[R] Problem in adapting a script I have not written.

Dear R users, I'm new of R, thus I apologize in advance if my following question may result a little dumb, but I really need some expert advice. I have a problem in applying someone else's code to my data. The author's code works perfectly with the examples he provides, and it seems to me I am

[R] MACRO-LOOP in R

I am doing the data transpose with rename as shown below (step1 ~ step4) 1. Is any way in R similar to PROC TRANSPOSE used in SAS?2. How to use MACRO-LOOP to simplify the following procedure? THANK YOU FOR HELPS! # create data for test x<-data.frame(  a=c(1,2,3),  b=c("1","2","3")); x; str(x)#

Hi Dalila, is your function a part of a packacke or is it self-written? If you have the code it would be helpful to provide it. Frank __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help

[R] How to create an executable file from R GUI?

Re: [R] How to create an executable file from R GUI?

To give a full answer we need some more detail from you. For example what operating system are you on? what do you mean by "users click on it"? and at what point do you want them to click (after running R, when looking at the desktop, etc.) But to help get you started you may want to look at the

Re: [R] MACRO-LOOP in R

What a mess. Transposing factors is highly unlikely to lead to sensible results. Did you look at str( x123 ) as your example created it? x <- data.frame( a=c(1,2,3), b=c("1","2","3"), stringsAsFactors=FALSE ) x123new <- setNames( as.data.frame( t( x[ , "b" ] ) ), paste( "b", 1:3, sep="_" ) )

d[ 3 ] means indexing some vector-like object called "d" to extract the third value. (You really need to read the Introduction to R document that comes with R, particularly about indexing. There are actually four ways to do indexing that may come up as you read other people's code.) "d" is the

Re: [R] Problem in adapting a script I have not written.

Looks to me like the code was not tested for an AR value of 1. Works if I set it to 2. Could be an issue of failing to use the drop=FALSE option when indexing a matrix or data frame, but I don't have time to dig thorough the code to find out where. -- Sent from my phone. Please excuse my

The stats package is automatically installed when you install R. It's not available on CRAN because you already have it. Sarah On Thu, Feb 18, 2016 at 2:45 PM, T.Riedle wrote: > Dear R users, > I would like to install the stats package but I get the message > Warning in

Simon, Greg, That is the very reason why I've given up on Tck/Tk, in favor of shiny. The user interface opens up in a webpage, without opening the normal R console (it only opens a Terminal window). To exemplify, package QCAGUI has a function called runGUI(), and on Windows it's a simple matter

Re: [R] Reading a datetime vector

You are being rather scattershot in your explanation, so I suspect you are not being systematic in your troubleshooting. Use the str function to examine the data column after you pull it in from excel. It may be numeric, factor, or character, and the approach depends on which that function

Re: [R] Reading a datetime vector

Hi Doug, For one thing, you may be using the wrong format. Your example format has no seconds field. The other thing to watch is whether the data are in %m/%d/%Y or %d/%m/%Y date format. If the latter, you would probably get that error on dates like 19/02/2016. Jim On Fri, Feb 19, 2016 at 8:12

[R-es] Efectos de la regresion logistica

Buenas tardes a todos: Tengo un problema al interpretar los coeficientes de una regresión logística. Tengo varios grupos de variables predictoras que son indicadoras o dummy variables y representan todos los días de la semana y todas las horas del día. Al meter en el modelo, por ejemplo,

Re: [R-es] Efectos de la regresion logistica

En la formula de la regresión pon "-1": y ~ -1 + Dia Así te quitas la constante del modelo, y los efectos que estimas para cada dia ya no son relativos. En realidad, tu interpretación es correcta y interpretar el efecto de un día respecto al otro, es facil de comunicar. Un saludo. Olivier

Re: [R-es] Efectos de la regresion logistica

Hola: Gracias por tu respuesta. Ya había pensado en tu idea, pero si quitó el término independiente el modelo resultante es peor, tiene mucho menos porcentaje de acierto. Además en el conjunto de las variables horas del día sigue quitando una variable como me pasaba para días de la semana,

Re: [R-es] Efectos de la regresion logistica
