jmbugs.cur is the vector of names of JM's current utility functions for working with BUGS objects.  See 'e:/r/fns/update.jmbugs.docm' for documentation.  Updated 2013-04-27 .  The current functions named by jmbugs.cur are: 

 brugs.chains, ci.bugs, doc, extract.chains, extract.vars, from.mcmc.list, gamma.parameters, make.names.jm, o.type, plot.chains, res.param, show.bugs, to.mcmc.list

jmfiles has been superceded by the update.all function. 
Use update.all instead.

Most recent update of jmfuns.rda:  2014-02-18
jmfuns.rda contains functions written by John Miyamoto for his personal use, 
and the use of his students. As of 4/26/2013, jmfuns.rda underwent a major
revision - many obsolete functions were removed from jmfuns.rda.  These
older functions can be found as code in \r\fns, and they were archived
as R objects in \r\save\jmfuns.130426.rda.

kruschke.files is simply a string that represents the path to the directory where the .r files for Kruschke's textbook are stored on John Miyamoto's computer.  

kruschke.files = "e:/btut/r"

kt.cumwt appears to compute the cumulative weighting function for the Kahneman/Tversky weighting function.  This function is old.  It needs to be checked, possibly revised. 4/27/2013

kt.dwt appears to compute decision weights for a gamble according to the Kahneman/Tversky weighting function.  It allows for different weighting functions for gains and losses. This function is old.  It needs to be checked.  It probably needs revisions.  4/27/2013

'ktwt'  computes the transformed cumulative probability
according to the Kahneman & Tversky (1992) functional.
'kt.dwt' computes the decision weights for a vector of probabilities,
ordered from the probability of the worst to the probability
of the best outcome.
ARGUMENTS (for 'ktwt'):
'p' is a vector of cumulative probabilities.  Note that each
element of 'p' is transformed without regard to other elements
of 'p', i.e., the probabilities are not summed over the
preceding elements.
'gamma' is the parameter of the Kahneman/Tversky functional.
The default value (.65) is typical
