Dear R-users, I have a dataset with categories and numbers. I would like to compute and add cumulative numbers to the dataset. I do not understand the structure of by(...) or tapply(...) output enough to handle it. Here a small example -------------- d<-expand.grid(a=1:5,b=1:3,c=1:2) d$n = 10 * d$a + d$b +0.1* d$c Sn<-by(d$n,list(d$a,d$c),cumsum) str(Sn) --------- List of 10 $ : num

L.S., With the code below, on the Windows screen the line types in the key show as solid and dashed as in the graph, and in the pdf file they show as solid in the key and solid and dashed in the graph. I would not expect that, but may be I get something wrong. Gerrit. ------- library(lattice) # pdf("pietje.pdf") x<-0:10 xyplot((x^0.5)+(x^0.75)~x,type="o",lty=c(1,2),

Hallo, Im trying to find out how to tabulate frequencies of factors when the data have a frequency variable. e,g: i<-rep(1:5,2) j<-rep(1:2,5) N<-10*i+j table(i,j) gives a table of ones as each combination occurs only once. How does one get a table with the corresponding N's? Thanks! Gerrit. -- Gerrit Draisma Department of Public Health Erasmus MC, University Medical Center

Hallo, What is the right way to get vertical bars in a barchart? For instance barchart(VADeaths, key=simpleKey(colnames(VADeaths),points=F,rectangles=T)) gives what I need, only I would like the bars to be vertical. But barchart(VADeaths,horizontal=F, key=simpleKey(colnames(VADeaths),points=F,rectangles=T)) does not give what I need, and I do not understand how to change the

Hallo, I am trying to define expectation as an integral and use uniroot to find the distribution parameter for a given expectation. However I fail to understand how to define properly the functions involved and pass the parameters correctly. Can anyone help me out? Thanks, Gerrit Draisma. This what I tried: ======= > # exponential density > g <- function(x,lambda){ lambda

I'm rsyncing from an linux box to a win2k box with a precompiled version of rsync for win2k. durring the procces he gives me a lotte of the following errors (with different filenames): rename realother/Maildir/cur/.1005882149.8001_0.nyx.wildape,S=3080:2,.001002 -> realother/Maildir/cur/1005882149.8001_0.nyx.wildape,S=3080:2, : No such file or directory I user the command: rsync -cru

Hallo R-users, I do not understand how to specify the correct line and symbol types in the legends of a lattice xyplot. This is what I tried, but the line types and symbol in the graph are not seen in the legend. Any help is appreciated. Thanks, Gerrit. library(lattice) s<-rep(1:3,len=10) x<- 1:10 y<- x+s+rnorm(10) d<-data.frame(s,x,y) xyplot(y~x, groups=s,data=d,

Package: xen-utils-common Version: 4.1.2-3 Severity: normal When configurating a duplicate custom vifname for interfaces in the Xen dom0 that are added to a bridge (which is obviously a configuration error), the hotplug scripts fail silently to rename the new vifX.0 to the custom vifname, if it's already existing. The result of this, is that the domU will start normally, but no network

I am looking for the following simple question. I have a data frame with names and numbers, divided in categories. I would like to produce a text file with page breaks, listing the names and numbers by category, and totalling the numbers. Example: Name<-LETTERS[1:6] Score<-rep(5:8,length.out=6) Form<-rep(1:2,each=3) x<-data.frame(Name,Score,Form) This gives approximately

I have installed ubuntu edgy with latest patches and wine 0.9.29. I use a application called osfinancials, www.osfinancials.org, this installs, but does not run. Strangly enough, it does run when using suse and wine, so it seems to be related to the combination of ubuntu edgy and wine. When I run the exe, osfinancials.exe, I get the following errors: sudo wine osFinancials.exe

Hello, I would like to be able to update an existing column in a dataframe, like this... data$score[data$type=="1" & data$year=="2001"]<-data$score * 0.111 data$score[data$type=="1" & data$year=="2002"]<-data$score * 0.222 data$score[data$type=="1" & data$year=="2003"]<-data$score * 0.333 ...but, if possible,

Hi all, I have a vector xm say: xm = c(1,2,3,4,5,5,5,6,6) I want to return a vector with the corresponding probabilities based on the amount of times the numbers occurred. For example, I should get the following vector for xm: prob.xm = c(1/9, 1/9, 1/9, 1/9, 3/9, 3/9, 3/9, 2/9, 2/9) Any help greatly appreciated. -- Thanks, Jim. [[alternative HTML version deleted]]

Hallo, I have a dataset with one or two columns with character data and the rest with numeric data. Using latex.table from the quantreg package produced a table, but I cannot set the decimals. For instance: --- > x<-data.frame(Name=c("Jan","Piet","Jan"), V=c(1,2.991,3)) > latex.table(as.matrix(x),file="x",caption="x") >
