Re: [R] NULL dev.lis()
Dear Tom, Running R 3.2.2 on Ubuntu 15.04, if I run dev.list(), I get NULL. And I guess it is the expected behavior, as per the help page, it "returns the numbers of all open devices, except device 1, the null device". So, if I run x11() dev.list() I get X11cairo 2 HTH, Pascal On Mon, Nov 9, 2015 at 1:03 PM, Thomas Adams <tea...@gmail.com> wrote: > All, > > I have previous built R from source many times, generally, without > problems.

Re: [R] Simulating a time series with a given spectrum

I have looked at the R Time Series Task view, and have done a web search also, including an article to appear in the handbook of statistics on time series in R, but I don’t see anything offhand. There are some that will simulate state-space models or for given covariances matrices, but for a variety of reasons I would prefer simulating series with a given spectrum. Not sure it will totally answer your question, but if you are interested in simulating random time series having the same power spectrum but random phases as an input time series, you can visit this website (http://iri.columbia.edu/~vincent/matlab_function_version1/function_matlab.htm). There is a Matlab function called ebisuzaki (http://iri.columbia.edu/~vincent/matlab_function_version1/ebisuzaki.htm), which performs this. Of course, this implies you already have a time series of known spectrum. This function can easily be rewritten in R.

I usually need to compute P-values as following:
1. generate one sample (usually it is a matrix)
2. apply several methods (I already wrote a subfunction for each method,

3. compare the pvalues.
Since each method mentioned above takes long time (always different length
of time) to compute the pvalue, I am try to computing the pvalues parallel.
I want to assign computation of each method to each cores (I have intel
i7). Do you have any suggestion? I put the four subfunctions together as
main.fun=function(i,x,y,numper)
{
if (i==1) z=cca1(y,x,numper)
if (i==2) z=2
if (i==3) z=2
if (i==4) z=3
z
}
Each i indicates ith subfunction.
But I always get
task 1 failed - Lapack routine dgesv: system is exactly singular:
U[84,84] = 0
But when I only run `cca1` function (not using `foreach`), there is no
error.
The `foreach` is like this
pvalue=foreach(i=1:4,.combine=c,.packages=c(MASS,base)) %dopar%
main.fun(i,x,y,500)
The single computation is like this
pvalue=cca1(y,x,500)
I also put following in the top lines of my program
library(foreach)
library(doSNOW)
library(MASS)
cl=makeCluster(4,type=SOCK)
registerDoSNOW(cl)
**This looks like when I compute the `pvalue` separately not using
`foreach`, there is no error. But when I combine the subfuntions togeter
like `main.fun`, it has error.**

Re: [R] How to overlay contourplot of a dataset A and a levelplot of a dataset B?

Hi Pascal,
Right again. This seems to work for both and I think handles the problem
correctly:
if(is.null(ylim)) {
negy-any(height0,na.rm=TRUE)
if(negy) miny-min(height,na.rm=TRUE)*1.05
else miny-ifelse(ylog,min(height)/10,0)
ylim-c(miny,max(height,na.rm=TRUE)*1.05)
}
else {
miny-ylim[1]
negy-miny0
}
Remove the line:
negy-any(height0,na.rm=TRUE)
and modify the succeeding conditional clause as above. This will appear
in version 3.5-8.

I have some suggestions and/or confusions regarding the fa() function in the package: - The fa() function *doesn't account for Heywood cases* (communality greater than 1) and never ever throws out any error related to that which other softwares do. This is a serious and common issue in iterative factor analysis and hence should have been accounted for. - The fa() function doesn't provide equamax rotation in its rotation list and still if you specify *rotation=equamax*, it will run without throwing out any error and even mentioning in the result that equamax has been applied. But I have thoroughly compared results from *rotation=none* and *rotation=equamax* options and they are exactly same. *That means fa() is not doing the rotation at all and yet telling that it is doing that!!* I have even mentioned *rotation=crap* option just to check and surprisingly it ran(without any error) with the result showing: *Factor Analysis using method = gls* * Call: fa(r = cor_mat, nfactors = 4, n.obs = 69576, rotate = crap, fm = gls)* I hope you understand the severity of this bug and hence request you to correct this. - To my sense, there might be some problem with fm=ml and fm=pa options since the convergence issue should be with MLE method and not PA method but while running factor analysis with PA, I am getting the following warning: *maximum iteration exceeded* *The estimated weights for the factor scores are probably incorrect. Try a different factor extraction method.* If I compare the results of R and SAS,* I am getting convergence error for MLE in SAS whereas I am getting the same error for PA in R *!!

Dear Pascal,
Thanks for your reply. From your answer I perceived that if followings are
first three elements of a file
dput(ccc[1:3])
c(0.15912090241909, 0.167244642972946, 0.192471280694008)
then 0.15912090241909 is precipitation magnitude , 0.167244642972946 is
RSTN and 0.192471280694008 is flag value.Did i get it right?

Hello,
Some hints:
- for the year 1961, the total number of values is 27594000,
- there are 180 longitudes and 140 latitudes,
- there are 365 days,
- there are 3 variables,
Compare the total number of values and the result of (180 x 140 x 365 x 3).
The order is precip, rstn, flag, precip, rstn, flag,
precip, rstn, flag...
Hope this helps,
Pascal

Dear useRs,
A similar question has previously been asked by another user
(https://stat.ethz.ch/pipermail/r-sig-geo/2011-September/012791.html) but
i'll try to discuss it from another angle. Its about data reading. I am
trying to
read to read a data-set APHRO_MA_050deg_V1101R2.1961.gz from
http://www.chikyu.ac.jp/precip/cgi-
bin/aphrodite/script/aphrodite_cgi.cgi/download?file=%2FV1101R2%2FAPH
RO_MA%2F050deg.
I copied the command from previous post which is
ccc -readBin(APHRO_MA_050deg_V1101R2.1961, numeric(), n=1e8,
size=4, signed=TRUE, endian='little')
Followings are what I know about the structure of data set. The file
contains daily fields for 365 days. These daily fields are arranged
according to
the Julian calendar. Daily
fields (data arrays) contain information on the precipitation amount and
ratio of 0.05-degree cells containing a rain gauge. In the case the
given
file which is a
0.5-degree grid file, each field consists of a data array with longitude
by latitude dimensions of 180 x 140 elements for APHRO_MA.
The first element is a cell at the southwest corner centered at [60.25E,
14.75S], the second
is a cell at [60.75E, 14.75S], ..., the 180th is a cell at [149.75E,
14.75S], and the 181st is a cell at [60.25E, 14.25S]. The data files are
written in PLAIN DIRECT ACCESS BINARY. In each daily field, the array for
precipitation comes first, followed by
information on the rain gauge. Each element (both precipitation and
rain gauge information) is written as a 4-byte floating-point number
in little endian byte order. Users should swap the byte order to
big endian if necessary. There are no 'space', 'end of record', or
'end of file' marks in between. As it says that precipitation data is
in the
form of array which comes first, followed by the information on rain gauge,
how do I know which element is precipitation data and which is the
information of the rain gauge?Thankyou very much in advance

Hello, Your example is difficult to reproduce. Please 1. use dput() to attach data 2. indicate the package(s) you used. There are at least 3 packages with a som function. It seems you used RSNNS. And when I run your code, there is no unit.classif in datissimi datissimi$unit.classif NULL Regards, Pascal On 30 January 2014 01:39, Paola Tellaroli paola.tellar...@gmail.com wrote: I'm trying to compute the Silhouette value of a clustering partition done with SOM method using the function intCriteria of the clusterCrit package but it returns me a Nan value: somebody knows why?

Re: [R] clusterCrit package produces Nan
Hello, Please also reply to the list. I am not really familiar with this calculation, but it is maybe due to the fact you defined 8 nodes for your SOM, but your original data are only classified within 3 nodes. datissimi = som(test, grid=somgrid(xdim=2, ydim=4, topo='rectangular'), rlen=500, keep.data=TRUE) somissimo = datissimi$unit.classif unique(somissimo) [1] 2 4 8 intCriteria(test, somissimo, silhouette) $silhouette [1] NaN If I modify the shape of the Kohonen map: datissimi = som(test, grid=somgrid(xdim=3, ydim=1, topo='rectangular'), rlen=500, keep.data=TRUE) somissimo = datissimi$unit.classif unique(somissimo) [1] 1 2 3 intCriteria(test, somissimo, silhouette) $silhouette [1] 0.6478154 Hope this helps, Pascal On 30 January 2014 10:58, Paola Tellaroli paola.tellar...@gmail.com wrote: Hello Pascal, you're right, sorry.
