Hello All: Can anybody tell me what is the problem with my program please. I have an error message as appears below. My program is: ifn <- "Jul08_09.LM" data <- read.table(ifn) ofn <- "Jul.png" bitmap(ofn, type = "png256", width = 30, height = 30, pointsize = 30, bg = "white",res=50) par(mar=c(5, 5, 3, 2),lwd=5)

Hi, I wanted to compute the value of the function ifn at certain values of n. But I am receiving the following error when I was using the following code(given at the end). Error: evaluation nested too deeply: infinite recursion / options(expressions=)? I feel that since the function Grx is recursively related, perhaps making the code too complicated too handle. Can anyone let me know if

Hello all, I have this simple barplot code: ifn <- "id.dat" dat <- read.table(ifn) ofn <- "id.png" bitmap(ofn, type = "png256", width = 30, height = 30, pointsize = 30, bg = "white",res=50) par(mar=c(5, 5, 3, 2),lwd=5) par(cex.main=1.6,cex.lab=1.6,cex.axis=1.6) names(dat)<-c("NumberOfPeople","Average")

Hello there, I have the following info in MyData: 01 0.40 02 0.40 03 0.40 04 0.35 05 0.34 06 0.33 I want to read them using the following code: ifn <- "MyData" dat <- read.table(ifn) names(dat1)<-c("Code","M") names(dat2)<-c("Code","M") I want to have the first three lines in

Hello All: I am having the following data file named "data.dat" Number of people Number of pets Age of trees ifn <- "data.dat" dat <- read.table(ifn) colnames(dat)<-c("Variables") I want R to read all these in a string but when I ask R to read these, it gives me error because there more than one word in each line. Any comments to solve this problem?

Hi all, I am a beginar user of R and try to do some CART analysis with it. With "rpart" we can get several terminals and draw it in the TREE plot. Now I am trying to draw a plot like this: x-axis is each terminal's value, and y-axis is those observe values. Does anyone has idea what gramma should I use? Thanks in advance.

Hi, Could someone please let me know how to plot greek letters in italic. text(0,14,expression(italic(rho)[italic(f)])) only plots the f in italic and text(37,40,expression(italic(rho))) doesn't plot rho in italic. I have checked demo(plotmath), ?plotmath, FAQ, and the archives 2004-2006 without finding the answer. I'm using R 2.1.1. and Windows XP. Thanks! Tord -- Tord Sn?ll

Hello All: Could anybody tell me please what is the meaning of this error message: ESP Ghostscript 815.02: Unrecoverable error, exit code 1 Error in plot.xy(xy, type, ...) : ignoring SIGPIPE signal Calls: plot -> plot.default -> plot.xy Execution halted My code has to go to 18 loops for three times and in each loop it has to read a file which is 100-300 Megs. It always crashes at loop 14

Hi, I would like to add a two-lines label consisting of: "Delta word1\n word2" (with Delta being the actual greek letter). However, when I try "expression(paste(Delta,"word1\nword2"))", I obtain the following display: "word1\n Delta word2". Do you have any idea on how to obtain the desired display? Thank you for your help! Sebastien [[alternative HTML

Hi everyone. I'm trying to use small letter phi in a graph produced in R. However, the small letter phi does not look as it should. In fact, it looks like this: http://r.789695.n4.nabble.com/file/n3963311/Untitled.png instead of what is here http://en.wikipedia.org/wiki/Phi Here's the code I use: expression(phi [1]) Anyone has an idea?

I have a small problem with R graphics output. When I use the lattice package and CairoPDF to generate publication quality graphs I often use the expression to create an axis title that has microlitres or micrometers as a unit. I use something like the following 'expression(paste("Length (", mu,"m )"))' as an argument to the xlabel function. The command works but the mu

Hi there, yet on the topic of greek letters and pdf plotting: when I run the following code pdf(file="temp.pdf") mu=seq(from=-pi, to=pi, length=100) plot(mu, sin(mu^2), type="l", xlab=expression(mu%in%(list(-pi,pi))), ylab=expression(sin(mu^2)), main=expression((list(mu,sin(mu^2))))) dev.off() I get a "proportional to" symbol in place of a

Hello. I am trying to get my axis label to read as follows (The symbol) Delta AUC blah blah... then below it...(some other text) The problem is the Delta symbol shows up beside the "(some other text)" rather than the "AUC". Does any one know how I can get the Delta to remain beside AUC? Here is the actual command should you care to look at it. par(mar=c(8,8,4,4))

I am unable to get a my Draytek working with our Asterisk server. I can make/recieve calls but get no audio. I have tried the various codecs at the Vigor end but still getting nothing. I looked at sip debug (below) but am new to Asterisk and don't really know what I am looking for. Asterisk works fine with XLITE so I know my installation is ok. Sip read: INVITE

Dear fellows, I am a novice in R. I would like to combine a matrix and a vector. Assume that we have the matrix a and the vector b with same length of column. a<-matrix(seq(1:10),nrow=2,ncol=5,byrow=TRUE) a= 1 2 3 4 5 6 7 8 9 10 b<-t(c(11,12,13,14,15)) b= 11 12 13 14 15 Then, I want to combine a and b as follows. c= 1 2 3 4 5 6 7 8 9

Hello, I am trying to write math-type on a plot. Due to space limitations on the plot, I want 2 short expressions written on top of each other. It is certainly possible to write them in two separate calls, but that involves fine-tuning locations and a lot of trial and error (and I'm trying to write a general purpose function). Here's where I've gotten to:

Hi Dieter and R community: I tried both of these three versions with ylim as suggested, none work: I am getting only single (pch = 16) not overlayed (pch =3) everytime. *vs 1* require(lattice) xyplot(Sepal.Length ~ Sepal.Width | Species , data= iris, panel= function(x, y, subscripts) { panel.xyplot(x, y, pch=16, col = "green4", ylim = c(0, 10)) panel.lmline(x, y, lty=4, col =

Hi, R-Helpers, I would like to ask about multiple graphs in one figure. I tried to execute the following codes. xlim <- c(1,100) ylim <- c(1,4) plot(NA, xlim=xlim, ylim=ylim) > x <- c(1:100) for(j in seq(1,10,by=1)) { y <- j*x^2+log(j) lines(x, y) } In the above codes, I had to arbitrarily set up the coordinate range of the figure in advance before
