I am having trouble figuring out how to use do.call to call and run a list
of
functions.

for example:

make.draw = function(i){i;function()runif(i)}
function.list = list()
for (i in 1:3) function.list[[i]] = make.draw(i)

will result in

function.list[[1]]()

?[1] 0.2996515

function.list[[2]]()

?[1] 0.7276203 0.4704813

function.list[[3]]()

?[1] 0.9092999 0.7307774 0.4647443

what I want to do is create a function that calls all three functions in
the
list at one go. from what I understand as.call() can be used to do this but
I am having trouble connecting the dots and getting 6 uniform random draws
from function.list. thanks, honeyoak.

Thanks for the reference, the each function in the plyr package is  
exactly
what I wanted.
