I want to check it the @session[:user].id exists in an if statement. However, I the user has not yet logged in, the following error occurs. How does one check if this (or any other) cookie exists without getting this error? Thanks!

Dear All, I would like to know, beside writing a function and then apply it to a list, or using a for loop, whether there is a one-line command to do the following. Suppose we have a list, each of whose components are numeric: > a <- vector("list",3) > a[[1]] <-c(1,2) > a[[2]] <-c(3,4) > a[[3]] <- c(5,6) > a [[1]] [1] 1 2 [[2]] [1] 3 4 [[3]] [1] 5 6 Target:

Dear List, I want to let R calculate the time (run-time) it requires to run a self-written simulation function. I tried as follows: it enables me to see the starting and finishing time points. ############################# "sim.result" <- function(nsim, ...){ Starting <- date() ... # calculations # final.result <- ... # Output for display # cat("# of Iterations used

Hello R-Users, I have I simple question that I could not solve: How to extract the elevation and the slope values from a linear model (lm) separately? coef(model.lm) gives both of them.

To Whomever is Interested, I have spent several days searching the web, help files, the R wiki and the archives of this mailing list for a solution to this problem, but nonetheless I apologize in advance if I have missed something obvious. The problem is this; I have a 5-column data frame with about 4.2 million rows, and want to create a new (and hopefully much smaller) data frame that

Where do DEBUG and EH label values originate from ? Where's their allocator ? I am looking at some code in X86CodeEmitter.cpp line 574, where a labels value is extraced from an operand. But dont know where to look in the frontend or middle end to find the LabelID allocator. If some kind person could point me in the right direction. Many thanks in advance, Aaron -------------- next part

I posted the bug at http://sourceforge.net/bugs/?func=detailbug&bug_id=130992&group_id=13478 . Since all my other discs were encoding fine I thought that the wav file may be corrupt/invalid/or something. I opened them with cool edit and "saved as"ed them to my drive. These files encoded fine and the extraced/converted files have the correct md5sum. Is there a program that can

Hi Listers, Surely, I just have a mental block and there is a more elegant way of creating a summary count (other than extracing it from ftable). I''d like to create a new data.frame containing counts of spell by loc ie have three columns showing spell,loc,count. Below the data.frame...

I''m struggling to get Xen to boot on a FC4 Opteron box. I''ve included the tail of the boot log below [1]. I suspect that the problems relates to the software RAID 1 root and boot partitions, and how it relates to the initrd image. The RAID volumes fail to mount. I compiled the Xen snapshot from the 23rd September, and the only change I''ve made is to enable the

Typical log message: Oct 7 11:39:36 hostname dovecot: imap(username): Fatal: master: service(imap): child 14864 killed with signal 11 (core dumped) What triggers the problem: User moving multiple messages to a subfolder via IMAP (from another account, on another server, client: Thunderbird). Moving single messages either does not trigger the problem, or with much lower probability (could not

I am pretty sure it's a flac bug, not a problem with your wav. the -p option is causing the problem. -p drastically increases the runtime and only improves the compression by a tiny bit, which is why it is only turned on in -9. until the bug is fixed it is safer to not use -p (but -V will catch any errors -p causes). --- Kevin Pullin <kpullin@socal.rr.com> wrote: > I posted the bug

Hi, I''m interested in some feedback about a solution for searching multiple related models by columns (as opposed to full-text). A brief example would be three models with typical has_many relations: Hotel (name, company) Room (number, type) Bed (type, age) I have a search form that lists the fields for each model with a text input. Upon submission the search needs to find the results

Hi, I'm trying to make a triple-boot recovery CD containing Linux System Rescue, XP Recovery Console, and DOS/WinME for GHOST etc. I can compile the ISO fine, and the System Rescue stuff works fine too, but when I try to boot the XP image isolinux says "Image checksum failure... sorry" and dies.

Hi, I''ve started learning about EventMachine right now and have some basic doubts. Hope you could clarify them. I''m developing a SIP server. For now I''ve started it from scratch but I expect to migrate it to EventMachine. SIP is a very complex protocol. For example: if I use a SIP proxy in front of my server then all the data will arrive to my server using the same TCP
