Try this:

m <- seq(-1,1,0.1)
  x1 <- vector(length=length(m))
  x2 <- vector(length=length(m))
  for(i in m){
  x1[i] <- i
  x2[i] <- i^2
  }
  dat <- data.frame(x1,x2)

Ravi.

Hello all,    

  I am trying to use    

  m <- seq(-1,1,0.1)
  x1 <- vector()
  x2 <- vector()
  for(i in m){
  x1[i] <- i
  x2[i] <- i^2
  }
  dat <- data.frame(x1,x2)
  But, I have false result
>dat
