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 All: If I do have: x = (2, 4, 5, 5, 6, 4, 5, 2, 1) y = (9, 11.5, 12.5, 13, 14, 19, 20, 21, 22) I wanted to find a simple function in R which calculates the averages of X and Y for every 4 unit increase of Y. The results should look like: x = (4, 6, 3) #where (2+ 4+ 5+ 5)/ 4 = 4 and ... y = (12, 14, 20.5) #where (9+11.5+12.5+13)/ 4 = 12 and ... Thanks, Mohsen

Dear all, I want to design a histogram and I need to have the frequency at certain points. For example I have the following 2 columns: *X Y* 0.1 25 0.4 22 0.45 11 0.55 21 I want the chart to have 4 columns. First column is from 0.0-0.1 (on X) and frequency is 25. Next colum is wider and form 0.1-0.4 with 22 frequency. Next column is narrow with 11 frequency and the last column is

Hello all, I am doing a Likelihood Ratio (LR) test in my simulation and I have a vector LR values (each with 1 degree of freedom) at the end of my simulation. Can anybody tell me how I can write a 'R' code which gives me the p-value for each of those LR values. Thanks [[alternative HTML version deleted]]

Hello All: I was wondering why many plot options are not working with mhtplot. I could not find much info about this function on the web too. Any comments, any detailed manual ... Thanks, MJK [[alternative HTML version deleted]]

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?

Hello All, I am drawing a graph having 18 small graphs inside using par(mfrow = c(6,3)) command. My problem is how to specify the margins of the whole 18 graphs. I used par(mar=c(6.5, 6.5, 1.5, 1.5)) for each graph separately already but it does not left any margins for the 'mtext()' for the margins of the whole 18 graphs. Any comments please. Thanks, MJK [[alternative HTML version

Hello everyone, I am using the following program to get the p-value of some numbers (column 'LR' of the data.dat file). I want to write the 1st and 2nd column of the output file (data.out) as an integer while the program change them to double. Could anybody please tell me how I can write the code which writes the values of the first two columns as integer? Thanks library ('MASS')
