'Get.Vars' takes input from the 'v.names' function, and returns
a dataframe consisting of some or all of the named variables.
Arguments:
'vn.out' = the output of 'v.names'.
'v.type' has one of the values, 'data', 'dv', 'factor' or
'quant' depending on whether the output should be all of
the variables, or the dependent variable (dv), or the factor
variables, or the quantitative variables that are named in
the output of 'v.names'.

HDIofMCMC is one of John Krushke's functions for his 2011 textbook
on Bayesian Data Analysis.  The function was downloaded from

'import.spss reads an SPSS file, converts the output from a list to a data frame,
and changes the variable names to lower case.
Arguments:
'file' = SPSS data file to be transformed to an R data file.
'use.value.labels = TRUE' (default) if SPSS variables with value labels are automatically converted
to R factors; if 'use.value.labels == FALSE', the variables are loaded with their numeric values.
'factor.vars = NA' (default) if the default conversions of SPSS variables to R factors is acceptable;
If 'is.na(factor.vars) == FALSE', 'factor.vars' must be a boolean vector of length equal to the number
of SPSS variables.  'factor.vars' lets the user specify exactly which SPSS variables are to be
converted to R factors.  if 'factor.vars' is not NA, then it's settings override the settings
of 'use.value.labels' and 'string.to.factor'.
'lower.names == TRUE' (default) if R variable names are converted to lower case; FALSE if not.
'string.to.factor == FALSE' (default) if SPSS string variables are to be
converted to character variables; 'string.to.factor = TRUE' if SPSS
string variables are to be converted to factor variables.

inv.fun computes the "inverse function" of a two column matrix that represents values of a function.  This function uses old R code -it needs work.
