The "micEcon" package has been split into three packages: miscTools,
micEconAids, and micEcon.

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(). The
miscTools package should depend on (almost) no other packages so that
it can be used in other packages without increasing the total
(recursive!) dependencies of these packages too much.

b) micEconAids (version 0.6-0) includes all functions and methods for
demand analysis with the Almost Ideal Demand System (AIDS) of Deaton
and Muellbauer (1980). Since these functions and methods comprised a
large and rather specific "group" within the "old" micEcon package, it
makes sense (IMHO) to separate them into a separate package.

c) micEcon (version 0.6-0) includes the remaining parts of the "old"
micEcon package, e.g. for economic analysis with Cobb-Douglas
functions, translog functions, quadratic functions, CES (constant
elasticity of substitution) functions, SNQ (symmetric normalized
quadratic = generalized McFadden) profit functions, or linearly
homogeneous non-parametric functions.

I have uploaded all three packages to CRAN. They should be available
for download on CRAN and its mirrors (at latest) in a few days.

Feedback is highly welcome!
