How to convert List object to function arguments?

For instance:
##### BEGIN CODE SNIP #####
parms <- list( shape1 = 2, shape2 = 5 );
goftests( x, "beta", parms[["shape1"]], parms[["shape2"]] ); # Works!
goftests( x, "beta", parms ) # Don't Works!
parms <- list( aNum = 5, aVector = c(1,2,3), aMatrix =

distance coefficient for amatrix with ngative valus
Hi,
I need to run a PCoA (PCO) for a data set wich has both positive and negative values for variables. I could not find any distancecoefficient other than euclidean distace running for the data set. Are there any other coefficient works with negtive values.Also I cannot get summary out put (the eigen values) for PCO as for PCA.
Thanks.

Missing values for S4 slots
Using R 2.4, the following fails:
setClass("testc", representation(a="ANY"))
makeC <- function(myarg) new("testc", a=myarg)
makeC()
-> Error in initialize(value, ...) : argument "myarg" is missing,
with no default
On the other hand, this is OK:
f <- function(a) g(b=a)
g <- function(b) if(missing(b)) "missing" else "valid

using save() to work with objects that exceed memory capacity
Context: I'm relatively new to R and am working with very large datasets.
General problem: If working on a dataset requires that I produce more than
two objects of roughly the size of the dataset, R quickly uses up its
available memory and slows to a virtual halt.
My tentative solution: To save and remove objects as they're created, and
load them when I need them. To do this I'm

vardiag package help
...ompare results
doing other plots as well. I used ?cook.distance? on lm and glm
objects, but still I am not happy with that.
So now I am loading the ?vardiag? package. First thing is to
transform my data (frame.data) into a matrix ? which I did with
?as.matrix?. I verify my new object as being amatrix ? and it is,
and I list it to be sure that in is a matrix of n rows with 3 colums.
Now I want to use the command ?varobj? to transform my
matrix into a variogram object.
The param are:
varobj(m, iter = 50, tolerance = 2e-04, trace = 1, loo = F)
where, m is a n by 3 matrix with spatial data.

retaining formatting when converting a vector to a matrix/data.frame?
Please see example code below.
I have a vector ("mydata") of length 10. "mydata" can have various formats (e.g. numeric, text, POSIXct, etc) I use the matrix and data.frame functions to convert "mydata" to a dataframe ("mydf") of 2 columns and 5 rows.
What is a "good" way to ensure that the format is retained when I create the
