Exercise

Creating a named list

Well done, you're on a roll!

Just like on your to$-$do list, you want to avoid not knowing or remembering what the components of your list stand for. That is why you should give names to them:

This creates a list with components that are named name$1,$ name$2,$ and so on$.$ If you want to name your lists after you've created them, you can use the names$()$ function as you did with vectors. The following commands are fully equivalent to the assignment above:

$m{y}_L$ist List$(you{r}_c$omp$1,you{r}_c$omp$2)$

names $(n{y}_l$ist name$2)$

Instructions

$100P$

Change the code of the previous exercise $($see editor$)$ by adding names to the components. Use for my$\_$vector the name vec, for my$\_$matrix the name mat and for imy$\_$df the name df $.$

Print out my$\_$list so you can inspect the output.

script:R

F Vector with numerics from $1$ up to $10$ my$\_$vector :$10$

# Matrix with numerics from $1$ up to $9$

my$\_$matrix matrix $,$ ncol $=3$

# First $10$ elements of the built$-$in data frame mtcars my$\_$df mtcars $,$

# Adapt list$()$ call to give the components names my$\_$list list$($my$\_$vector, my$\_$matrix, my$\_$df$)$

# Print out my$\_$list
