Is there something like a function composition in R?
I think in haskell it\'s somthing like \"(.)\" and in agda it\'s the ring operator.
Also, I find litte infor
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...).
