Could any one tell me there is a search function for R-help Archives? Thanks

Hi, I get an error saying " Cannot allocate vector of size 71289kb". So I tried to increase memory by memory.limit(size=3000000000), I also tried other numbers. Each time I get the message NULL and then I still get the same error as above. I'm using Windows 2000. The system has 1G RAM, and 1.6GHz processor. I was only running R, and was trying to do use a BioConductor package. I

Dear all, the default plotting method for hclust trees looks just fine for few objects like in the example dataset. But when it comes to many objects (some 1000 - I'm trying to visualize clustered microarray data) it renders a tree, that one cannot inspect, because of overlapping text and lines. My question is, is there a way or a plotting parameter for plotting a tree which is wide enough

Hi all, The function heatmap uses the functions dist and hclust with default parameters. How to change these parameters? For example, i want to use the ward criterion for hierarchical clustering with binary distance. Best regards, Olivier.

I am trying to build hdf5 for ms-windows. I downloaded the hdf5_1.4.7.tar.gz, gunzipped it and got a tar file. I extracted everything into a directory tree called hdf5. I also found a Makevars.win and libhdf5.def in the R help archives from March 2002. I put those two in hdf5 as well. I issued the command Rcmd build --binary hdf5 but got this message complaining it can''t find

Can anyone suggest a good way to handle multiple versions of R and also other tools like gcc and perl (in Unix). I have been using soft links from my personal bin to the version I want to use, but this has some drawbacks. With this scheme it is difficult to run different versions of R in different windows, and use of gcc appears to be complicated in several respects when I try to change among

Hi everyone another documented feature that was a bit unexpected for me: R> x <- 19 R> f <- function(t){t+x} R> f(100) [1] 119 --as expected: x is visible from within f() ..but... R> g <- function(a){x <- 1e99 ; return(f(a))} R> g(4) [1] 23 --the "x" that is visible from within g() is just 19, which is not the one I expected it to find. R> rm(x)

Hi, I have a program written in R which is good on the version 1.2, but for the fallowing versions of R, an error always is at the same place. That is at the level of the fallowing line: Sur<- getInitial(res2[m:M,2]~SSasymp(res2[m:M,1],Asymp,resp0,lrc),data=res2) Error in eval(expr,envir,enclos):numeric envir arg not of length one I don't know at all this langage for the instant.

Dear R-users, I'm trying to extract the exact location of the maximum value in a vector or a matrix, meaning I want not only the maximum itself but also at which position (e.g row 6, column 12) it is located. I appreciate any suggestions. Thanks, Patrick -------------- next part -------------- A non-text attachment was scrubbed... Name: patrick.vcf Type: text/x-vcard Size: 339 bytes Desc:

Hello, I need help, after hours trying to do it myself, to do the following: I have an object, named, say, F1 from a class "fichier" that I buildt. this F1 has a slot named datas ,which is a vector, so I can access to : F1 at datas[1], F1 at datas[2], ... Now I have a string s="F1 at datas[1]" and need to retreive the real content of F1 at datas[1] using s.

I'm using R in a student lab with machines running win XP. $RHOME is not writable by the students. How do I set this up so that they can install packages?

Hi! I'm having a small problem with an assignment I have to do. We want to do an anova on some values, given for four different types of medicine. The different sample numbers are not identical (eg for molecule A we have 8 values, for B we have 14, etc.). What would the most elegant way of getting this info into R to do an lm be? I usually try to use data.frames but R categorically

> data(iris) # iris3 is first 3 rows of iris > iris3 <- iris[1:3,] # z compares row 1 to each row of iris3 and is correctly computed > z <- c(F,F,F) > for(i in seq(z)) z[i] <- identical(iris3[1,],iris3[i,]) > z [1] TRUE FALSE FALSE # this should do the same but is incorrect > apply(iris3,1,function(x)identical(x,iris3[1,])) 1 2 3 FALSE FALSE FALSE

Hello, R users. In C (or C++) language, a function can be used as an argument of another function as follows: // function used as an argument void foo(int x) { ... } // function using a function as an argument void bar(void (*func)(int ), int arg1, int arg2) { .... } // The function 'bar' will be called as follows int main() { .... bar(foo, arg4foo, other_arg);

I have a quick question which is very simple but I seem to have a mental block! I'm using the pchisq function to specify a Chi Squared distribution with 9 df which I'm then going to use in the Kolmogorov-Smirnov Test to test some simulated values. so simply: pchisq(q, df=9) I know that q is the vector of quantiles but could anybody tell me what exactly this vector needs to contain?

Hi, This is a very trivial question, and I do not know why I cannot remember the answer at all! How does one get the entire system information (which OS, R version....etc) using an R command?

Is there any way to process the "vignette" documantation files? I have been looking at the bioconductor packages and most of them have *.Rnw files in doc directories. They look like regular TeX but have sections showing R code that seem to choke TeX.

Dear all, I had to extracts/set elements from/in a matrix. Let say I have two vectors dim1 and dim2 of indices in the respective two dimensions of a matrix: I want to extract all the corresponding elements. I the case of a nxn matrix, dim1 <- 1:n and dim2 <- 1:n would extract the diagonal. I know one way would be to use the functions 'row' and 'col', but the matrixes I

Hi all, Appologies for the rather basic IO question but I am rather new to R... Migrated from IDL/Matlab recently. I have a rather simple Fortran control file (sigh...) that I am trying to parse and read using R. My problem is that the file's format is somewhat flexible. Imagine: --- 1> 39 1901 2> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 3> 22 24 26 28 30 32 34 36

Hello, I need to read a vector containing names of different variables from a text file (a unique column). Among them one is called "T". When I use the function read.table with default arguments and when I call the element of the data frame corresponding to name of this variable it returns me the logical value "TRUE" whereas I was expected it to return the character
