Hi all;
I'm trying to model a response variable (Y) from one (and eventually more...)
independant left-censored variable (X*)

X*= c if x c
Does anyone knows a function or package in [R] enabling to model Y

Hi,
I'm running R version 2.8.1 on Windows and I'm having quite a lot of trouble
just to install package RODBC.

The quantmod package has graphics that are specific to securities.
The zoo package has plot.zoo and xyplot.zoo .
