...would like to convert this matrix to a binary one according to the minor allele frequency. For non-geneticists: I want to have a binary matrix for which in each row the 0 stands for the less frequent character and 1 for the more frequent character. Thanks for any suggestions.

...ring the run. I would like to run this program from R and as far as I have seen system() does not handle manual options (?). Is there thus a way to use these C programs anyway through R (i.e. without touching the C programs and fixing the problem in R)? Thanks a lot for any comments. -- Hadassa Brunschwig PhD Student Department of Statistics The Hebrew University of Jerusalem http://www.stat.huji.ac.il

Hello everyone I have data grouped by subjects and i used the trellis plot to show the curve for each subject. I have another vector "a" which gives me the highest points the curves for each subjects can achieve ( the curve is exponential ). Now i want to draw a horizontal line, whose values are saved in "a", on each plot for each subject. Is there any possibility to do that?

Thanks to everyone who replied to my first problem. Here is the second one: Is the function "lme" (Mixed Model) also in a foreign library(shouldnt, as this is a basic statistical function)? I am trying to use lme in R and it replies that it couldnt find the function lme...weird... Thanks for replying!

Hello everyone I've got another question on Trellis plots. I plotted my fitted model with plot(augPred(fitted model)). According to the description of this method, one can use any optional argument which is passed down to the xyplot function for Trellis plots. Additionally to the trivial plot i would like to insert a horizontal line. I tried to do it with the argument panel= function (...)

...ne. I did browse the help and archives but I still haven't understood how to do the following: I run R locally and would like to read in data from a server for which there is a username and password. That is, how do I open a connection to a server with a password?

...G_LIBS=-L/directory_of_tools -l/tools? 2. Does this file need to be located in the same directory as main.c? 3. When I then run the command R CMD SHLIB it does not make use of Makevars. So what do I need to add? 4. Does tools.c need to be a shared object as well? Thanks a lot!

Hi I would like to produce a red shading I figured the easiest way to do that would be to use rgb in the following way: a <- seq(0,0.9,by=0.1) redshade <- rgb(red=1,green=a, blue=a) However, I don't really know how to plot things using hexadecimal colors. I used a function which tries to find the closest color to the rgb shades but it didn't work very well. Any

Hi, I know that with readlines you can start executing a code upon user input. What I would like to do is to have the ability to abort a code based on a new user input. E.g. when the user hits enter the code stops running. That is, I would periodically check for a user input and stop the code when the correct input was entered. Below is an example of a function which would run an endless loop

Hi R-Help! My question: I have lifetime/failure data of machines with different stress levels and i think an weibull/extreme value distribution would fit this data. So I did: model1 <- survreg(Surv(lfailure)~stress,data=steel,dist="extreme") (where lfailure=log(failure)) Now I would like to do a likelihood ratio test to test the hypothesis H0: location parameters of the

Im trying to import data from an excel sheet or a sas file to R...im not succeeding. Apparently the function read.xport for reading a SAS file doesnt exist. What do i have to type in EXACTLY to read from an excel sheet(i guess i would be using read.table?)? Thanks in advance for an answer Dassy

Hello! Several of us here have tried to change the dark grey background color of the graphics device, without success. This grey background color only so far appears for Trellis plots. All other plots are shown with white background color. Is there any way to change this color? Regards Dassy

Hi all, well i know this was probably already posted many times, couldnt find anything about it though. This is a beginner problem. I have a Trellis plot which is very large, i.e. it only shows me the last few panels (after going automatically through the first ones and stopping at the last few). When i scrole with PageUp or Page down it shows me the panels of a graph i did last time but not of

Hi R users! I have a likelihood ratio statistic that depends on a parameter delta and I am trying to get confidence intervals for this delta using the fact that the likelihood ratio statistic is approx. chi-squared distributed. For this I need to maximize the two likelihoods (for the ratio statistic) one of which depends on delta too and I am trying to use the function "mle". But

Dear R-Users! Is there a possibility in R to do analyze longitudinal survey data (repeated measures in a survey)? I know that for longitudinal data I can use lme() to incorporate the correlation structure within individual and I know that there is the package survey for analyzing survey data. How can I combine both? I am trying to calculate design-based estimates. However, if I use svyglm() from

Hi There must have someone already posted this question but I still have not figured how I could do this: Say I have var.1 var.2 var.3 which are large matrices. I would like to do the following loop: for(i in 1:3){ # Pick var.i and do something with it } How can I tell R to do this? Thanks for any comments. Hadassa [[alternative HTML version deleted]]

Hi R-Users! I fitted a negative binomial distribution to my count data using the function glm.nb() and obtained the calculated parameters theta (dispersion) and mu. I would like to simulate values from this negative binomial distribution. Looking at the function rnbinom() I was looking at the relationship between the two possible parametrizations of the negative binomial and found that for this

Hi R-users! I am trying to create a what I call inflated array (maybe there is already some other name for that). It is an array that changes dinamically its dimensions, e.g. the higher the number of third dimensions, the more rows in the array. So for example the array could look like the following: , ,1 1 2 3 4 , , 2 5 6 7 8 9 10 11 12 , , 3 13 14 15 16 17 18 19 20 21 22 23 24 Has

Hi, I was wondering if there is a way to control the strip size in xyplot for example using the strip.default function. Or do I need to redraw the strips by myself? I would like to make the strip slimmer and I have reduced the font size using cex. However, I don't know how to change the size of the strip. Thanks for any tips.
