In body(fun, envir = environment(fun)) <- value, value can be an
expression or a list of R expressions.
But it seems that value must be length-1 list (if it is a list), is it right?
> f2 <- function(x) {}
> body(f2) <- list(quote(x<- x^5),quote(return(y)))
Error in as.function.default(c(formals(fun), value), envir) :
invalid formal argument list for "function"
I want to construct a function by computing, what I do at this moment
is as follows:
>f <- function(x) {}
> body(f)[[2]] <- quote(x<- x^5)
> body(f)[[3]] <- quote(return(y))
Is there a better way to do this?
Thanks
