Hi everybody,
I'd like to have a list with two elements, where both elements have the same
value:
z<- list(a=1, b=1)
If it happens, that I've to change the value, I've to assure that I change
both. This is error prone. H
Hi everybody,
I'd like to have a list with two elements, where both elements have the same
value:
z <- list(a=1, b=1)
If it happens, that I've to change the value, I've to assure that I change
both. This is error prone. Hence, a better way to achieve this is to define:
tmp <- 1
z <- list(a=tm
