Dear R helpers: Sorry to bother for a basic question about model.matrix. Basically, I want to apply the dummy coding rule in a dataframe with complete factor levels to another dataframe with incomplete factor levels. I used model.matrix, but could not get what I want. The following is an example. #Suppose I have two dataframe A and B

Hi, I like the formatting and the appearance of lattice plots. But I have not succeeded in gettting the right format in my plots with the lattice package in one of my applications. In?the code shown below, I start by constructing a general data frame and show my attempts with the lattice package commands. After that, I use the graphics package and show the kind of plot that I want to get. I would

Dear community, I have now taken my R-file from lectures and intend to use it at home, but have a problem reading the Data from the file. I have installed and loaded the Package xlsReadWrite so far. I have also "Changed directory". This is what I have entered daten=read.xls("Daten A2") This is my Error-Message in its German original: Fehler in .Call("ReadXls",

Good morning, I am merging two datasets and I would like to save the non-matching rows in a separate file. The problem is how to retrieve the non-matching rows in R. Example: DATASET A code nomi A1 Franco A2 Mario A3 Andrea A4 Sandro A5 Luca DATASET B code book A1 Guerra e Pace A1 Storia di Roma A2 La coscienza di Zeno A4

I have used merge regularly and thought I understood how it worked, but I must not. I have two dataframes with identical colnames from two different experiments, TL01 and LC01. Each dataframe has a column named "Entrez.Gene", which I have converted to "as.character" just to make sure merge is not looking at factor levels. Because I have done some filtering, the Entrez.Gene

I am looking for a way to get a warning message immediately after an evaluation within a function. To get error messages you can use geterrmessage(). But I found no function that allows me to check for warnings. Five years ago this questions has been posted but I haven't found any answer. Thanks for any help. Peter Wolf ------------ For illustration purpose a simple example follows: you

Hi R user, I am new to R, and I have a very simple question for you. I have two matrix A and B, with internally redundant rownames (but variables are different). Some, but not all the rownames are shared among the two matrix. I want to create a greater matrix that combines the previuos two, and has all the possible combinations of matching rownames lines among matrix A and B. looking for the

Dear R-Users, I have a newbie-question about producing several plots with five variable pairs within in one code (loop). Problem: I define two objects, erveryone has five vectors (columns /variables): dimensionen <- data.frame(meinspss$attr_diff_gesamt, meinspss$finanz_diff_gesamt, meinspss$leist_diff_gesamt, meinspss$soz_diff_gesamt, meinspss$wert_diff_gesamt) gruppe <-

Hallo Zusammen, hatte gestern die Schnauze voll von Vista und habe mir daraufhin Ubuntu installiert. Bin also mit Ubuntu ?berhaupt nicht vertraut. Nun habe ich ohne Erfolg versucht, R zu installieren. Soweit ich der Anleitung folgen konnte habe ich es so wie auf http://wiki.ubuntuusers.de/R gemacht. Im Terminal kann ich R problemlos starten. Allerdings bei der Installation von

Hola Ruben, Sí precisamente es lo que comentas, en matemáticas no se suele llamar bucketización (este término se emplea más en informática) sino datos agrupados. Pero la idea es la que tu mismo dices. Respecto a las gráficas que has puesto, me han aclarado mucho sobre el tema, gracias. Si realizo lo mismo, por ejemplo con nbucket=1000 sigo obteniendo un p-valor de 1. Es decir, que casi le

I am a novice R user, and I am having difficulty understanding R's influence plots. I am trying to remove outliers from a particular variable, "sib." I am able to generate influence plots and further outlier information such as below (which is a shortened example). For my analyses, I end up excluding the points R refers to, 7, 18, 26, and 105. However, my question is, how can I

Hi, I use the code below to aggregate / cnt my test data. It works fine, but the problem is with my real data (33'000 rows) where the function is really slow (nothing happened in half an hour). Does anybody know of other functions that I could use? Thanks, Hans-Peter -------------- dat <- data.frame( Datum = c( 32586, 32587, 32587, 32625, 32656, 32656, 32656, 32672, 32672, 32699 ),

Dear R folks, wanting to compare different implementations of a solution I want to script it to iterate over the different implementations. Is there a way to do this in the R shell/command line? $ more /tmp/iterf.r f1 <- function(n = 100000, l = 100000) { z = n + l } f2 <- function(n = 100000,

Hi, is it possible to draw a box around the following barplot; using "box=TRUE" won't work. ---------- pc<-c(1,2,5,29,27) barplot(pc,ylim=c(0,30),yaxs="r",xaxs="r",ylab="Anzahl" ,names.arg=c("Mac","286er","386er","486er","Pentium I") ,axisnames=T,col="gray") ---------- Thanks in

Dear list Maybe someone can help with the following problem: I have a source file containing the following code for plotting: pdf(file = 'data/mario/boxplot.pdf') bwplot(sig100 ~ target | group, data = fish, main = 'Boxplot der Signale in 100 Zellen nach Gruppe', xlab = '', ylab = 'Anzahl der Signale') dev.off() pdf(file = 'data/mario/xyplot.pdf')

Hi, I am trying to identify duplicate values in a column in a date frame. The duplicated function identifies the duplicate rows in the data frame but it only does this for the second record, not both records. Is there a way to mark both rows in the data frame as TRUE? dfA$dups<-duplicated(dfA$Value) dfA Site State Value dups 929 VA 73 FALSE 929 VA 73 TRUE 930 VA 76 FALSE 930 VA 76 TRUE 931
