Is it possible to combine the forward pipe operator with an anonymous function? If so then how can i go about it?
I get that the basic idea is to pass arguments in a sequential manner for the functions to execute.Like below,first the anonymous function calculates the sum then passes it on to the factorial function.
How can I do the same
This is what I am trying to execute using the forward-pipe operator-
calculate <- function(func,d)
{
func(d)
}
factorial(calculate(function(x){x+1},7)) # function x is the anonymous function
My code using the forward-pipe operator-
7 %>% calculate(function(x){x+1}) %>% fact()
the expected result is 40320, but it results in
Error in func(d) : could not find function "func"
Another option is to call calculate
's arguments explicitly using name
7 %>% calculate(func=function(x){x+1}) %>% factorial()
