First of all, you need to store as a list not a vector if you;re storing the
entire output. Otherwise, you can just store, for example, cor.test(...)$p.value

The short answer on comparing R and Matlab is that it depends on
your benchmark and which church you happen to frequent. Some people
swear that Matlab is superior, but I haven't seen the evidence for
that. The benchmarks that come closer to being transparent are more
equivocal, as far as
Hello,
Is there a way to extract output objects from a stats test without viewing
the entire output? I am trying to do so in the following:
define a vector of length j
for( i in 1: length (vector)) {
vector[i] = cor.test (datavector1, datavector2[i], method=("spearman"))
}
I would like the rep
Dear Gundala,
Try this:
# Data set
DF=read.table(textConnection("300.35 200.25 104.30
22.00 31.12 89.99
444.50 22.10 43.00
22.10 200.55 66.77"),header=FALSE,sep="")
# Variances
VAR=apply(DF,1,var)
# Order
pos=order(VAR)
# Print VAR and pos
VAR
pos
# ordered VAR
VAR[pos]
# top-2 highest VAR

Hi,
I have the following dataset (simplified for example).
__DATA__
300.35 200.25 104.30
22.00 31.12 89.99
444.50 22.10 43.00
22.10 200.55 66.77
Now from that I wish to do the following:
1. Compute variance of each row
2. Pick top-2 row with highest variance
3. Store those selected rows for fu

Dear list members,
How can I shade the background area of a zoo time series object between
specific dates?
eg.

"Close")

How can I produce the same plot but with a (say) red

I have 2 loops with 2 counters, say outer loop counter is X and inner loop

Baptiste,
the igraph ARPACK interface is quite experimental, and igraph includes
only the ARPACK files (converted to C) that it needs to calculate
some graph measures on sparse graphs. Btw. the development version
of igraph is a bit better in this respect, I can send you a link to
the developme
Dear all,
Thank you for the suggestions and pointers. It looks like I'll need
to do some interface with Fortran/C code. The igraph package seems to
provide an interface with ARPACK, albeit not with the options I need,
so it could be a good starting point.
Best regards,
baptiste

After mentioning the Into and the FAQs I went on to try to explain how to use a

Hi Paul,
Thanks for the answer. I temporarily did it with the subplot function
from the TeachingDemos package but I like this version much better.
Best,
