NEW: CRAN/src/contrib/devel/mda_0.1-1.tar.gz I have made a first shot at porting the Hastie & Tibshirani mda package t= o R ... this is almost not tested at all ... but it works for the iris data and what else could a statistician be possibly interested in anyway = :-) All BRUTO stuff is missing because there are some unresolved symbols: R.binary: can't resolve symbol

Dear R users, I'm trying to perform flexible discriminant analysis (fda) with method bruto. I applied the fda function on my training data: bruto.fda <- fda (fda.formula,data=train.data) where fda.formula is: PRES ~ VA_D123 + VA_D124 + VA_D127 + VA_DARU + VA_DCAN + VA_DFON + VA_DLAP + VA_DRID + VA_DRIR + VA_VVEG + VA_WDIN + VA_DIF3 + VA_DIF4 + VA_DIF5 + VA_CAAC + VA_CABC +

Estimados usuarios de R: Tengo que hacer una desagregación temporal de una serie anual del producto interno bruto en trimestral. ¿Hay alguna forma de utilizar la librería en matlab de Quilis de desagregación temporal en R? La libreria se puede bajar de http://www.mathworks.com/matlabcentral/fileexchange/24438-temporal-disaggregation-library Saludos, Sebastián.

Dear helpers, I am trying to use the mda package downloaded from the R website, but the data set has missing values so I got an error message. Should I manually handle these missing values? I was trying to read the documents to specify any option related to missing values, but I did not find it. Please forgive me if I ignore something obvious. Thanks, Zhu Wang Statistical Science Department

Hola, Marta, Por lo que he podido ver tus datos ya tienen calculados las tasas de verdaderos y falsos positivos (TPR y FPR). También parece que los tienes ordenados por la variable FishSpeed y supongo que también por las que parecen marcas de tiempo. No necesitas ROCR porque con un simple plot te sale algo parecido a una curva. Eso sí, veo que son medidas repetidas en el tiempo para cada valor de

Hi, I'm looking to implement a regression with mixed terms. I have 2 biological endpoints for a dataset of n=77, one linearly related and the other fits a spline. I want to combine these two terms in a linear regression for prediction, then apply the model to a test set. this works fine, good r2 and I've graphed the spline. m1<-lm(y~x1,data=train) m2<-smooth.spline(x2,y); (spl)

I noticed that there is no generalised additive model functions in R (1.1.1) ... is there a package that implements them?

Hola a tod en s, Trabajo con datos de abundancia (número de individuos) por tallas (medidas al medio centímetro inferior) de diferentes especies de peces y mis datos base son el número medido de peces por talla. Necesitaría vuestra ayuda para transformar las distribuciones de frecuencias de talla a los datos brutos que las generaían. Es decir, pasar de algo como esto 8           1 8.5

Hi I just installed the gmodels package and the installation was successful but when I was trying to load the library I got an error (see below). Interesting, yesterday I wrote to the maintainer of RSQLite apckage because I got the same error. Does somebody knows what is going on ?? thanks, Mayte library(gmodels) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load

Hi there, I'm using R1.0.1 Windows 98. This file contains some inputs and an aov function code. Can someone check it for me? Somehow I got completely different answer when typing them in R and in Splus. Splus gives me this: > summary( Turnip.aov ) Error: Blocks Df Sum of Sq Mean Sq F Value Pr(F) Residuals 3 163.7367 54.57891 Error: Plots %in% Blocks

Muchas gracias, Javier, por tu explicación. Los dotos que manejo son todos datos linguisticos individualizados según variables geográficas y sociologicas; o sea que no hay que preocuparse demasiado por la peligrosidad de mis aseveraciones. El ejemplo lo hice a lo bruto para que se entendiera cómo se estructuran los datos, pensando que así no generaría distración sobre el objeto de mi problema. Lo

I have a list of groups of xy positions I want to set to 0 in an array full of 1s. When the assignments are done directly from the list, they are incorrect, while if I use a temporary array derived from the list the assignments are correct. The following example will hopefully make my problem clearer. The matrices z and zz are initialised with 1. The z and zz values at coordinates in

Hola Javier, si no estoy entendiendo mal, lo q deseo hacer no se trata de configurar los parametros SQL, sino solo de colocar un vector en el argumento VarTypes de la funcion sqlSave. El manual especifica esa opcion, pero no da ningun ejemplo de como usarla. *varTypes an optional named character vector giving the DBMSs datatypes to be used for* *some (or all) of the columns if a table is to be

Hello, We are looking to adjust the font size of the axis annotation on the graph that results from use of the metaplot() function. Metaplot seems to respond to cex and cex.lab to change those graphical parameters, but it doesn't respond to cex.axis. Is there a way to work around this by creating a customized x-axis, and if so, how? Thanks for all your help. Syntax is below. Best, Dawn

I've been using R actively for only the past few months under Mac OS X, but have found a few situations where I cannot get a package to load. This seems like the same situation reported recently on the thread "R-2.4.1 for MacOS X - languageR, acepack, Hmisc": > > library(Hmisc) > Error in dyn.load(x, as.logical(local), as.logical(now)) : > unable to load shared

Hi, I am trying to use piecewise linear regression to approximate a nonlinear function. Actually, I don't know how many linear functions I need, therefore, I want build an array of regression models to automate the approximation job. Could you please give me any clue? Attached is ongoing code: rawData = scan("c:/zyang/mass/data/A01/1.PRN", what=list(numeric(),numeric())); len =
