Is it possible to use currying in R?
One possibility is to have special paste functions (it can be considered as a follow up to here), e.g. (in incorrect code):
'%+%' <- (sep)function(x,y) paste(x,y,sep=sep)
"a"%+%("")"b"%+%("_")"c" #gives "ab_c"
What would be a possible implementation in R?
PS: The paste is just an example, I am curious about the possibilities of R...
回答1:
It is possible to curry in R, and there is a definition in the ROxygen package. See the discussion here
回答2:
The standard place for functional programming in R is now the functional library, this library substitutes the ROxigen library that is discussed here :
library(functional)
newfunc <- Curry(oldfunc,x=5)
