Hi,
I run in the same problem, as discussed in 2006. Is there any solution
by now?

I am having difficulty understanding the envir argument of do.call.
The help page says
envir an environment within which to evaluate the call.
so I thought that in the following toy example x would be found in the
environment e and f would return 4 via do.call:
e - new.env()
e$x - 2

So the trick is to put the function f into e and define its environment to be e:
e - new.env()
e$f - function() x^2
environment(e$f) - e
e$x - 2
do.call(f, list(), envir = e)
[1] 4
Thanks, Duncan.

Putting f into e, and defining the environment of f to be e solve
different problems. Your toy example has both problems so it's a
reasonable solution there, but most
My problem is to evaluate a function/model whose definition and
parameters (I'll put x into the arguments) and other data are saved by
someone else in an Rdata file, but I don't know the function name,
definition or data. Nevertheless, I need to save whatever functional
values/model solutions are

Hi,
thanks for your answer, but in this way R delete all rows with NA. In

I hope you can give me an idea.

Dear R users,
I'd like to compute X like below.
X_{i,t} = 0.1*t + 2*X_{i,t-1} + W_{i,t}
where W_{i,t} are from Uniform(0,2) and X_{i,0} = 1+5*W_{i,0}
Of course, I can do this with for statement, but I don't think it's good
idea because i and t are too big.
So, my question is that

Hi: Use arima.sim because when you have recursive relationships like that,
there's no way to
not loop. If arima.sim doesn't allow for the trend piece (0.1*t ), then you
can do that part seperately using cumsum(0.1*(1:t)) and then add it back in
to what arima.sim gives you. I don't remember if
Hi Kathryn: I'm sorry because I didn't read your question carefully enough.
arima.sim won't help because you don't have a normal error term. I think
you have to loop unless someone else knows of a way that I'm not aware of.
good luck.

Hi R users,
i use do.call() to run some functions on large datasets. For debugging
purposes I occasionally use browser. In the case of large datasets
supplied to do.call, this however results in R printing huge amounts of

because myFun has an environment, and that the global environment. Look at:

Hi all! I need to do something really simple using do.call.
If I want to call the mean function inside do.call, how do I apply the

So, I use do.call(mean, list(x)) where x is my data. This works fine if
there are no NAs.
Thanks,

?do.call
Second argument is a list of arguments to pass. Try do.call(mean,

I'm trying to write a simple wrapper for plotting functions to make

The help pages (here for bquote) are your friend.
I don't think you really want to do this via do.call(), as you want some
arguments evaluated and some unevaluated. Rather, match.call(), alter it
as you want, and then eval.parent it. Something like
