...c.tar.gz && cd llvm-3.3.src/tools/ && tar xzf ../../cfe-3.3.src.tar.gz I tried with a newer version of gcc compiled for this 64bit CentOS system, because the older version wouldn't work (see below). When I try it with the newer version, I get this: export LD_LIBRARY_PATH=/home/avilella/src/gcc/gcc-4.7.2/lib64:/home/avilella/src/gcc/gcc-4.7.2/lib export CC=/home/avilella/src/gcc/gcc-4.7.2/bin/gcc export CXX=/home/avilella/src/gcc/gcc-4.7.2/bin/g++ export PATH=/home/avilella/src/python/python-2.7.3/bin:$PATH cd ~/src/llvm/latest/llvm-3.3.src ./configure --prefix=/home/avilella/src/...

Hi all, I would like to know how can I sort the cols of a matrix by the sum of their elements. a <- matrix(as.integer(rnorm(25,4,2)),10,5) colnames(a) = c("alfa","bravo","charlie","delta","echo") I guess I should use colSums, and then rearrange the matrix somehow according to the result. My idea is to display a "sorted" barplot:

Hi all, I would like to do a barplot of a dataframe like this one: alfa beta gamma delta qwert 56.5 58.5 56.5 58.5 asdfg 73.0 73.0 43.0 73.0 zxcvb 63.0 63.0 43.0 63.0 yuiop 63.0 63.0 43.0 63.0 with the labels of the rows and columns. I would like to have something that works for dataframes with varying dimensions, and so far I haven't found any way to do it.

Hi all, I'm trying to process all files with a certain extension "*.ext" in a directory like this: > R --slave --args /my/dir < dir_plot.r where I then I want to do something like: myarg <- commandArgs() inputdir <- myarg[length(myarg)] print(inputdir) "for file with extension "*.ext in inputdir" do data = process.data(file) outfile =

Hi all, I am trying to filter the element of a df that start with "TF", like this: alfa = c(123221,"TF13124",41243,"TF1234",32414,"TF13124","TF14333",2134123,"TF1234") beta =

Hi, (I googled for this answer but didn't find anything) I am using density plot and I want to trim the ends of the line. eg: i = rnorm(100,100,2) j = subset(i,i<102 & i>98) summary(j) plot(density(j)) I only want the line to go from 98 to 102. How can I limit the line (and the axis) to the values I specify? Cheers, Albert.

Hi, I've got a dataframe like this: df = data.frame(a=rnorm(100,1),b=rnorm(100,10),c=rnorm(100,100),d=rnorm(100,-100)) and I want to calculate sd1 for (a,b,c) for each entry, and sd2 for (b,c,d) for each entry. I don't seem to find the answer using aggregate or apply, How can I do this? Thanks in advance, Cheers, Albert.

Hi, I've got a list of ~20000 elements that look like this: [1] "A00096:A00096:A00096:A00096:A02178:A02178:A07776" [2] "A00046:A00076:A01101:A04146:A05671:A07169" [3] "A00038:A00932:A02185:A02370:A02818:A02818:A02818:A02818:A04732:A07142:A07142" [4] "A00096:A01352:A01352:A02023:A05001:A05001:A07776" [5]

Hi, I've got a csv file with scores like this: 40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,32,38,40,20,40,26,40,30,40,5,5,13,12,40,40,3,33,29,23,2,24,9,15,4,21,16,5,26,8,8,18 40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,40,32,40,40,30,40,40,37,34,40,36,13,40,13,40,5,40,8,29,5,15,34,5,22,14,20

Hi all, I'm trying to superimpose a rchisq density line over a histogram with something like: hist(alnlength) lines(density(rchisq(length(alnlength), 4)),col="red") But the rchisq line won't appear anywhere, Anyone knows what I am missing here? Thanks in advance, Albert.

I want to take the first row of each unique ID value from a data frame. For instance > ddTable <- data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry")) I want a dataset that is Id Name 1 Paul 2 Bob > unique(ddTable) Will give me all 4 rows, and > unique(ddTable$Id) Will give me c(1,2), but not accompanied by the name column.

Hi all, I would like to factorize the entries in a dataframe given some groupings. E.g: mydf = data.frame( a = rnorm(100,10), b = rnorm(100,10), c = rgamma(100, 1, scale=1)) group = hist(mydf$c, breaks="FD") group$breaks The idea is to create a factor "mydf$d" with levels corresponding to the ranges in group$breaks. There must be an easy way to do this that I

Hi all, I would like to ask if it is possible to use bubbleplot for a 20x20 matrix, instead of a dataframe with factors in columns. The idea would be to get a tabular representation with bubbles like in Rnews_2006_2 article, which look very nice. Thanks in advance, Albert.

Hi, I've been investigating the ape package for a while, and I was wondering if it is possible to: - display the names of the internal nodes (from a newick tree) - plot a pie-chart on top of each of the internal branches in a phylogram plot Thanks in advance, Cheers, Albert.

Hi all, Has anything changed since this email that will make OpenCL support in nouveau easier? I would like to compile some information about the different steps needed to have OpenCL support for Nouveau (and the ATI open-source drivers for that matters) so that people interested in this issue can have a starting document to read. Cheers, Albert. > Kernel allows you to create the relevant

Hi, How can I use a substring match as a condition in a subset command? Sth like this: subset(input, field1=="blah1" & field2=="blah2") # but now with substring match in field2 subset(input, field1=="blah1" & field3 *substringmatch* "blah3") I've tried with gsub, but it won't work: subset(input, field1=="blah1" &
