r - Give name to list variable

Question

so we know that R have list() variable, and also know that R has function call names() to give names for variable. For example :

a=30
names(a)="number"
a
# number
# 30

But now, I want to give a list variable a name, like this :

b=list()
names(b)="number"

and it returns error message like this :

Error in names(b) = "number" : 
'names' attribute [1] must be the same length as the vector [0]

What I have suppose to do? I do this because I need many list variables. Or, do you have another way so I can make many list variables without playing with its name?

Answer 1

Since @akrun doesn't need any more points, here is an example showing how you can assign names to a list:

lst <- list(a="one", b="two", c=c(1:3))
names(lst)
[1] "a" "b" "c"
names(lst) <- c("x", "y", "z")

> lst
$x
[1] "one"

$y
[1] "two"

$z
[1] 1 2 3
