Dear R-helpers,
Suppose I have a dataset,
data(iris)
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))
b - iris[1:10,]
newtest.iris - rbind(a,b)
newtest.iris
Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1
Try:
a - data.frame(Sepal.Length=1:4, Sepal.Width=2:5,
Petal.Length=3:6, Petal.Width=4:7,
Species=rep(rosa,4))
b - iris[1:10,]
newtest.iris - rbind(a,b)
names(newtest.iris) - c(SL, SW, PL, PW, Class)
newtest.iris$Class - as.numeric(newtest.iris$Class) - 1
HTH,
Excellent, this is exactly what I was looking for.
Many thanks and best regards,
Muhammad Subianto
