Re: [R] Installing package QRMlib

2012-02-28 Thread Pfaff, Bernhard Dr.

Dear all:

well, what Duncan has suggested would work in principle. However, the 
dependencies of QRMlib as contained in the archive have been deprecated and the 
package maintainer (cc'ed to this email directly) is pretty close to a 
re-release of his package on CRAN, whereby primarily the outdated package 
dependency to fSeries is changed to timeSeries. 
Hence, before grabbing the deprecated package dependencies on R-Forge and 
install these, it might be worth waiting for the re-submittance of QRMlib to 
CRAN, given that it will be made in due course. Scott, do you have any further 
information whence QRMlib will be made available again on CRAN?

Best,
Bernhard

That should be type=source, and that should solve the problem, assuming 
Deepan has the necessary tools installed.  If not, he can get them from CRAN in 
the bin/windows/Rtools directory.

You have several options. Try function nipals in packages ade4 and plspm.
Also look at package pcaMethods (on Bioconductor), where you will find a
full range of options for carrying out principal component analysis using
matrices with missing values.

[R] Conditional density estimation in R and integration

2012-02-28 Thread fReak



Hey there,


I have the following problem: 

I need to carry out a nonparametric conditional density estimation -- pretty
much what can be achieved using the np package. However, I need to be able
to use the output of the np package in such a way that i get a continuous
function as output, which can be integrated on any given interval between
-Inf and Inf. This integration will of have to be across mutliple dimension
since I am working with a conditional pdf. Any advise on how to accomplish
this? I suspect that I need to use some kind of interpolation package to get
from the output of the np package to getting a function that can be
integrated, but that is exacly where I am stuck

Thanks for your help!

[R] macro function

2012-02-28 Thread mrzung

hi, 

I know how to use the for loop function like: 

for(i in 1:ncol(mat)){ 
mat[i]-b[i,2] 
} 

but, in this case 

r1-b[1,1] 
r2-b[2,1] 
r3-b[3,1] 
r4-b[4,1] 

* 
* 
* 

r3002-b[3002,1] 
r3003-b[3003,1] 

- must make vectors 

how should I make a efficient code for that? 

Is there anything in R like SAS MACRO function?

Re: [R] Error message: object of type 'closure' is not subsettable

2012-02-28 Thread Aparna Sampath

Hi All

I am trying to use the unlist() in R to a list variable.  The following
statements are within a function. 
{
denominator - sqrt(s1 / res.em1$n + s2 / res.em2$n) 
 returnValue - l2 / (denominator + 11)
  attr(returnValue,numerator) - l2
  attr(returnValue,denominator) - denominator
  returnValue
}

And when I try to unlist the variable returnValue

 numerators - unlist(testStatistics[numerator,])
  denominators - unlist(testStatistics[denominator,])

I get the following error: 

Error in testStatistics[numerator, ] : 
  object of type 'closure' is not subsettable

I read some threads in R help on this error and they had asked to check if
we are using the right datatype to the right function. But in my case it is
pretty straightforward since I just list it in one function and try to
unlist it later. Any suggestions?
Thanks for the help :)

That's quite a general request. I think you should try to formulate a
specific question.

Have you read the posting-guide? http://www.R-project.org/posting-guide.html

Also, I don't think the list accepts attached files.

Re: [R] macro function

2012-02-28 Thread Joshua Wiley

Hi,

There is not anything really like macro functions in R (and honestly,
that is probably a good thing).  Most the times I have seen people
generating thousands of variables (vectors in your case) it is due to
a lack of understanding how lists can be utilized to simplify code.
If you give us some context on what all these vectors will be used
for, we may be able to suggest an easier way to accomplish your goals.

If you must create vectors:

sapply(1:3003, function(i) {
  assign(paste(r, i, sep = ''), rnorm(1), envir = .GlobalEnv)
})

or with a for loop:

for (i in 1:3003) {
  assign(paste(r, i, sep = ''), rnorm(1), envir = .GlobalEnv)
}

HTH,

Josh

Re: [R] Error message: object of type 'closure' is not subsettable

2012-02-28 Thread Joshua Wiley

Hi Aparna,

Can you please post a reproducible example? It is difficult to
provide much concrete help without having testStatistics. One thing
you might try is looking at:

str(testStatistics[numerator,])

is it actually a list? If it is not (most likely given the error) and
it is supposed to be, you need to figure out what aspect of the
generation of it is going awry.

Cheers,

Josh
