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.

This is was something like a request for your comments, thoughts on the topic... Many of you will know that the "..." (aka \dots) argument is very useful for passing ``further graphical parameters'', but can be a pain when itself is passed to too many plotting functions inside your own function. An artificial example being myplot <- function(x,y, ...) { plot(0:1, 0:1,

Dear R-users, I am translating a S script into R and having some troubles with the match function. This function appears to work with vector and data.frame in S, but not in R, e.g.: a <- rep((1:4), each = 10) b <- rep((1:10), times = 4) mydf <- data.frame(a,b) myarg <- mydf[1,] match(myarg, mydf) # S returns 1 but R returns NA NA I guess one could use match(interaction(myarg),

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 =

I am trying to have llvm and clang on a centOS 5 without root permissions. I tried to do it downloading llvm and clang src packages and trying the ususal configure, make and make install steps as such: wget http://llvm.org/releases/3.3/llvm-3.3.src.tar.gz wget http://llvm.org/releases/3.3/cfe-3.3.src.tar.gz tar xzf llvm-3.3.src.tar.gz && cd llvm-3.3.src/tools/ && tar xzf

Hi, all How to format and join strings ? For example, like following short python examples. ********* name1 = 'sample-plot' filename = '%s.png' % name1 inputdir = '/path/to/dir' os.path.join(inputdir, filename) ********** Best, Hyunchul Kim [[alternative HTML version deleted]]

Dear List, just out of pure curiosity: is it possible to define a function via 'substitute()' such that the function's formal arguments are specified by a "wildcard" that is substituted when the expression is evaluated? Simple example: x.args <- formals("data.frame") x.body <- expression( out <- myArg + 100, return(out) ) expr <-

Using R 2.4, the following fails: setClass("testc", representation(a="ANY")) makeC <- function(myarg) new("testc", a=myarg) makeC() -> Error in initialize(value, ...) : argument "myarg" is missing, with no default On the other hand, this is OK: f <- function(a) g(b=a) g <- function(b) if(missing(b)) "missing" else "valid

Could someone please apply this patch to the Win32 support so that Morten and Jeff can handle the recent changes? I can't do it because I"m on the road with only email access.

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.

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

Frequently we have a print method, say print.myclass, that has a variety of arguments. If in the .Rd file I say \usage{ \method{print}{myclass}(x, myarg) } I get a warning when running R CMD chk: * checking generic/method consistency ... WARNING print: function(x, ...) print.myclass: function(x, myarg) What is the proper way to handle this? Thanks -- Frank E Harrell Jr

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 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.

Below is an example of output that changed as a result of r64970. I did not see any NEWS item suggesting this change is expected. Note that the example is contrived and I don't have a use case for it. I stumbled across it when playing with recent changes in R relating to duplication. Does the example use undefined syntax? ----- fn1 <- function(mylist) { fn1a <- function()

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]

Hey folks, I have a problem with the definition of a variable of type slist in CFEngine on # uname -a ; cat /etc/redhat-release Linux policyhub.example.com 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux CentOS Linux release 7.4.1708 (Core) I'm not sure if its valid to ask CFEngine questions on this mailing list, but as far as I'm running on

Dear R-core Team, As Thomas Lumley pointed out in one of his e-mails one can use commandArgs() to get a copy of the command line arguments supplied when R session was invoked and then use grep to extract parameters of interest. His solution works very well if the custom options are passed by names, e.g. --my-option=value, but what if one wants to pass parameters by their positions. Then it's
