Finding all functions in current workspace

I'd like to find all functions in my current workspace and thought about using is.function for that purpose.

The "problem" is that is.function expects a true R object, not the character string name of an object.

That's my solution, but using eval(substitute(...)) seems a bit involved. Any ideas for a more straight forward way or is that the only way this can be done?

Example content

x <- TRUE
y <- 10
foo1 <- function() message("hello world!")
foo2 <- function() message("hello world again!")

Finding all function objects

wscontent <- ls(all.names=TRUE)
funs <- sapply(wscontent, function(ii) {
    eval(substitute(is.function(OBJ), list(OBJ=as.name(ii))))
})
> funs
     foo1      foo2      funs wscontent         x         y 
     TRUE      TRUE     FALSE     FALSE     FALSE     FALSE
Solution

  • How about

    lsf.str()

    which should list all functions.
