# ---------------------------------------------------------------------
# version 0.6.1

Removed German umlauts for proper compiling

# ---------------------------------------------------------------------
# version 0.6

New features

- Added parameter "cubic" to RSA function. If set to TRUE, also a cubic surface is fitted, adding four new parameters to the equation: X^3, Y^3, XY^2, and X^2Y
- Added parameter "project" to plotRSA. If project=TRUE, all lines which are defines by parameter "axes" are projected onto the floor of the cube.
- plotRSA now can plot a convex hull around the data points (set hull=TRUE); both in type="3d" and type="contour"
- plotRSA now can plot the CI of the stationary point (set SP.CI=TRUE); only for type="contour"
- All surface parameters now are also calculated for IA and sqdiff models

Changes:
- Changed parameter name "showBorder" to "border"
- Changed parameter name "showContour" to "contour"


# ---------------------------------------------------------------------
# version 0.5.1

New features

- Added parameter "surface" to plot.RSA. surface = "predict" (default) plots the predicted surface. This is the known behavior of the function. surface = "smooth" plots a 2d-smoothed surface of the raw data (employs the Tps function of the fields package).



# ---------------------------------------------------------------------
#  version 0.4

- first "public" release
- no known bugs


# Known Todos:
- axes labels in plot.RSA(type="3d") have the correct rotation for the default plot rotation, but they do not rotate with the plot.
