R Programming Fundamentals

Activity: Creating Vectors, Lists, Matrices, and Dataframes

1. Create vectors using the following code:

vec1 <- c(1:10)vec2 <- c(LETTERS)vec3 <- c(1, "A", 2, "B", 3, "C", 4, "D")

2. Create lists using the following code:

list1 <- list(1:10)list2 <- list(LETTERS)list3 <- list(list("popcorn", "kale"), list("the Blacklist", "This is Us", "The X-Files"), list("run", "listen to podcasts", "paint my nails", "learn data science"))

4. Create matrices ...
