I'm trying to annotate a density plot and I'm using bquote to paste the sigma symbol next to the numeric text of the standard deviation calculation that I am performing. I have been able to successfully turn the sigma symbol and numeric output the color blue, but when I try to change the font of the text to bold, R doesn't seem to recognize the "font=" command in the same way

Hi everyone,I need you all help. I want to create few image in same diagram. For example, I wan draw two ellipse in same diagram. plot(ellipsePoints(2,5, alpha = 60), asp=1) and plot(ellipsePoints(2,5, alpha = 30), asp=1) How to display both ellipse together? both is different in angle. Thank you. -- Hemavathi Ramulu [[alternative HTML version deleted]]

Hi R users, I am trying generate the indices for locating a in the string it come from. Given the length of the string, it will take too long using the combn() for further comparison. I am wondering if R has any built-in function for this purpose. To make it concrete: this.substring="cc" this.string="ccc" start.location=1,2 end.location=2,3 Thanks in advance, Kevin

I am calculating some values that I am inserting into a data frame. From what I have read, creating the dataframe ahead of time is more efficient, since rbind (so far the only solution I have found to appending to a data frame) is not very fast. What I am doing is the following: # create data frame goframe = data.frame(goA = character(10), goB = character(10), value = numeric(10)) goframe[1,] =

I'm trying to annotate a density plot and I would like to have R calculate the standard deviation and place it in the plot next to the standard deviation symbol "sigma". I can successfully use the text command to paste "StDev =",round(sd(Data),digits=3)) on the plot. However, I have trouble when I want to replace "StDev" with the Greek symbol sigma (See code

Hello, I have made an R script that prepares a NONMEM dataset and I would like to start the NONMEM run right after the dataset is ready. I am using windows XP, R 2.9.1 and NONMEM 6. I have prepared a run.bat file that looks like this: ---------------------------------------- call K:\nmvi\NMdirectories.bat call K:\nmvi\nmfe6 "path\control.txt" "path\output.txt"

I am trying to fit a logistic model to my 10 year data (1999-2008) by year. Codes like below: Year <- c(1999: 2008) for(y in 1:length(year)) { file.input <- paste("C:\\", year[y], "\\data.csv", sep="") table <- read.csv(file=fileinput, header=TRUE, as.is=TRUE, na.strings=c("")) initial <- getInitial(percent ~ SSlogis(age, Asym,

Hi, I'm trying to randomize a sequence of trials for an experimental design. The trials consist of values for each of two factors. As is there are 30 combinations of the two factors, and I want them to be ordered randomly but with the requirement that for one of the factors, the value can never be the same as the previous value. I'm currently randomizing my dataframe by using:

Greetings, I'm trying to debug a simple two-line plot routine in R called test.R: cor(swiss) plot(swiss$Catholic, swiss$Examination) These commands work fine when typed into R. They also work fine when I invoke this routine by the following line into my terminal: R --slave < /Library/WebServer/Documents/gsa/test.R My ultimate goal is to send data to this R routine via a web
