A question about R environment
Hi all,
I created environment "mytoolbox" by : mytoolbox <- new.env(parent=baseenv())
Is there anyway I put it in the search path ?
If you need some background :
In a project, I often write some small functions, and load them into my workspace directly, so when I list the objects
with ls(), it looks pretty messy. So I am wondering if it is possible to creat an

A question about dput
Hi,
I am trying to output a R data set for use in WinBugs, I used
dput(list(x=rnorm(100),N=100),file="bug.dat")
But I can't get the intended format: list(x=c(.......),N=100), instead, I got
something like this (copied the first two lines):

How to debug reference classes?
How do you debug methods of a reference class? I've been using mtrace, which
is excellent, but i cannot figure out how to mtrace a reference class
method. Maybe there is some other way to debug these, for example with
ordinary trace? for now i am only able to use options(error=recover), which
is not giving me idea where exactly in the code i am once i am stopped on an
error.

How to import data as numeric array?
Did some search but couldn't find useful result.
I am trying to read a n*m dimension data with read.table, what i need is a numeric array,
is there any efficient way to allow me get this array directly instead of a list?
I tried to use as.array() to change the mode, but seems it doesn't work and i got this error message:

how to debug (mtrace) a function defined inside a function?
Hi, everyone. I am using a fair amount of closures in my code. Problem i am
experiencing is i cannot figure out how to mtrace functions defined within a
function. There must be some way to name such function for mtrace to see it
and let me step into it. For example, say i have code
mymodel<-function(){
data<-numeric(0)
build<-function(){
data<<-1
}
m<-list()

Questions about paste and assign
Hi,
I would like to assign a value to a member b of the list a in position 3, by calling:

but haven't got the right answer yet.

Efficiency of for-loop in R
Hi,
I just realized that in Matlab, as long as memory is pre-allocated, doing for-loop doesn't cost more time than doing things in vector form.
But it seems in R, it still cost a lot to do for-loop. Is there any improvement in R that I missed. Thanks a lot.

[LLVMdev] alloca & store generation
I am writing a transformation that needs to add a call to a function F()
