Hello R users,
I'm wondering whether it is possible to manage big data set in R? I
have a data set with 3 million rows and 3 columns (X,Y,Z), where X is
the group id. For each X, I need to run 2 regression on the submatrix.
I used the function split:
datamatrix-read.csv(datas.csv, header=F,

Hello,
I'm using the R package called mvpart, which is about the multivariate
regression trees.
The function I wrote is:
mrt1- mvpart(coefmat~sChip+sScreen+sMem,data=mixdata, xv=pick,

Still about the mvpart.
Is there any way I can control for the number of elements in each node
in the function mvpart? Specifically, how can I ask partition to
ignore node with elements less than 10?
Thanks!
