In R what is the equivalent of @ function handle in Matlab?

Question

In Matlab if I have a function f such as the signature is f(a,b,c), I can make a function which has only one variable b, which would call f with a fixed a=a1 and c=c1:

Answer 1

g <- function(b) f(a1, b, c1)

Answer 2

There is also the convenient functional::Curry functional:

f <- function(a, b, c) {a + b + c}
f(1, 2, 3)
# [1] 6

library(functional)
g <- Curry(f, a = a1, c = c1)
g(b=2)
# [1] 6
g(2)
# [1] 6

I think an important difference with @NPE's solution is that the definition of g using Curry does not mention b. So you might prefer this approach when the number of arguments in f becomes large.
