This is a fairly simply question. But I couldn't find the answer per google/stackexchange and looking at the documentation of magrittr. How do you feed the result of a chain of functions which are connected via %>% to create a vector?

what I saw most people do is:

a <-
data.frame( x = c(1:3), y = (4:6)) %>%
sum()

but is there also a solution where I can just pipe-chain the result to feed it to an object, maybe an alias or sth of the like, somewhat like this:

data.frame( x = c(1:3), y = (4:6)) %>%
sum() %>%
a <- ()

this would help with keeping all of the code in the same logic of feeding results forward "down the pipe".

Try this:

data.frame( x = c(1:3), y = (4:6)) %>% sum -> a
