Removing a list of Objects
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

Cumulative sum of vector
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 >

sna package: how to import data in linked list format
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?

sna package: how to use dataframes
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

displaying numbers not in scientific notation
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? When I use summary() after using lm() I am getting numbers like 4.485107e-01, when what I want to see is 0.4485.... Thanks, Brian

more function in R?
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. The data I want to look at is larger then my screen size and all I end up seeing is the last fews line of data. Is there a way that I can paginate through the data and the results of my summary functions? thanks, Heidi

clustering coefficient
Hi all, I've been looking for a function that calculates "clustering coefficient" either Newman's or Wattson's. I have found different functions to calculate different "cluster" but I haven't found yet anything for clustering coefficient, it might be under a different name. Any ideas?

Defining functions in separate file...
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
