Search notes:
R function: ls
ls shows the variables and functions that are defined in a
workspace (or environment(?)).
Variables whose names start with a dot are not returned by default. Setting all.names to TRUE changes this behavior.

var_1 <- 42
var_2 <- sqrt(var_1)
var_3 <- var_2 * var_2
.hidden <- "Not shown by ls"

ls(all.names = TRUE)
