Dear R-help,
First I apologize if my question is quite simple.
I need add some of data in the first place my dataset, how can I do that.
I have tried with rbind, but I did not succes.
0.1 3.6 0.4 0.9 rose
4.1 4.0 1.2 1.2 rose
4.4
Try this:
x- matrix(1:12, nrow = 4, byrow = T)
y - matrix (13:24, nrow=4, by.row=T)
To add the rows of y before the rows of x:
rbind(y,x)

Can you send a reproducible example where rbind
If you want to add rows to a data frame using rbind, your additional rows must
be in a data frame with the same (column) names.
R data( iris )
R a - data.frame( Sepal.Length=c(1:4), Sepal.Width=c(2:5),
Petal.Length=c(3:6), Petal.Width=c(4:7), Species=rep(rosa,4))
R b - iris[1:10,]
