions and arguments have been renamed in
order to ease the understanding by international users.
*Two new functions have been included for the statistical analysis of
a PV plant composed of several systems.
*The package dependencies have been optimized.
*Several new small functions for date-time calculations are now
available.
*Several bugs have been corrected.

An introduction to this package is available as a vignette (both in
English and in Spanish). Moreover, a handbook of photovoltaic systems  
(in Spanish) is available at
http://procomun.wordpress.com/documentos/libroesf/.

Best regards.
