Dear R users,
I've just uploaded to CRAN a new version of RTisean, the TISEAN-to-R interface.
This is now compatible with the recent, new 3.0.1 release of TISEAN [1].
This new TISEAN version is explicitely GPL-ed, and has some more
routines handling multivariate time series.
Bests,
Antonio, Fabio

Thanks for the tip. I had thought of using the demo facility for this
but I didn't know how to check for the operating system.
See help about '.Platform'. I.e.,
.Platform$OS.type
can be useful.
This is a clumsy solution, but better than nothing. I
put the constrained predictor in the model offset ('offset' argument in 'lm').
i.e.:
set.seed(10)
X - matrix(rnorm(20), 10, 2)
y - X %*% c(1,2) + rnorm(10)
coef(lm(y ~ X[,2], offset=X[,1]))
(Intercept) X[, 2]
-0.8009112 1.6968198
coef(lm(I(y-X[,1]) ~ X[,2]))

internal functions by putting a leading '.'.
Even without namespace, I have noticed there is no check for corresponding
