Hello,
Once again, the matrix EWMA has not the correct size.
Did you carefully read the answer by Thomas Stewart?

Extract of his reply: When you expand the example to 5 stocks,
there will be 15 elements (5

Hello,
I'm a complete newbie to R so sorry if this is too basic..:-S
I have to modify some scripts someone else did to make it work with my data.
For some reason, one of the scripts which were supposed to work is not, and
I get the error message number of items to replace is not a multiple of
Here is an example to use as a starting point for what that error message
means.
x - 1:6
x[1:5] - 1:2
Warning message:
In x[1:5] - 1:2 :
number of items to replace is not a multiple of replacement length
The expression
x[1:5] -
means that we are about to replace the first five elements
Thanks a lot, I thought I was moving forward because I got a different error,
but it seems that I didn't move forward at all..:-S...It was quite basic,
right...?
That was very helpful, I'll try to sort out the dimensions problem now on my
own...I want to fight a bit with it to see if I'm able to

Hey all,
I am writing a function in which I will have a matrix of 4 columns and a
variable amount of rows.
The first to columns will always contain be of the Character type, the third

sometimes lists or
Hi,
I think you _*should*_ provide more:
- the objects you have, such as parameterList and blaah: copy the output
from dput(object) in your next e-mail
- the _*relevant*_ code for how you've built them
I guess you will get more and better answers if you give a clear and
complete description
Hello,

Hello,
I just wanted to say that I just stumbled upon the solution by accident!
After your comment on lists I searched for some more information on vectors,
lists and matrices. I read that using double ['s instead of singles drops
the names of the dimensions used.
I then gave
Hi,
I am trying to run some bootstraps with the boot package. When I run
it with 400 replicates it does it ok, but then I need to run the same
analysis but with 89, 86, 102 and 106 samples (for four different
environments), and then is when I get the error message:
