[R] matrix manipulations

[Anup Nandialath]

Dear friends,

I have a basic question with R. I'm generating a set
of random variables and then combining them using the
cbind statement. The code for that is given below.

for (i in 1:100)
  {
    y <- rpois(i,lambda=10)
    X0 <- seq(1,1,length=i)
    X1 <- rnorm(i,mean=5,sd=10)
    X2 <- rnorm(i,mean=17,sd=12)
    X3 <- rnorm(i,mean=3, sd=24)
    ind <- rep(1:5,20)
  }
  
data100 <- cbind(y,X0,X1,X2,X3,ind)

but when i look at the data100 table, the y values now
take the observation count. (ie) the data under Y is
not the poisson random generates but the observation
number. Hence the last vector (ind) does not have a
header. Is there any way i can drop the number of
observation counts being added into the matrix.

Thanks in advance for your help.

Sincerely

Anup
