Re: [R-es] Weighted Likelihood
No das muchos detalles sobre porque quieres ponderar los datos, pero intuyo que es por el diseño. Si es así, la función svydesign del paquete te permite especificar bien la probabilidad de selección del dato (probs) en la muestra o de manera equivalente, o el sampling weight que puedes interpretar como la representatividad del dato en la población. Una vez especificado el diseño mediante esta función, puedes llevar cualquier análisis estandár de tus datos. Un saludo.

He mirado ya el paquete wle pero no me permite introducir los pesos mediante los cuales ponderar los datos.

[R] assign variables to function output
Hi! So I'm trying as the header suggests to assign the value(s) output by a function to a variable, say 'y' Problem is from what I gather any variables introduced within the function are contained and the only output I can get is return(value) which is awkward to work with. Any suggestions?

[R-es] Formulario Web
Hola: Tengo un absoluto desconocimiento de las posibilidades que ofrece R desde el punto de vista web así que agradecería que alguien me “encaminara” para un proyecto que me está rondando. El proyecto consistiría básicamente en montar una especie de formulario web al cual accederían distintas personas (colaboradores) repartidas por España. El formulario tendría una serie de datos precargados y el colaborador debería cumplimentar el resto de datos faltantes. Una vez cumplimentados todos los datos, estos se deben guardar en alguna estructura de datos (dataframe???) o algún tipo de BBDD para su posterior explotación estadística (esta sería la parte B del proyecto) En esencia el formulario debería poder: -Introducir valores de tipo texto o número así como valores de tipo combobox (valores pautados previamente),o lo que sería un factor en R. -Subir documentos (fundamentalmente fotos y pdf) asociados al registro que se está editando. -Ser capaz de mostrar a cada usuario únicamente los registros que tiene que rellenar puesto que los registros se distribuirán entre los colaboradores por criterios geográficos . De esta manera un colaborador residente en Madrid solo “vera” los registros relativos a Madrid y no los del resto de provincias. -Mostrar mapas, gráficos, fotos “incrustados” en el propio formulario web a medida que se van introduciendo datos y/o subiendo documentos. Lógicamente la mejor forma de hacer esto es usando lenguajes de programación web (html, java, php etc) asociados a gestores de bases de datos (SQL server, mySQL etc) pero mi desafío consiste en hacer TODO el proceso (Tanto la captura como la explotación de los datos) dentro de R, aun cuando puedan usarse sistemas auxiliares conectados a R.

[R] function as variable name - probably better error message
Hi The following code works as expected: list(plot=Not any more!) , | plot - Not any more!) | [1] Not any more! ` But for this I get an error: , | function - Not any more! | Error: unexpected assignment in function - ` The error message is quite cryptic and does not help much further. Would it be possible to provide a more useful error message in this case that (presumably) function is a reserved word? Along the same lines - is there a list of reserved words which can not be used in R as variable names (not even as elements in a a list())? This is not a huge problem, but it cost me a few minutes of figuring out. Thanks, Rainer -- Rainer M.

Binaries for various platforms will appear in due course.

R_SHELL, the preferred way to select a non-default shell, can be used instead. * Some unusual arguments to embedFonts() can now be specified as character vectors, and the defaults have been changed accordingly. * Functions in the Summary group duplicate less. (PR#15798) * (Unix-alikes.) system(cmd, input = ) now uses 'shell-execution-environment' redirection, which will be more natural if cmd is not a single command (but requires a POSIX-compliant shell). (Wish of PR#15508) * read.fwf() and read.DIF() gain a fileEncoding argument, for convenience. * Graphics devices can add attributes to their description in .Device and .Devices. Several of those included with R use a filepath attribute. * pmatch() uses hashing in more cases and so is faster at the expense of using more memory. (PR#15697) * pairs() gains new arguments to select sets of variables to be plotted against each other. * file.info(, extra_cols = FALSE) allows a minimal set of columns to be computed on Unix-alikes: on some systems without properly-configured caching this can be significantly faster with large file lists. * New function dir.exists() in package base to test efficiently whether one or more paths exist and are directories. * dput() and friends gain new controls hexNumeric and digits17 which output double and complex quantities as, respectively, binary fractions (exactly, see sprintf(%a)) and as decimals with up to 17 significant digits. * save(), saveRDS() and serialize() now support ascii = NA which writes ASCII files using sprintf(%a) for double/complex quantities. This is read-compatible with ascii = TRUE but avoids binary-decimal-binary conversions with potential loss of precision. Unfortunately the Windows C runtime's lack of C99 compliance means that the format cannot be read correctly there in R before 3.1.2. * The default for formatC(decimal.mark =) has been changed to be getOption(OutDec); this makes it more consistent with format() and suitable for use in print methods, e.g. those for classes density, ecdf, stepfun and summary.lm. getOption(OutDec) is now consulted by the print method for class kmeans, by cut(), dendrogram(), plot.ts() and quantile() when constructing labels and for the report from legend(trace = TRUE). (In part, wish of PR#15819.) * printNum() and hence format() and formatC() give a warning if big.mark and decimal.mark are set to the same value (period and comma are not uncommonly used for each, and this is a check that conventions have not got mixed). * merge() can create a result which uses long vectors on 64-bit platforms. * dget() gains a new argument keep.source which defaults to FALSE for speed (dput() and dget() are most often used for data objects where this can make dget() many times faster). * Packages may now use a file of common macro definitions in their help files, and may import definitions from other packages. * A number of macros have been added in the new share/Rd directory for use in package overview help pages, and

Would it be possible to provide a more useful error message in this case that (presumably) function is a reserved word? Along the same lines - is there a list of reserved words which can not be used in R as variable names (not even as elements in a a list())? The R Language Definition lists the reserved words (see section 10.3.3). It oversimplifies things, saying they can't be used as variable names, when in fact almost any string can be used with proper quoting. For example, both of these work: function - Not any more! `function` - Not any more! Duncan Murdoch This is not a huge problem, but it cost me a few minutes of figuring out.

Re: [R-es] Formulario Web
Estimado Miguel Es posible lo que dices, pero ¿tienes un servidor para instalar la parte de R?, si lo tienes ¿cuántos recursos? Me refiero a lo siguiente, puede ser que su trabajo esté excelente, pero los recursos del servidor al procesar R tengan un desmedro en la calidad (velocidad) http y de base de datos, creando una experiencia mala para el usuario. Hay alternativas, cada vez hay más web R, desconozco la solución recomendable hoy en día, sin embargo creo que hay que tener muy en cuenta el servidor, y ese factor puede ser de mucho peso en caso de ser deficiente. Shiny , es conocido, o por lo menos es una opción de moda por decirlo de alguna forma, sin embargo creo que podría escribir R desde casi un obsoleto cgi-bin.

Re: [R] melt function chooses wrong id variable with large datasets
Thanks, indeed norm should be in the same group as as the months. everything works fine when the number of data is quite small, but with big datasets (15 000 values) things seem to go wrong and I can't explain why. It puts norm as an individual column in stead of in the group of months as it does when the dataset is small.

I would like like to compare this data, so I transform my dataset with the melt function to get 1 column of data and 1 column of ID variables, then I can apply different statistical tests. With small datasets this works great, the melt function automatically chooses the name in row 1 as ID variable and melts the data, thus giving me a matrix with all ID variables in column one and the data accordingly in column 2. With this big dataset however it chooses the whole first column as ID variables in stead of the first row. Is there a reason why this happens and how can I make sure the first row is chosen as ID variabele and the lower rows as data? If I specify that I want the first row to be the id variable I also get error. melt(dataset,id.vars=dataset[1,], na.rm=TRUE) Error: id variables
Re: [R] Question with uniroot function
Hi Jeff,
Thanks for the reply. I am aware that the sign needs to be different at
the ends of the starting interval.

Is there a way to set the right end point ( (the upper argument in the
uniroot function below) as the point where the function takes on its
minimun, for example my function f1 below?
Thanks very much!

u2 - 4

x - seq(-20,20, by=0.1)
y - numeric(length(x))
for (i in 1:length(x)){y[i] - f1(x[i],p1=0.15,lambda=0.998)}
plot(y ~ x, ylim=c(-1,1))
abline(h=0)
a - uniroot(f1, lower =-10, upper = 0,
tol = 1e-20,p1=0.15,lambda=0.998)$root

You really need to read the help page for uniroot. The sign needs to be
different at the ends of the starting interval. This is a typical
limitation of numerical root finders.

Re: [R] function as variable name - probably better error message
Actually, to split a few hairs, I think the documentation is essentially
correct.
Reserved words are not the same as quoted strings. You cannot use them in
syntactically the same way that you usually use variable names, as unquoted
strings in expressions. They can BE variable names, or more precisely: object
names. In fact they often are; you get in deep trouble if you redefine `for`,
`function`, or `if` -- as functions, at least. That goes for things like `{`
too, by the way.

But for this I get an error:

The error message is quite cryptic and does not help much further.
Would it be possible to provide a more useful error message in this
case that (presumably) function is a reserved word?
Along the same lines - is there a list of reserved words which can
not be used in R as variable names (not even as elements in a a
list())?
The R Language Definition lists the reserved words (see section
10.3.3). It oversimplifies things, saying they can't be used as
variable names, when in fact almost any string can be used with proper
quoting. For example, both of these work:
function - Not any more!
`function` - Not any more!
Duncan Murdoch
This is not a huge problem, but it cost me a few minutes of
figuring out.

awkward to work with. Any suggestions?

Javier, Miguel: Efectivamente hay maneras infinitamente más eficientes a la hora de montar el proyecto con soluciones específicas de web. Pero en este caso como lo que pretendo, fundamentalmente, es profundizar en lo que Javier mismo ha denominado webR por lo que no contemplo esas soluciones especificas (si acaso solo como apoyo a R). Básicamente se trata de hacerlo todo con R, aun sabiendo desde el principio, que seguro que no es la mejor forma de hacerlo (sobre todo en lo referente a sencillez y rendimiento). Llevando el caso al extremo, seria como intentar hacer un procesador de textos utilizando Excel, la mayoría diría pero si para eso ya tienes Word y mil aplicaciones más adecuadas y mi respuesta seria ya, lo sé, pero es que yo quiero hacerlo con Excel aunque no sea ni el mejor, ni el más rápido ni el más bonito.

No veo demasiado problema con el tema del servidor. Las opciones son dos: o lo tienes in situ (con lo cual habrás hecho una valoración de qué recursos te hacen falta, cómo vas a implementarlo y cómo vas a mantenerlo, como con cualquier otro servicio web) o lo implementas en la nube (idem que el caso anterior con la salvedad de que hay ciertos aspectos que subcontratas - pagas por ellos y te despreocupas-). Yo soy más partidario de la segunda opción y montar un buen VPS, pero para gustos En el caso concreto del escenario que plantea José Luis (que es el que nos ha llevado hasta aquí), la solución pasa por montarlo todo con R (según sus especificaciones) y, así, creo que Shiny es una muy buena alternativa.

Me refiero a lo siguiente, puede ser que su trabajo esté excelente, pero los recursos del servidor al procesar R tengan un desmedro en la calidad (velocidad) http y de base de datos, creando una experiencia mala para el usuario. Hay alternativas, cada vez hay más web R, desconozco la solución recomendable hoy en día, sin embargo creo que hay que tener muy en cuenta el servidor, y ese factor puede ser de mucho peso en caso de ser deficiente. Shiny , es conocido, o por lo menos es una opción de moda por decirlo de alguna forma, sin embargo creo que podría escribir R desde casi un obsoleto cgi-bin.

[R] vi[m] editing of past commands in R command line
When I use bash + readline and ~/.inputrc contains editing-mode vi, I can press v to switch to from the command line editing to a full vi session editing of a command. This doesn't seem to happen in R. Is there a configuration setting/file that I can set to get this behaviour? Furthermore, when using bash, the fc command allows me to edit the history of commands, and when I exit the editor, all the remaining (and likely modified) commands are submitted to the bash shell as if I typed them at the prompt. Is there a way to get similar functionality in R? __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Obfuscate AES password
Thanks Robert, but is not exactly what I need :) I am simply trying to find a way to encrypt some data in a way that doesn't require the user to type any password (if not only the first time) but that is secure enough in a multi-user environment. E.g. I do not want super user to be able to access my data because they can read the AES key. Hope this is a bit clearer, Thanks a lot for your help!

Re: [R] Extracting xml data to data frames
No attachment : R-help is rather fussy about the files it will accept. You are probably okay with .txt .pdf, or png but even .csv is likely to get stripped. The best way to supply data is by using dput() . Type ?dput for information or have a look at http://adv-r.had.co.nz/Reproducibility.html for some hints.

Ideally I need them in .csv files. Each file (an example is attached) contains up to 8 tables of information about transport operators and routing information.

I'm new to handling xml data and to the xml package so I don't really know what I'm doing, this is my first stab at using the xml package. So far the workflow goes something like this. #get the file doc=xmlTreeParse(cen_18-23-D-y11-2.xml) top=xmlRoot(doc) #look at the names top=xmlRoot(doc) #pick one of them to use, in this case the forth one, 'routes', a table of information about this particular bus route. using some code from another forum post, I can get a data.frame with the info i need in it.

ear community,
This is to kindly request for your help.
I have an error from regression of values in one stack with another
# s1 and s2 have 720 layers; coefficients[2] is the slope
### script
rstack1 - stack(s1,s2)
s - stack('D:/Correlation/rstack.tif')
fun - function(x) { lm(x[1:360] ~ x[361:720])$coefficients[2] }
x1 - calc(s, fun)
I get the following error:
Error in .calcTest(x[1:5], fun, na.rm, forcefun, forceapply) : cannot
use this function
Many thanks for your help in sloving this problem

You really need to read the help page for uniroot. The sign needs to be
different at the ends of the starting interval. This is a typical
limitation of numerical root finders.
