Version 1.0-0

o Rewrote summary.effect method and added print.summary.effect method.

Version 1.0-1

o Blanks can be inserted into or removed from effect names without causing an error; thus, e.g., "poly(education,3)" is equivalent to "poly(education, 3)".

o Name spaces of lattice and grid packages are imported, as required in R 1.8.0.

Version 1.0-2

o Added ask argument to plot.effect.list, and row, col, nrow, ncol, and more arguments to plot.effect, to support graphing an array of effect plots.

o Fixed bug in plot.effect that caused xlab argument to be ignored in certain circumstances.

Version 1.0-3

o effect function now works if na.action is na.exclude.

Version 1.0-4

o Fixed small bug introduced in version 1.0-3.

Version 1.0-5

o x.var and z.var arguments to plot.effect now take names as well as indices.

Version 1.0-6

Version 1.0-8

o Small fixes to the help files.

Version 1.0-9

o Small change to compile without a warning in R 2.4.0.

Version 1.0-10

o Standard errors of effects are computed using t rather than standard-normal distribution for models with estimated dispersion (as suggested by Brian Ripley).

o Small fixes.

o Objects are now named "eff" and "eff.list" rather than "effect" and "effect.list".

o Data sets now provided by lazy data.
