Hi .. another newbie question .. is it possible to "lock" a function (or indeed any object), making it read-only until "unlocked"? For example, should I inadvertently (or through sheer stupidity <g> ) override the definition of t > t function (x) UseMethod("t") with > t <- function(x){min(x)} R raises no objection and uses this new version happily

The user section of one of my smb.conf files looks like this yet when I bring up XP (a guest under VirtualBox) on my system, all linux dot files are visible. Am I missing somethng? [fred] comment = Alan's service path = /home/fred writeable = yes valid users = fred admin users = fred browseable = yes case sensitive = no printing = bsd #print command =

Hey all, I understand that a def self.abc, for example, is a class method, which allows you to call its contents by just referencing model.abc (rather than model.new.abc). However, what is its role when located in a method inside a model like in the code below. Also in the code below, you see :: located in the method. Isn''t that used for modules and namespaces? If so, why is it located

Hi, I''m trying out the example (more or less) straight from the tutorial: doc = Document.new doc << Field.new("id", "a", Field::Store::NO, Field::Index::UNTOKENIZED) doc << Field.new("title", "b", Field::Store::YES, Field::Index::UNTOKENIZED) doc << Field.new("data", "c",

Hi all, since a few weeks I'm experimenting with some "IMAP forward boxes", but I didn't find a satisfactory solution yet. Target function is a directory structure like following in a shared mailbox: /intern/users/fred /intern/users/ted /intern/users/alice The idea is, that a mail, moved to the directory "/intern/users/fred" via IMAP-client will be forwarded to

Hi everyone, I have noticed that is.vector returns FALSE if I attach attributes: > x <- c(a = 1, b = 2) > attributes(x) $names [1] "a" "b" > is.vector(x) [1] TRUE > attr(x, "fred") <- "happy" > attributes(x) $names [1] "a" "b" $fred [1] "happy" > is.vector(x) [1] FALSE This seems inconsistent to me,

Hello everybody, Two - I hope Simple questions about working with workspaces. Is there a way to force R to start in "clean" workspace / avoid "previously saved workspace restored"? When I load workspace"2" working in workspace"1" everything from "1" is written into "2" is there a way to avoid it? Best regards, Daniel Rabczenko

Hi, I have a new install of c7 with the gnome desktop. I run it with 12 workspaces. Normally I create the shortcuts so that ctrl+f1 maps to workspace 1 ctrl+f2 maps to f2, etc. When I goto applications -> settings -> keyboard -> shortcuts -> navigation, I only have the ability to define "Switch to workspace" 1 through 4. There does not appear to be a way to map keyboard

Compiz is showing only 4 workspaces when I log in. If I go in to the compiz settings manager -> general -> general options -> desktop size it says 8 in Horizontal Virtual size. I can get it to work right if I move Vertical Virtual size to the right then back to 1. How do I get it to stay showing 8? Thanks, -wes

I was editing a file in gvim when I inadvertently pressed some key combination that caused the vim window to disappear from the desktop. I looked in ps and found that it was still running. Checking the tool bar at the bottom of my display I noticed that a large rectangle now occupied the second of four boxes on the extreme right hand side. Clicking on that box brought back the gvim instance but

How about this one? If I set a variable in a data.frame with a two- part name including a dot (say y.pair), and if the variable with the name of the first part (y) doesn't but I ask for it's value I get the value of the two-part name. Ie set fred$x.pair and print the value of fred$x it gives me the value I set to fred$x.pair. Weird and somewhat disturbing! Maybe an example makes it

I've seen a number of issues with the loading of workspaces discussed previously, but here's another one... I simply can't load any saved workspace at all... Here's an example, starting with an empty workspace and creating a single variable "a". > a<-1:5 > save.image("a.Rdata") > rm(a) > load("a.Rdata") Error in function ()  : unused

Hi everyone, I think the following error is slightly odd: > fred <- new.env() > happy <- function() fred > happy() <environment: 0x8a425b8> > attr(happy(), "foo") <- 1:10 Error: invalid (NULL) left side of assignment But naturally this works > attr(fred, "foo") <- 1:10 > fred <environment: 0x8a425b8> attr(,"foo") [1] 1

Hello, Are there any recipe to handle serialization / deserialization of external pointers. I'm thinking about something similar in spirit to the way we handle finalization of external pointers. Currently, if we create an external pointer, save the session, quit R, then load the session, we get a null pointer. One way I'm thinking of is to have an environment in the

Can anyone explain what I'm doing wrong here: > fred <- data.frame() > class(fred) [1] "data.frame" > test.fn <- function(x,class=class(x)) {class} > test.fn(fred) Error in test.fn(fred) : promise already under evaluation: recursive default argument reference or earlier problems?

When I try to drag an app between workspaces, it doesn't move. I'm using compiz. When I put an arrow over an app in the workspace panel viewer (whatever that is called), it says click to start dragging, but no go. Any ideas? Thanks, -wes

Hi, R-listers I tried to plot several graphs in a sigle x-y coordinate settings, like the following: |(y) s | ****** s | ***** s | sssssssssssssssssss |_______________________________(x) where "*" and "s" denote two diffrent plots. However, when I used plot(data1); % data1 is the data points of "*"

I'm using Ubuntu 10.04 with five workspaces set up in GNOME. I assume it's using compiz (I didn't tell it not to), which I know can interact problematically with Wine. I use Notes 7.03 for Windows quite happily in Wine at work. (I know there's a Linux client, but the installer seems very hard to get hold of casually.) As long as I use only one workspace. If I open it in one
