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.
Can you send a reproducible example where rbind didn't succeed?
0.1 3.6 0.4 0.9 rose
4.1 4.0 1.2 1.2 rose
4.4 3.2 1.9 0.5 rose
4.6 1.1 1.1 0.2 rose
For example,
> data(iris)
> iris[1:10,]
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1 5.1 3.5 1.4 0.2 setosa
2 4.9 3.0 1.4 0.2 setosa
3 4.7 3.2 1.3 0.2 setosa
4 4.6 3.1 1.5 0.2 setosa
5 5.0 3.6 1.4 0.2 setosa
6 5.4 3.9 1.7 0.4 setosa
7 4.6 3.4 1.4 0.3 setosa
8 5.0 3.4 1.5 0.2 setosa
9 4.4 2.9 1.4 0.2 setosa
10 4.9 3.1 1.5 0.1 setosa
Assume that you have the new data in a `data.frame', e.g.
> (new.data <- read.table("clipboard", header = FALSE, col.names = c("Sepal.Length", "Sepal.Width", "Petal.Length", "Petal.Width", "Species")))
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1 0.1 3.6 0.4 0.9 rose
2 4.1 4.0 1.2 1.2 rose
3 4.4 3.2 1.9 0.5 rose
4 4.6 1.1 1.1 0.2 rose
Then,
add.data <- rbind(new.data, iris)
will do the trick. Confirm this by
> add.data[1:10, ]
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1 0.1 3.6 0.4 0.9 rose
2 4.1 4.0 1.2 1.2 rose
3 4.4 3.2 1.9 0.5 rose
4 4.6 1.1 1.1 0.2 rose
151 5.1 3.5 1.4 0.2 setosa
210 4.9 3.0 1.4 0.2 setosa
310 4.7 3.2 1.3 0.2 setosa
410 4.6 3.1 1.5 0.2 setosa
5 5.0 3.6 1.4 0.2 setosa
6 5.4 3.9 1.7 0.4 setosaHTH, Henric
