Re: [R] extract a subset of non-contiguous elements of a matrix
Hi You can pad some NA to the result before transforming it to required matrix but as Frede pointed out, what do you want to do with such result? tm.1=rbind(c(1,-3,2,-4), c(1,-3,2,-4),c(1,-3,2,-4)) xx-which(tm.1 0, arr.ind=TRUE) res-apply(xx, 1, paste0, collapse=,) dim(res)-c(3,2) res [,1] [,2] [1,] 1,1 1,3 [2,] 2,1 2,3 [3,] 3,1 3,3 tm.1 - matrix(c(11,22,33,-4), ncol=2) xx-which(tm.1 0, arr.ind=TRUE) res-apply(xx, 1, paste0, collapse=,) res-c(res, NA) dim(res)-c(2,2) res [,1] [,2] [1,] 1,1 1,2 [2,] 2,1 NA Regards Petr -Original Message- From: r-help-boun...@r-project.org [mailto:r-help-bounces@r- project.org] On Behalf Of carol white Sent: Thursday, June 19, 2014 3:46 PM To: Frede Aakmann Tøgersen; Bart Kastermans Cc: r-help@r-project.org Subject: Re: [R] extract a subset of non-contiguous elements of a matrix I realize that that the problem arises if there is a different number of negative numbers in the rows and columns of the original matrix.

[R] Rstudio: is it possible to create a document out of a working script?
Dear all, I am very happy with the new features introduced by Rstudio about how to create documents embedding R code. I would like to know though if there is some way to embed code from a working script into an Rmd document. I have several working scripts for which I would like to report the results, but I would like to avoid copy and paste the code in the Rmd document: the pipeline is still a work in progress, and it is likely that I will end up changing the code and parameters in the script. As you can imagine, having to copy and paste my code is prone error, and leads to a lot of code replication. I would like to avoid this, but couldn´t find a straightforward way so far. Thanks a lot in advance, of course if you have other advices, or comments on best practices for this sort of thing, I would like to hear them from you.

Re: [R] Rstudio: is it possible to create a document out of a working script?
How about simply using source() to call the script? If necessary, wrap bits of the script in functions, so you source a file with lots of functions, and then call the ones you need, as you need them.

Re: [R] Rstudio: is it possible to create a document out of a working script?
Hi Berend, sorry if it OT (though I think that the process is pretty much Rstudio independent, since what Rstudio does is wrap up knitr and their package Rmarkdown, but all the process can be run from the shell). Bob, so far this is what I do, but it is not ideal for two reasons: 1. I would like my report to be a step by step guide of what the script does. Wrapping the scripts in small functions, subscripts doesn´t help, because in the report what you would see is source(subscript.r), not the content of the subscript. 2. in a way I would need the exact opposite of what knitr and Rmarkdown do (at least by default). I would like to document my script in a way that can be run independently of the report and that, when neede, could use the comments to generate the report, similarly to how roxygen2 works when writing the documentation. Thanks a lot for the help, apologies again if this is OT (if so please remove the thread and I will ask in the the Rstudio support).

[R] random forest application
Hi All, Is anyone using random forest for predicting? Some people claimed that it will give more accurate result than decision tree. But considering it builds 500(by default) full trees, is it worth to use random forest to predict instead of decision tree? What typical applications of this algorithm? Thank you!

[R] Delaunay Graph, once again
Hello again,
After playing around with my current problem for some time, I have
once again returned to Delaunay Graphs and after banging my head
against the problem for some time I fear that I can't see the issue
clearly anymore and want to ask for some outside comments, to maybe
shake my thoughts loose again.
So, let me explain my project and then my problem:
I have a set of points, given as x- and y-coordinates and want to
create the adjacency matrix of the corresponding Delaunay Graph. I
have already removed duplicates in my set of points and to calculate
the matrix, I have hit upon the following procedure, which might not
be the most efficient, but I'm aiming for correct results and
simplicty first, before I can think about efficiency.
# x a vector of length n, containing the x-coordinates of my n points
#y: the same for the y-coordinates
library(deldir)
del - deldir(x, y) # calculating the tesselation
dels - del$delsgs[,5:6] # giving me a data.frame with 2 columns,
containing the indices of points connected by an edge in the Delaunay
Graph
adj - matrix(0, length(x), length(y)) # creating the empty adjacency matrix
for (i in 1:nrow(dels)){ # going through the rows of dels
adj[dels[i,1], dels[i,2]] - 1; # since the points in a row of dels
are connected, the matrix at that point is set to 1
adj[dels[i,2], dels[i,1]] - 1; # and this makes it symmetric
}
Now as I see it this should give me the adjacency matrix, right?
So let's come to my problem: The program I'm writing is a translation
of some Matlab-Code and so the results of both versions should be the
same, if at all possible. My adjacency matrix created in the above
mentioned manner however is not the same as the one created with
Matlab. The Matlab-Version uses algorithms based on Qhull, while I use
deldir as a library, could this account for the difference or have I
fundamentally misunderstood some part of the whole plan?
I hope the information is helpful and would very much appreciate any
pointers and thoughts on the matter.
Many thanks and all the best!
Raphael

Bob, so far this is what I do, but it is not ideal for two reasons: 1. I would like my report to be a step by step guide of what the script does. Wrapping the scripts in small functions, subscripts doesn´t help, because in the report what you would see is source(subscript.r), not the content of the subscript. 2. in a way I would need the exact opposite of what knitr and Rmarkdown do (at least by default). I would like to document my script in a way that can be run independently of the report and that, when neede, could use the comments to generate the report, similarly to how roxygen2 works when writing the documentation. http://rmarkdown.rstudio.com/r_notebook_format.html /Henrik Thanks a lot for the help, apologies again if this is OT (if so please remove the thread and I will ask in the the Rstudio support).

Re: [R] Principal component analysis with EQUAMAX rotation
Dear Wagner, I added the equamax rotation option to the psych package in version 1.4.6. This was requested by Sagnik Chakravarty, with a solution by Gunter Nickel.

[R] Loops to produce plots and leyend
I've tried several things but I don't manage to get this plot right. Any
help greatly appreciated!
I'm running a for loop to produce 4 plots at once. Each plot should only
show data points for a specific group (i.e. 4 plots for groups 1 to 4).
The coordinates of the points should be petal length and width. The
colour of these points should codify the species variable. Finally I'd
like to show a legend for the colours on these plots. It's important
that each species has a unique colour. Thanks you a lot for your input!

TestData-data.frame(ID=rep(1:10,each=10),TIME=rep(seq(0.1,1,0.1),10),VAR1
=rnorm(100),VAR2=5*rnorm(100),VAR3=10*rnorm(100))
Basically, I want to extract the maximum value from each ID for VAR1,
VAR2,
VAR3..
The way I can think of is
do.call(rbind,lapply(split(TestData,TestData$ID),function(x)x[which.max(x$
VAR1),'VAR1']))
and do this for each of the variables and put the results back. It's kind
of clumsy but OK for several variables. I have dozens of them. Is there a
better way to do it?
It would be ideal to produce the results like
ID VAR1.max VAR2.max VAR3.max 1 1.2828796 8.63276 15.051992 2
1.1870067

Re: [R] Delaunay Graph, once again
You are almost surely being bitten by the issue about which you
previously made inquiries to me, concerning the delaunayn() function
from the geometry package. (NOTE: ***PACKAGE***!!! Not library. A
library is a *collection* of packages.) The delaunayn()
function also uses the qhull algorithm. By default it treats some
triples of *collinear* points as triangles. This is probably causing
the discrepancy between the results.
Ergo it would seem best to use deldir() unless you *really want*
collinear triples to be considered as triangles --- and I can't see why
you would.
Your code for calculating the adjacency list is correct. (Except for the
fact that you put in unnecessary semi-colons --- this is R, not C ---
and for the fact that a comment runs over into the next line, causing an
error to be thrown when one tries to copy and paste your code.)
Try a toy example:
require(deldir)
set.seed(42)
x - runif(6)
y - runif(6)
dxy - deldir(x,y)
ind - dxy$dirsgs[,5:6]
adj - matrix(0, length(x), length(y))
for (i in 1:nrow(ind)){
adj[ind[i,1], ind[i,2]] - 1
adj[ind[i,2], ind[i,1]] - 1
}
adj
[,1] [,2] [,3] [,4] [,5] [,6]
[1,]010101
[2,]101110
[3,]010011
[4,]110011
[5,]011101
[6,]101110
ind
ind1 ind2
1 21
2 32
3 41
4 42
5 52
6 53
7 54
8 61
9 63
1064
1165
This looks right.
I'm not a Matlab user so I can't check what Matlab would give, but I'm
pretty sure the results would be the same in this toy example where
there are no collinear triples.
cheers,
Rolf Turner

Hello again,
After playing around with my current problem for some time, I have
once again returned to Delaunay Graphs and after banging my head
against the problem for some time I fear that I can't see the issue
clearly anymore and want to ask for some outside comments, to maybe
shake my thoughts loose again.
So, let me explain my project and then my problem:
I have a set of points, given as x- and y-coordinates and want to
create the adjacency matrix of the corresponding Delaunay Graph. I
have already removed duplicates in my set of points and to calculate
the matrix, I have hit upon the following procedure, which might not
be the most efficient, but I'm aiming for correct results and
simplicty first, before I can think about efficiency.
# x a vector of length n, containing the x-coordinates of my n points
#y: the same for the y-coordinates
library(deldir)
del - deldir(x, y) # calculating the tesselation
dels - del$delsgs[,5:6] # giving me a data.frame with 2 columns,
containing the indices of points connected by an edge in the Delaunay
Graph
adj - matrix(0, length(x), length(y)) # creating the empty adjacency matrix
for (i in 1:nrow(dels)){ # going through the rows of dels
adj[dels[i,1], dels[i,2]] - 1; # since the points in a row of dels
are connected, the matrix at that point is set to 1
adj[dels[i,2], dels[i,1]] - 1; # and this makes it symmetric
}
Now as I see it this should give me the adjacency matrix, right?
So let's come to my problem: The program I'm writing is a translation
of some Matlab-Code and so the results of both versions should be the
same, if at all possible. My adjacency matrix created in the above
mentioned manner however is not the same as the one created with
Matlab. The Matlab-Version uses algorithms based on Qhull, while I use
deldir as a library, could this account for the difference or have I
fundamentally misunderstood some part of the whole plan?
I hope the information is helpful and would very much appreciate any
pointers and thoughts on the matter.

[R] How to define a nonlin.function object for the spherical function to be used in the gnm model?
Hi,
I encountered with some difficulty in preparing the nonlin.function for the
gnm function. Please help me.
I want to use the gnm function in the gnm package to fit the following
spherical function
y = a + b (1.5*x - 0.5 *(x/c)) if x c
y = a + bif x = c
I understand that the fit.variogram function in the gstat function was
designed for fitting variogram, but it seems to be questionable because of
the normality assumption on the residuals. It is interested that whether
the fitted model would be changed as another distribution was assumed.
Seems to me, the gnm function in the gnm/R package could be used for the
this. However, I failed to customize a proper nonlin object for the
aforementioned formula after a few hours of try.
The following are my crappy code defining the nonlin object.
-
myfun-function(x) {
list( predictors = list(nuggest = .1, psill = 1, range=5),variables =
list(substitute(x)),
term - function(predLabels, varLabels) {
paste0(pred=, predLabels[1], +, predLabels[2], *(1.0 - exp(-,
varLabels[1], /, predLabels[3], ))
# paste0(pred[which(, varLabels[1], , predLabels[3], )]=,
predLabels[3], +, predLabels[2])
# paste0(pred)
}
)
}
class(myfun) - nonlin
-
In addition, I have also tried the gnls function in the nlme package but
did not find any parameters in function would allow to specify a
distribution for the residuals.
I appreciate any help, suggestion, comment on my question.Thank you very
much.
Best regards,
Zhiqiu
The following code are largely irrelevant to my question, but it could be
used to generate a semivarogram table for the analysis.
#The Sph model in SP analysis

Re: [R] Rstudio: is it possible to create a document out of a working script?
On Jun 20, 2014, at 2:40 AM, Luca Cerone wrote: Hi Berend, sorry if it OT (though I think that the process is pretty much Rstudio independent, since what Rstudio does is wrap up knitr and their package Rmarkdown, but all the process can be run from the shell). Bob, so far this is what I do, but it is not ideal for two reasons: 1. I would like my report to be a step by step guide of what the script does. Wrapping the scripts in small functions, subscripts doesn´t help, because in the report what you would see is source(subscript.r), not the content of the subscript. Have you looked at ?source and considered changing the associated option? getOption(verbose) [1] FALSE 2. in a way I would need the exact opposite of what knitr and Rmarkdown do (at least by default). I would like to document my script in a way that can be run independently of the report and that, when neede, could use the comments to generate the report, similarly to how roxygen2 works when writing the documentation. Thanks a lot for the help, apologies again if this is OT (if so please remove the thread and I will ask in the the Rstudio support). Cheers, Luca 2014-06-20 11:28 GMT+02:00 Bob O'Hara rni@gmail.com: How about simply using source() to call the script? If necessary, wrap bits of the script in functions, so you source a file with lots of functions, and then call the ones you need, as you need them.

I would like to know though if there is some way to embed code from a working script into an Rmd document. I have several working scripts for which I would like to report the results, but I would like to avoid copy and paste the code in the Rmd document: the pipeline is still a work in progress, and it is likely that I will end up changing the code and parameters in the script. As you can imagine, having to copy and paste my code is prone error, and leads to a lot of code replication. I would like to avoid this, but couldn´t find a straightforward way so far. Thanks a lot in advance, of course if you have other advices, or comments on best practices for this sort of thing, I would like to hear them from you.

Dear Wagner,
I added the equamax rotation option to the psych package in version
1.4.6. This was requested by Sagnik Chakravarty, with a solution by Gunter
Nickel.
Unfortunately, the version on CRAN is 1.4.5, but you can get the working
prerelease of 1.4.6 (1.4.6.20) from the alternate repository
http://personality-project.org/r/ (if using a Mac) or
http://personality-project.org/r/src/contrib/ if using a PC.
Thus,
p3e - principal(Thurstone,3,rotate=equamax) #will extract the first
three components and rotate them using equamax.
p3n - principal(Thurstone,3,rotate=none) #will give you the
unrotated 3 component solution
p3v - principal(Thurstone,3,rotate=varimax) #for the varimax solution
factor.congruence(list(p3e,p3n,p3v)) #compares the Burt/Tucker
congruence coefficients for these three solutions
Let me know if this does what you want.

Hello,
I need to do a principal component analysis with EQUAMAX-rotation.
Unfortunately the function principal() I use normally for PCA does not
offer
this rotation specification. I could find out that this might be possible
somehow with the package GPArotation but until now I could not figure out
how to use this in the principal component analysis.
Maybe someone can give an example on how to do an equamax-rotation PCA?
Or is there a function in another package that offers the use of
equamax-rotation directly?
Thank you for your help!

Hola. Parece que usas una distribucin derivada de debian, ya sea la misma debian, ubuntu, linux mint o similar. Puedes instalar R desde los repositorios del sistema con sudo apt-get install r-base Suele ser una versin de R bastante actual, pero si quieres la ltima versin en cran.r-project.org tienes instrucciones de como instalar R para estos sistemas. Bsicamente es aadir un repositorio en /etc/apt/sources.list y ya luego instalas R con sudo apt-get install r-base. A no ser, claro, que desees compilar R desde el cdigo fuente por algn motivo.

Tengo que hacer una curva ROC com unos datos que obtuve de hacer una macro de excel y aplicar unas reglas, y basicamente tengo que a partir de la variacion del tiempo y la velocidad del barco obtengo diferentes porcentajes de true positives (TP) y false positives (FP) y con eso deberia de construir una curva ROC. Dada mi ignorância en este tema, no se muy bien por donde empezar , estuve mirando los manuales de dos paquetes el ROCR y el pROC, alguien me recomienda alguno en particular? Yen los manuales el script del ROCR para hacer la curva era algo asi: library(ROCR) data(ROCR.simple) pred - prediction( ROCR.simple$predictions, ROCR.simple$labels) perf - performance(pred,tpr,fpr) plot(perf) ## precision/recall curve (x-axis: recall, y-axis: precision) perf1 - performance(pred, prec, rec) plot(perf1) ## sensitivity/specificity curve (x-axis: specificity, ## y-axis: sensitivity) perf1 - performance(pred, sens, spec) plot(perf1) Me parecio mas fácil de entender que el del otro paquete pero no se como aplicarlo a mis datos y si voy a obtener lo que quiero, si alguien me puede orientar un poco, agradeceria. Adjunto mis datos para tener una idea.
