I want to "melt" my list and get certain deskriptive factors (length of a vector etc.) into a dataframe. Best to describe it with an example:

A <- seq(4)
B <- seq(6)
C <- seq(9)

ls <- list(A,B,C) # this is my list with vectors of different length

# thats the dataframe how it should look like:
name	length(x)	length(x[x>5])	length(x[x<5])	
A	4	0	4
B	6	1	4
C	9	4	4

How can that be achieved?
