Dear all,
I have a function MYFUN which depends on 3 positive parameters TETA[1],
TETA[2], and TETA[3]; x belongs to [0,1].
I integrate the function over [0,0.1], [0.1,0.2] and
[0.2,0.3] and want to choose the three parameters so that
these three integrals are as close to, resp., 2300, 4600 and

R has amazing capabilities, but percentage tables are a weak spot
IMHO. There's prop.table but that's rather unwieldly, especially for
multiway tables. CrossTable by Marc Schwartz in the gregmisc library
makes percentage tables a breeze but is limited to two-way tables. So

I am using the rpart() function to perform a recursive tree analysis on a
set
of data that includes both numerical and categorical attributes.
At the end of the analysis, I would like to see the linear model at each
node in the tree. In particular, I would like to see each
Rpart does not fit a linear model at any node. Please read up on
tree-based models.
