Hello, Is there a simple way of stacking/merging two dataframes in R? I want to stack them piece-wise, not simply add one whole dataframe to the bottom of the other. I want to create as follows: x.frame: aX1 bX1 cX1 ... zX1 aX2 bX2 cX2 ... zX2 ... ... ... ... ... aX99 bX99 cX99 ... zX99 y.frame: aY1 bY1 cY1 ... zY1 aY2 bY2 cY2 ... zY2 ... ... ... ... ... aY99 bY99 cY99 ... zY99 new.frame: aX1 bX1 cX1 ... zX1 aY1 bY1 cY1 ... zY1 aX2 bX2 cX2 ... zX2 aY2 bY2 cY2 ... tY2 ... ... ... ... ... aX99 bX9...

I am trying to generate a set of random numbers that fulfill the following constraints: X1 + X2 + X3 + X4 = 1 aX1 + bX2 + cX3 + dX4 = n where a, b, c, d, and n are known. Any function to do this? Thanks, -Ala' [[alternative HTML version deleted]]

Hi, I have experimental response (Y) and many (important or not) actions (X). I want to create model: Y = aX1 + bX2 + ... + eX5 (1) from few most important actions of course. As I understand I have to use plsr for this task. I learned read.table and plsr R functions and how to plot some results from them, but still do not understand how I can get (or construct) function I need (function 1)? [[alternative...
