Test on mu with multivariate normal distribution
...thought ?simtest? could be the right function to get the p-value, but I fail to use R correctly. Here is what I tried to do:
f1 <- factor(c("8", "10", "12", "14"))
X <- matrix(1:16, ncol=4)
colnames(X) <- c("Obj1","Obj2","Obj3","Obj4")
X.frame <- data.frame(f1,X)
Y <- matrix(1:12, ncol=4)
colnames(Y) <- c("Obj1","Obj2","Obj3","Obj4")
Y.frame <- data.frame(f1,Y)
XY <- data.frame(X.frame, Y.frame) # won?t work, because of different nr of rows

Linking different Models together and walking them dynamically?
...nough unique
properties to warrant their own tables.
I was thinking of creating a column called ''type'' and having that be
the name of the Model/Class, and make Ruby call that class, but I
don''t know if Ruby can inject a variable and use it as a name
So, obj1 connects to obj3 connects to obj2
obj2 is of Model ''x'',
obj1 is of Model ''y'',
obj3 is of Model ''z''.
And the columns would be: src | dest | src_type | dest_type
Where src_type (and dest_type) is the name of a Model
Any ideas on how to do this? Any speculation...

reporting multiple objects out of a function
Dear folks,
I?m trying to build a function to create and make available some variables I
frequently use for testing purposes. Suppose I have a function that takes
some inputs and creates (internally) several named objects. Say,
fun1 <- function(x, y, z) {obj1 <- x; obj2 <- y; obj3 <- z
<missing stuff>
}
Here is the challenge: After I run it, I want the objects to be available in
the calling environment, but not necessarily in the global environment. I
want them to be individually available, not as part of a list or some larger
object. I can not figure out how to...

Looping through R objects with $ operator and tags
Hi all,
Suppose I want to set the values in a column to the log of the values
of another column like so:
object$LogDist <- log10(object$Distance)
How do I loop through the objects if I have object1, object2, etc to
perform this function?
object1$LogDist <- log10(object1$Distance)
object2$LogDist <- log10(object2$Distance)
object3$LogDist <- log10(object3$Distance)
I was trying to

How difficult is it to wrap a large C++ library with R?
...sing R? If most
of the answers are yes, it may be a good idea to switch to R.
* Wrap C++ class hierarchy. Virtual functions need to be supported.
(SWIG can generate Python shadow classes that behave almost exactly
like the underlying C++ classes)
* Be able to do this:
evolve(ops=c(obj1, obj2, obj3))
Internally, evolve will call virtual function fun() of obj1, obj2, .etc.
obj1, obj2, ... are objects derived from the same base class.
* Direct access to C++ data structure. For example, an object may keep
a C array internally. I will need a method (maybe wrap this data into
a R object) to...

attach and detach question
I have a large R program that I am constantly running over and over again. At the beginning of this program, I create a hige matrix and a huge dataframe but these are constant. What I mean by constant is that, if I run the program over later, I really should just use the old matrix and dataframe ( if they exist ) that were created in a previous run so that the program doesn't have to spend

x axe values
Dear list,
I have to draw a simple plot. On y axe some numerical values that correspond
to various categories on axe x.
The table I am reading looks like:
cat Obj1 Obj2 Obj3
max 23 27 34
ave 21 25 32
min 19 23 30
In order to avoid that the first column is reordered alphabetically I used:
(found here http://tolstoy.newcastle.edu.au/R/help/06/09/33808.html)
a <- as.character(table$cat)
table$cat = factor(a, levels=a)
However if I use plot() I get thick lines instea...
