Dear R user: I am studying the allele data of two populations. the following is the data: a1 a2 a3 a4 a5 a6 a7 a8 a9 a10 a11 a12 a13 a14 a15 a16 a17 pop1 0.0217 0.0000 0.0109 0.0435 0.0435 0.0000 0.0109 0.0543 0.1739 0.0761 0.1413 0.1522 0.1087 0.0870 0.0435 0.0217 0.0109 pop2 0.0213 0.0213 0.0000 0.0000 0.0000 0.0426 0.1702 0.2128 0.1596 0.1809 0.0957 0.0745 0.0106

Hi, I have tried several different line options, but I cannot seem to get the pxe master password option to work? I have basically tried all combinations of: DEFAULT local PROMPT 0 ALLOWOPTIONS 1 TIMEOUT 500 MENU TITLE sometitle MENU MASTER PASSWD somepassword But just can't seem to get the menu to prompt for a password. version I have is pxe 3.31 Thanks for any help

Hi, This report deals with p-values coming from chisq.test using the simulate.p=TRUE option. The issue is numerical accuracy and was brought up in previous bug reports 3486 and 3896. The bug was considered fixed but apparently was only mostly fixed. Just the typical problem of two values that are mathematically equal not ending up numerically equivalent. Consider this series of three 2x2

Dear R user: Now I am studying "matrix population models" and Rmetasim package,but I find it's very difficult to understand this model fully and can't find a good teacher.My question is that:Now I do some research about one marine shrimp: Penaeus chinensis, it's life cycle is one year. after it breed it's offsprings, it will died. This shrimp's life cycle is dicrete

hai, I want to perform a simulation like this仯伜 Suppose that I have one population ,it's size is 500, is composed of x,y and z. The probability of x, y and z is respectively is 0.3, 0.5, 0.2. I wan to simulate a new same size population based ratio of x, y and z, how can I get and assess the number of x, y and z. ? luan Key Laboratory for Sustainable Utilization of Marine Fisheries

I want to th current folder is the specific folder when R start.It is very boring to modify the current directory manually. How can I do it?

Full_Name: Doug Grove Version: 1.7.0 OS: Linux Submission from: (NULL) (209.31.211.56) Hi, Minor mistake in the documentation on the colSums page. In the ARGUMENTS section it states for 'dims' that: For `col*', the sum or mean is over dimensions `dims+1, ...'; for `row*' it is over dimensions `1:dims'. These two are reversed. Thanks, Doug Grove

Hi, It would be great if someone would add write.delim() as an adjunct to write.table(), just as with write.csv(). I store a lot of data in tab-delimited files and can read it in easily with: read.delim("text.txt", as.is=TRUE) and would love to be able to write it out as easily when I create these files. The obvious setting needed for write.delim() is sep = "\t", but in

Full_Name: Doug Grove Version: 2.10.0 10-26-2009 OS: x86_64-unknown-linux-gnu Submission from: (NULL) (140.107.164.65) Hi, Looks like the revisions to help.search didn't get completely finished. When the user specifies the argument 'package' the code doesn't define the variable 'paths' prior to trying to use it, which obviously produces an error. The code dies when

Hi, I'm wondering if anyone can point me to a function that will allow me to do a ranking that treats ties differently than rank() provides for? I'd like a method that will assign to the elements of each tie group the largest rank. An example: For the vector 'v', I'd like the method to return 'rv' v: 1 2 3 3 3 4 5 5 6 7 rv: 1 2 5 5 5 6 8 8 9 10 Thanks,

Hi, I'm trying to understand a behaviour that I have encountered and can't fathom. Here's some code I will use to illustrate the behaviour: # start with some data frame "a" having some named columns a <- data.frame(a=rep(1,3),c=rep(2,3),d=rep(3,3),e=rep(4,3)) # create a subset of the original data frame, but include a # name "b" that is not present in my

Dear list, I am using R 2.1.1 on a Fedora 3 Linux, 32 bit PC. If I compute the aggregated mean and the standard deviation I get standard deviation values for factors where the mean was not computed. It seems to me that this is somehow related to the NA values. But I don't quite understand what is going wrong? Could it be related to the data import already? Some of the imported data got the

Hi, I'm having what I believe are OS problems with my installation of R-1.6.0. The machine I'm using was previously running R-1.4.0. The install seemed fine to me. I didn't note an error messages in 'make' or 'make check'. My problem is that I've been running some memory intesive code, and the code that ran under 1.4.0 but won't run under R.1.6.0 (or under

I have what R seems to consider a very large dataset, a 12MB text file of lat,long,and height values, 130,000 rows to be exact.

Full_Name: Doug Grove Version: R.1.9.1 OS: Linux Submission from: (NULL) (140.107.156.61) I just found that rank() has a 'decreasing' argument that is not documented in its help page. I checked my version of 2.0.0 (original release hence unpatched) and it is not documented there. For curiousity I also went back to version 1.8.1 and checked the function (not the documentation)and at

I tried command as.numeric(Qty) #converting column"Qty" in object "demand" to numeric. However it remains a non-numeric value. What is the best way to convert a column of data to a numeric value in R? What is the best way to convert dates into a numeric format (or some format able to be used in an x,y scatter) while still maintaining its inherent "date" property?

Hi all, I am currently building an application based on R 1.7.1 (+ compiled C/C++ code + MySql + VB). I am building this application to work on 2 different platforms (Windows XP Professional (500mb memory) and Windows NT 4.0 with service pack 6 (1gb memory)). This is a very memory intensive application performing sophisticated operations on "large" matrices (typically 5000x1500

Hi James, Joshua is right, what you're trying to accomplish is quite known in the Java VM world ( http://domino.research.ibm.com/comm/research_people.nsf/pages/dgrove.oopsla01.html ). In order to express the "thunk" code in LLVM you need a full control of how registers are used (because otherwise they would mess up with the arguments). I haven't investigated enough to know if
