Hi, I have a simple beginner's question on removing a list of objects. Say I have objects C243.Daily1, C243.Daily2...C243.Daily5 in my workspace. I'd like to remove these without using rm five times. So I write. > a <- list(paste("C243.Daily",sep="",1:5)) > rm(a) Obviously this wouldn't work, as it would only remove the object a. But is there any way

Hi, I'd like to execute simple commands and functions in R through a website, is there any service like this somewhere?

Hi, folks: I need to generate all 0-1 sequences with given length,say,n=3, the ideal result would be the following matrix: 0 0 0 0 0 1 0 1 0 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1 Any help would be appreciated. -- View this message in context: http://www.nabble.com/How-to-generate-all-permutation-of-0-1-sequences-in-R--tf4704377.html#a13446919 Sent from the R help mailing list archive at Nabble.com.

Hi, Maybe I have not been looking in the right spot, but, I have not been able to fine a command to automatically calculate the running cumulative sum of a vector. Is there such a command? Example of current code: > eig$values [1] 678.365651 6.769697 2.853783 > prop<-eig$values/sum(eig$values) > prop [1] 0.986012163 0.009839832 0.004148005 >

Is there any function in R like is.not.found(x, y) meaning if you can't find object x, then use object y?? Mikkel Grum

Hello, I have several "linked list" format network files that I'd like to read into R. Although I found a function to export files in .dl format, I could not find a function to read files in such format. Is there any quick way to read linked-list format files into R? Thank you very much. Jorge Colazo PhD Student University of Western Ontario [[alternative HTML version deleted]]

Hi, I an new to R and I realize this may be a silly question, but I searched the manuals and the list archives and can't find the answer. When I read data from R I get a dataframe with labels for rows and columns. SNA however asks for pure adjacency matrices, and if I try to use the dataframe gives an error message. What should do? Thanks a lot Jorge A. Colazo U. of Western Ontario

Dear all, I am using a program that generates similarity matrices in the following non-redundant pairwise format. a b 0.4 a c 0.5 a d 0.3 b c 0.9 b d 0.6 c d 0.2 matrix(c('a','a','a','b','b','c','b','c','d','c','d','d',.4,.5,.3,.9,.6,.2),byrow=F,nrow=6) I would like to convert this to a

Sorry for asking such a simple question, but I couldn't find the answer through a search... How can I get R to show me the values of estimates *not* in scientific notation?

I'm an R newbie and I just have a simple question. I'm using interactive R on a linux box and I'm trying to find out if there's a more or a less function.

Is there a way that I can paginate through the data and the results of my summary functions? thanks, Heidi

Hello, is it possible to define functions in a file, say, myfunctions.R, and import them into R -- into the top-level namespace? I've seen in the documentation that you can create packages, but this seems very heavy-duty, as it requires me to createa subdirectory, and various other files. TIA Martin
