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)

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

x1 x2
1 1 1

could some tell me how it is possible to do this?

Thank you!
