'sw.bugs' is used to switch the R configuration between R2OpenBUGS, R2WinBUGS, R2jags, BRugs, and rjags.   

program = 'open' switches to an OpenBUGS configuration.
program = 'win' switches to a WinBUGS configuration.
program = 'jags' switches to an JAGS configuration.
program = 'brugs' switches to a BRugs configuration.
program = 'rjags' switches to a rjags configuration.

'sw.bugs' uses partial matching on the 'program' argument.  Thus, 'program = "w"' and 'program = "WinBUGS"' both have the same effect as 'program = "win"'.  And similarly for 'program = "o"' and 'program = "OpenBUGS"' or 'program = "r2j"' and 'program = "R2jags"'.   

If 'sw.bugs' is used to detach R2jags from the search path, most of the packages that were attached by the call to 'library(R2jags)' are detached.  The exceptions are the 'coda' and 'lattice' packages which are attached by a call to 'library(R2jags)' but are often used in combination with OpenBUGS.  Therefore they are left on the path.

'SW.table' makes a model comparison table like those shown
in Singer and Willett (2003).  Use the 'digits' arguments
to control the number of digits to the right of the decimal
place.

'Sys.info.UHouse' shows the output of 'Sys.info()' when it is run on
the University House computer.

'Sys.info.X220' shows the output of 'Sys.info()' when 
the user is logged in as 'John M. Miyamoto' on the X220 laptop.

If output == 'string', Sys.time.jm outputs a string that
states the year-month-day and hour:minute:second of the moment
at which the call was made.
If output == 'vector' (default), Sys.time.jm outputs a
numeric vector whose components are the year, month, day,
hour, minute, second of the moment at which the call was made.

'to.mcmc.list' takes a list that was created by a call to extract.chains
and creates a list of class mcmc.list.  The functions in the coda
package require inputs that are organized as an mcmc.list and have
the mcmc.list class attribute.  Thus, the 'to.mcmc.list' function creates
a list of chains that is suitable for analysis by using functions in
the 'coda' package.
ARGUMENTS:
'bugs.out' = a list that was created by a call to 'extract.chains'.
