r - How to nest multiple pipes magrittr -

this starts aestethic question turns functional one, magrittr.

i want add data_frame manually input 1 there so:

cars_0 <- mtcars %>%    mutate(brand = row.names(.)) %>%   select(brand, mpg, cyl)   new_cars <- matrix(ncol = 3, byrow = t, c(   "vw beetle",   25, 4,    "peugeot 406", 42, 6))   # coercing types not issue here.  cars_1 <- rbind(cars_0,    set_colnames(new_cars, names(cars_0)))  

i'm writing new cars in matrix "increased legibility", , therefore need set column names bound cars_0.

if likes magrittr as do, might want present new_cars first , pipe set_colnames

cars_1 <- rbind(cars_0, new_cars %>%    set_colnames(names(cars_0)))      

or avoid repetition they'll want indicate cars_0 , pipe rbind

cars_1 <- cars_0 %>%    rbind(., set_colnames(new_cars, names(.))) 

however 1 cannot both there confusion whom being piped

cars_1 <- cars_0 %>%    rbind(., new_cars %>% set_colnames(names(.))) ## error in match.names(clabs, names(xi)) :  ##   names not match previous names 

my question: there way distinguish 2 arguments piped?

short answer: no.

longer answer: i'm not sure rationale doing be. philosophy behind magrittr unnest composite functions, primary intent of making easier read code. example:

f(g(h(x)))  

becomes

h(x) %>% g() %>% f() 

trying use pipes in manner places 2 objects interpreted . argument goes against philosophy of simplification. there circumstances in can have nested pipes, environments ought remain distinct. trying cross 2 pipes in same environment can likened crossing streams.

don't cross streams :)
