A question about logical controls and function arguements
Dear R-help subscribers,
I'm trying to write a function to generate data simulating the image
created by a point radiation source in a plane on a screen where there
is filter with a single circular aperture in it between the source and
the screen.
Following some guides (including Intro to R and some I found online) and
examples I have specified the function (full code below question) with

Passing (Optional) Arguments
Dear List:
In short, I am writing a number of functions as building blocks for
other functions and have some questions about scoping and passing arguments.
Suppose I have functions foo1, foo2, and foo3 such that:
foo1<-function(a=1,b=TRUE,c=FALSE){#do stuff};
foo2<-function(x=1,y=FALSE,z=c(1,2,3,4)){#do stuff};
foo3<-function(lambda,...){lambda*foo1()*foo2()};

Error while using fitdistr() function or goodfit() function
Try changing your method to "ML" and try again. I tried the run the
first example from the documentation and it failed with the same error.
Changing the estimation method to ML worked.
@List: Can anyone else verify the error I got? I literally ran the
following two lines interactively from the example for goodfit:
dummy <- rnbinom(200, size = 1.5, prob = 0.8)

rolling sum (like in Rmetrics package)
Hello, I'm new to R and would like to know how to create a vector of "rolling
sums". (I have seen the Rmetrics package and the rollMean function and I
would like to do the same thing except Sum instead of Mean.) I imagine
someone has done this, I just can't find it anywhere.
Example:
x <- somevector #where x is 'n' entries long

Repeating a series of commands
I'm trying to figure out how to repeat a series of commands in R and have the

batch jobs question
Hi,there
I'm doing some R batch jobs in Unix.
Something like
R <prog1> output1 --save &
R <prog2> output2 --save &
prog1 and prog2 are running at the same time and they are essentially same except it contains different parameter values.
I was wondering if two processes will affect each other? Hopefully they are two independent jobs.
It's a beginner's question

Another loop avoidance question.
Hi
I want to sum over one of the dimensions of a n x k1 x k2 array in
which each column is the product of the corresponding columns from two
matrices with dimensions n x k1 and n x k2. I can see two approaches:
a loop on k1 and a loop on k2. But I cannot figure a solution that
avoids the loop? Is it possible? (I don't refer to apply or lapply etc
either as they are just hidden loops so,

Howto Restart A Function with Try-Error Catch
Hi all,
I have a function - let's call it "myfunction". This function is based
on some random
number generator. Now, once in a while the function will break/crash depending
on the random number it generate inside the function.
To avoid the problem, what I intend to do is the following:
1. Catch the try-error using class.
2. Redo the function if it returns "try-error"
3.

Average over data sets
Hello,
I have a number of files output1.dat, output2.dat, ... , output20.dat,
each of which monitors several variables over a fixed number of
timepoints. From this I want to create a data frame which contains the
mean value between all files, for each timepoint and each variable.
The code below works, but it seems like I should be able to do the
second part without a for loop. I played

Ogg checksum thingie needed
I need some sort of utility to calculate a checksum of an Ogg file.
Two differently encoded Ogg:s should give different checksums, but the
same file with different tags should give the same result.
(The serial number doesn't work here, obviously. I need something that
is changed if a bit of the file is lost.)

data.frame query
Hi All,
Apologies for the simplicity of my question, but I would be grateful for any
advice. Thanks
I'm trying to put the output from a for loop into a data frame, however I
have not been successful.
The steps I have taken are:
*R-code:*
>for (k in 1:(nt-1-n0) ){
> n<- n0-1+k
> lam=n/nt
> Q=x[n]
> output1<-data.frame(cbind(k,n,lam,Q))
> output1
