Hi, The following function works, but is there a neater way to write it? f = function(x,...) { # return a character vector of the arguments passed in after 'x' gsub(" ","",unlist(strsplit(deparse(substitute(list(...))),"[(,)]")))[-1] } > f(x,a,b,c*d) [1] "a" "b" "c*d" > Thanks. [[alternative HTML

Hello, I have a dataframe which I read from a file: df <- readtable(myFile); The dataframe has 4 columns: "model", "count", "value" and "date" where "model" and "date" are made of charactors and "count" and "value" are numbers. An example is like: model count value date A 4 20.8

Hi folks, I'm having a spot of bother with tempdir(). If I set the environment variable TMPDIR in my shell prior to invoking R it works as expected: > Sys.getenv("TMPDIR") TMPDIR "/eurotempest/tmp/R" > tempdir() [1] "/eurotempest/tmp/R/Rtmp0xY4XD" However if I don't set it prior to entry, but attempt to set it from within

Hi I had observed the following problem in R (also C, Matlab, and Python). sprintf('%1.2g\n', 3.15) give 3.1 instead of 3.2 whereas an input of 3.75 gives 3.8. Java's System.out.printf is ok though. > round(3.75,1) [1] 3.8 > round(3.15,1) [1] 3.1 Similar outcome with sprintf in R. However, the right answer should be 3.2 Regards Teckpor [[alternative HTML version

Hi, In the example below why is d 10 times bigger than m, according to object.size ? It also takes around 10 times as long to create, which fits with object.size() being truthful. gcinfo(TRUE) also indicates a great deal more garbage collector activity caused by data.frame() than matrix(). $ R --vanilla .... > nr = 1000000 > system.time(m<<-matrix(integer(1), nrow=nr, ncol=2)) [1]

Dear List: When I click on the link to download a reference manual for a package on cran, I get an error message that the file is damaged and could not be repaired. I randomly chose various packages and the same error message appears. Are the links actually broken? I have also restarted my machine and closed and re-opened acrobat. I am using Windows XP, Acrobat Professional 6.0.0.5, and

Dear R-helpers Apologies for the basic question, but I just got stuck: I would like to write values from a vector into array cells with the same names > count[1:10] 10010 10014 10015 10017 10030 10080 10100 10230 10250 10280 0 0 0 0 0 1 1 0 2 0 >data[1:10,,1] [,1] [,2] [,3] [,4] [,5] 10010 NA NA NA NA NA 10014 NA NA NA

Dear R users, I want to generate two random variables (X1, X2) from uniform distribution (-0.5, 0.5) with a specified correlation coefficient r. Does anyone know how to do it in R? Many thanks! Menghui

Hi Folks! I'm reading in some data from a .csv file that has a date column. How do I use colClasses to get read.csv to recognize the date column? The documentation on this seems to be nil - And yes, I've read help and R Data Import/Export and can't figure out what the colClasses syntax is. Thanks, john [[alternative HTML version deleted]]

I am wondering if someone would have any suggestion about my issue? I have the following code: wgts<-aggregate(subset(lendata,select=c(Length)),list(lendata$Cruise,len data$Station,lendata$Region,lendata$Total),mean) wgts<-wgts[order(wgts$Group.3,wgts$Group.1,wgts$Group.1),] names(wgts)<-c("Cruise","Station","Region","Total","MLen")

Hi, Please see below for post on r-help regarding data.frame() and the possibility of dropping rownames, for space and time reasons. I've made some changes, attached, and it seems to be working well. I see the expected space (90% saved) and time (10 times faster) savings. There are no doubt some bugs, and needs more work and testing, but I thought I would post first at this stage. Could some

When I do t.test on two distributions (see example below), it outputs numerous data about the t.test. What I'd like to do is individually capture some of this data and assign it to other variables. However, I am unable to find anything in the help section. In the example below, the t value is -4.0441 and the p-value is 0.006771 How can I assign these values to two variables, let's

Hi, I am trying to convert the following NLMIXED code to NLME, but am running into problems concerning 'Singularity in backsolve'. As I am new to R/S-Plus, I thought I may be missing something in the NLME code.

Is there any reason why 'attach' is not generic in R? I notice that it is in another system, for example, and I can see some applications if it were so in R. Bill Venables. Bill Venables, CMIS, CSIRO Laboratories, PO Box 120, Cleveland, Qld. 4163 AUSTRALIA

I have a dataframe with 700,000 rows and 2 vectors (columns): ?group? and ?score?. I wish to calculate a third vector of length 700000: the average score by group. Even though the avarge value will repeat, I wish to return the average for that particular group for each row. (I know I can do this by calculating each group?s average and then using the merge command, but as my calculations get

Dear R-help, I am trying to build R-2.2.0-patched (2005-11-07 r36217) on the head node of a Scyld cluster (dual Opteron 250s) using PGI compilers (v6.0). I used the flags suggested by Jennifer Lai on R-devel (taken from R-admin, except that I had to add -L/usr/X11R6/lib64 to LDFLAGS). The build went fine, but make check-all failed when running tests/Examples/graphics-Ex.R, at: > plot(1:2,

Full_Name: Uffe H?gsbro Thygesen Version: 2.2.0 OS: linux Submission from: (NULL) (130.226.135.250) Hello all. pbinom(q=0,size=0,prob=0.5) returns the value NaN. I had expected the result 1. In fact any value for q seems to give an NaN. Note that dbinom(x=0,size=0,prob=0.5) returns the value 1. Cheers, Uffe

We have R 2.2.1 installed on a Linux cluster that seems to have problems loading either of our shared object libraries for packages. This seems to be happening on both local and global versions of packages that we install. However, we have only noticed this problem in the past 3 months on this R installation, whereas some users had success before then. It could be that something on our system

All, When I take a subset of a factor the reduced factor still maintains all the original levels of the factor when say forming the key in a plot. The data is correct, but the variable still "remembers" the original levels. See below for reproducible code. Does anyone know how to fix this? cheers, dave fact = as.factor(c(rep("A", 3),rep("B", 3), rep("C",
