similar to: glm with variance = mu+theta*mu^2?

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 everybody, I have a data set with a value and a status (positive or negative case) and I want make a ROC Analysis. So, with ROCR Package, I have got the ROC curve (True Positive Fraction [tpf] according 1-True Negative Fraction [1-tnf]). http://r.789695.n4.nabble.com/file/n4469203/01.png But, now I want a new graphic which show the sum of true positive fraction and true negative fraction

Dear R users, I am trying to fit a glm with a distribution free family, link = log and variance = constant*mu. I guess I have to use the quasi family but the choices of variance are restricted to constant or mu or mu^2..., I don't know the way to choose the variance that I need, i.e. constant*mu. If you have any ideas or advice, please tell me. Thanks, Laetitia Mestdagh Laetitia Mestdagh

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)

Buenas. Sé que en R hay multitud de datasets y me haría falta alguno que trataran de variables relacionadas con salud, sobre todo para aprender más acerca de cómo realizar una regresión logística binomial o multinomial. Gracias..

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")

Hi all, Cameron and Trivedi in their 1998 Regression Analysis of Count Data refer to NB1 and NB2 NB1 is the negative binomial model with variance = mu + (alpha * mu^1) yielding (1+alpha)*mu NB2 sets the power to 2; hence, variance = mu + (alpha*mu^2) I think that NB2 can be requested via negbin2<-glm(hhm~sex+age,family=quasi(var="mu^2",link="log")) Is

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?

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 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, 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

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

I received the following email note re: the vcdExtra package > A vcd update has shown that packages TIMP and vcdExtra are not > declaring their dependence on colorspace/MASS: see > > http://cran.r-project.org/web/checks/check_results_vcdExtra.html But, I can't see what to do to avoid this, nor understand what has changed in R devel. Sure enough, CRAN now reports errors in

Hello, In the past I have used "expression" to include greek letters in axis labels, but this time I need to include the greek letter as part of a legend. Basically, I need to create the following vector to rename the levels of a factor: c("Interferon-gamma", "IL-10", "IL-5"), where "gamma" obviously needs to be printed as the greek letter
