Dear list members,
I recall seeing a convenience function for applying multiple functions to
one object (i.e., almost the opposite of 'mapply’) somewhere.
Example: If the function was named ’fun’ the output of
fun(3.14, mode, typeof, class)
would be identical to the output of
c(mode(3.14), typeof(3.14), class(3.14))
Is my memory failing me, or does such a function already exists in a
package? Of course, it’s not difficult to define a summary function and
apply this to the object, but writing, for example,
fun(x, mean, median, sd, mad)
to quickly show the relevant information is much more *convient*.
It would be even nicer with a function that could also handle vectors and
lists of values, and output the result as data frames or matrices. Example:
x = c("foo", "bar", "foobar")
fun(x, nchar, function(st) substr(st, 1 ,2) )
y = list(3, 3L, 3.14, factor(3))
fun(x, mode, typeof, class)
