Getting ready

Recall that you have created several R objects in the prior recipes, such as vector, matrix, data frame, and array. Now, you are in a position to create another single R object that could contain all the objects that you have already created and then want to access those as needed. To get ready for this recipe, let's re-run those lines of code and create those objects again:

    cVec <- c("Cricket", "Football", "Basketball", "Rugby")
    nVec <- c(1:10)
    Lvec <- c(TRUE, FALSE, FALSE, TRUE)
    matA <- matrix(1, nrow=2, ncol=2)
    datA <- data.frame(ID = 1:5, hourSpetOnInternet = c(5,3,4,1,2),  
    GENDER = c("M", "F", "F", "M", "F"))
    arrayA <- array(1:16, dim=c(2,2,4))

In this recipe, you will organize these heterogeneous objects into a single R object that is called list.
