Hi All,
I've just recently discovered the cmpfun function, and was wanting to to
create a function to assign this to all the functions i have created, but
without explicitly naming them.
I've achieved this with:
foo<- function(x) { print(x)}
bar<- function(x) { print(x + 1)}
foo<- function(x) { print(x)}
foo
function(x) { print(x)}
cmpfun(foo)
function(x) { print(x)}
<bytecode: 0x26e3d40>
find.all.functions<- ls.str(mode = 'function')
for(i in seq_along(find.all.functions)) {
assign(find.all.functions[i], cmpfun(get(find.all.functions[i])))
}
But remember told that using assign is generally a bad idea, and ideally i
want to functionalize this to say something like:
CreateCompiledFunctions<- function() {
find.all.functions<- ls.str(mode = 'function')
for(i in seq_along(find.all.functions)) {
assign(find.all.functions[i], cmpfun(get(find.all.functions[i])))
}
}
Does anyone have a better solution?
Put your functions in a package, and install it with the --byte-compile
option. This is better in two ways:
1. You have a package, which is *much* better than having a bunch of
functions sitting around in an .Rdata file.
2. You don't recompile functions that are already compiled.
