Subset dataframe using a loop

Question

I have a data frame that looks like this:

index   ID   date              Amount
2       1001 2010-06-08         0
21      1001 2010-10-08        10
6       10         


        

Answer 1

    iris_split <- split(iris, iris$Species)

Dynamically you can assign the data.frame name

    new_names <- as.character(unique(iris$Species))

    for (i in 1:length(iris_split)) {
    assign(new_names[i], iris_split[[i]])
    }
