    You may make compositing function like this:

    composite<-function(f,g) function(...) f(g(...))
    
    f<-function(x) x+1;
    g<-function(x) x*2;
    composite(f,g)(7)
    composite(g,f)(7)
    

    or make operator of this.

    About the second point, there are lots of such; I think the most used are the *apply family (sapply, mapply, tapply, lapply, apply...).
