[R] [R-pkgs] Lahman package v. 5.0.0 released to CRAN

[Michael Friendly]

## Lahman package v. 5.0.0 released to CRAN

Team Lahman is pleased to announce that v. 5.0.0 of the Lahamn package 
is now
on CRAN.  It contains the data from Sean Lahman's Baseball Database,
http://www.seanlahman.com/baseball-archive/statistics/
as a collection of data frames covering nearly all aspects of baseball
statistics from 1871--2015.

In this release,

* All data sets have been updated with data for the 2015 baseball 
season.  In
   addition, numerous corrections of data errors and inconsistencies 
discovered
   in previous year tables were applied.

* Documentation examples are now provided for all data tables.

*  Documentation examples were re-writtten to make extensive use of 
dplyr for data manipulation
   and ggplot2 for graphics.

### Development

All development of the package takes place on Github, 
https://github.com/cdalzell/Lahman.
Major versions of the R package are released only once a year, following 
the release of a
new 20XX archive on Sean Lahman's site.  This R release occurs after 
sufficient time has
elapsed to correct errors in the source data for a new season. Minor 
versions may be
released from time to time to correct errors in the R version or add 
functionality.

Please report any problems or issues with this new version as an issue 
on this site,
https://github.com/cdalzell/Lahman/issues.  Additional contributions are 
welcome.

There exists an old pseudo-wiki on R-Forge, 
http://lahman.r-forge.r-project.org/ that
collects some additional analyses and visualizations.
