micEcon 0.6-18 (2022-09-03)

clarified a warning message in predict.quadFuncEst()
updated the reference output of a test script due to changes in the "plm" package

added predict() methods for objects returned by quadFuncEst() and translogEst()
moved function translogRayEst() and associated functions to a development version of a new package called micEconDist (not yet available on CRAN)
moved functions for calculating price and quantity indices to a development version of a new package called micEconIndex (not yet available on CRAN)
moved function logDataSet() from package "miscTools" to this package
logDataSet() now also works for (panel) data sets that were created by pdata.frame()

'micEcon' no loger depends on package 'miscTools' but imports this package
no panel data (e.g. cross-sectional data): fixed the returned 'model.matrix' in the presence of categorical explanatory variables
panel data: the returned object no longer includes the 'model.matrix'

separated tools for non-parametric microeconomic analysis into a new package micEconNP (currently only available via micEcon's RForge site)
added data set "appleProdFr86"
quadFuncEst() and translogEst() now return components "r2" and "r2bar" also when a panel data model was estimated by plm()
if the data set is a panel data frame, quadFuncEst(), and hence, also translogEst(), should call plm() rather than lm() again (the class name of panel data frames has changed)

translogCheckMono() now automatically removes the coefficients of shifter variables before it calls translogDeriv() so that it can be used also with models that have shifter variables now

removed argument "quadHalf" of many functions for econometric analysis with the translog and quadratic functional form, because this argument is confusing and not really helpful
translogCheckMono() now can check whether a translog function is monotonically decreasing in some explanatory variables and monotonically increasing in other explanatory variables
the "micEcon" package no longer *depends* on the "systemfit" package but *suggests* it now

The "micEcon" package has been split into three packages again: a) micEconSNQP (version >= 0.6-0): includes all functions and methods for production analysis with the Symmetric Normalized Profit (SNQ) function. b) micEconCES (version >= 0.6-0): includes all functions and methods for economic analysis with the Constant Elasticity of Scale (CES) function. c) micEcon (version >= 0.6-0): includes the remaining parts of the previous version of the micEcon package
function ".micEconLogData" has been moved from the "micEcon" package to the "miscTools" package and was renamed as "logDataSet"

The "micEcon" package has been split into three packages: a) miscTools (version >= 0.6-0): includes miscellaneous small tools and utilities that are not related to (micro)economics, e.g. colMedians(), rowMedians(), insertCol(), insertRow(), vecli(), symMatrix(), triang(), semidefiniteness(), compPlot(), and rSquared(). b) micEconAids (version >= 0.6-0): includes all functions and methods for demand analysis with the Almost Ideal Demand System (AIDS). c) micEcon (version >= 0.6-0): includes the remaining parts of the "old" micEcon package
