R - for loop only gives the last interaction result

I am trying to save the results of all interactions, but for loop only gives me the result of last interaction. Just like this:

l <- list(a = c(1, 3, 5), b = c(4, 8), c = 2)

df <- data.frame()

for (i in 1:length(l)) {
  
  s <- data.frame(name = names(l[i]),
                  value = mean(l[[i]]))
  
  out <- rbind(df, s)
}

This code returns this:

I need to something like this:

How can I solve this?

Thanks in advance!

Your out variable only contains the result of the last iteration since out is overriden in every iteration of the loop.

Replace out by df like so, your expected result will be in the df variable:

l <- list(a = c(1, 3, 5), b = c(4, 8), c = 2)
df <- data.frame()

for (i in 1:length(l)) {
  s <- data.frame(name = names(l[i]),
                  value = mean(l[[i]]))
  df <- rbind(df, s)
}
df
