similar to: A faster way to aggregate?

Hello r-help, I am trying to collapse or aggregate 'some' of a data frame. A very simplified version of my data frame looks like: > tester trip set num sex lfs1 lfs2 1 313 15 5 M 2 3 2 313 15 3 F 1 2 3 313 17 1 M 0 1 4 313 17 2 F 1 1 5 313 17 1 U 1 0 And I want to omit sex from the picture and just get an addition of num,

summary: The function 'by' inconsistently strips class from the data to which it is applied. quick reason: tapply strips class when simplify is set to TRUE (the default) due to the class stripping behaviour of unlist. quick answer: This can be fixed by invoking tapply with simplify=FALSE, or changing tapply to use do.call(c instead of unlist executable example:

Hi all, I have installed centos 5.1 x86_64. 2.6.18-53.1.14.el5 Everything seems to be working fine except that the rtc module is not working. cat /proc/interrupts shows: CPU0 CPU1 0: 129 0 XT-PIC-XT timer 1: 330797 0 XT-PIC-XT i8042 2: 0 0 XT-PIC-XT cascade 3: 4 0

Hi I have come across a problem, with my tdp410 and soekris board (basically pc on a chip amd geode cpu). I am using the box as a firewall/asterisk box. The problem occurs when I drop ppp and I get dead loop dectiotn going, I seem to lose interrupts and get lots of messages in syslog from wctdm24xx saying missed interrupt increasing latency its out lined here

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

Hello I am using a Junghanns QuadBRI ISDN card - the module name is qozap. If I like at my interrupt assignment, qozap is sharing interrupt 10 with libata and uhci_hcd. I think libata is the IDE hard drive module and uhci_hcd is a USB module. linux:~ # modprobe qozap linux:~ # cat /proc/interrupts CPU0 0: 12634579 XT-PIC timer 1: 10 XT-PIC i8042

hi list. after my unsuccessfull experiences with mISDN i tried again to implement a zaphfc based solution. problem is: sound on calls via capi is stuttering/broken and therefore unuseable. my conf: - cel 1300, 256mb ram - avm b1 via capi connected to my outgoing ISDN - acer surf pci via zaphafc and crosslink cable with termination as internal bus - siemens gigaset 3035 as internal phone -

> Subject: Re: [Asterisk-Users] Booting error - Unable to specify channel 2: > No such device I just went through all this as well. The best thing to do IMHO is to try to find a way to manually assign IRQ in the BIOS. Also, and this is what I didn't see at first, some slots SHARE IRQ. Avoid this! If you are not using USB at all, turn it off in BIOS if possible. Tell the BIOS

I have some new PC hardware I'm using with the Intel H67 chipset. I created a bzImage I use for a PXE environment for a recovery mode, installing OS images, etc. The new mobo doesn't have a VGA port but instead DVI. Everytime I unplug the DVI cable it seems to cause "Disabling IRQ #11". After that the PC is basically unusable. The /proc/interrupts shows that hdd, usb, nic,

Hi All, I have an equipment loaded with 4 X100P (numbered 1-4)) and one T400P (numbered 5-8). Everything works fine except that I cannot use one of the FXS ports (number 5). If I configure zapata.conf to recognize it, the whole system voice quality suffers. I've tried already to switch PCI slots, with no results. Below is a snapshot of my /proc/interrupts, maybe this can shed some light on

Hi all, I am using a TDM400P card with 2 FXS and 2 FXO modules. Everything seems nice, but i'm not able to make calls nor to receive any. When I try to make a call, I keep receiven the "all circuits are busy now" message, and when I receive calls, asterisk doesn't seems to care (don't get anything on the CLI) I'm using Asterisk 1.2.17 and Zaptel 1.2.16 from Xorcom's

Excuse my ignorance here, but I am desperately trying to isolate the IRQ for my TE110P card (shown below as t1xxp) Ive gone into my bios and disabled all usb , parallel, serial and some other devices, those that I needed to keep, I have moved off of IRQ 10 and onto IRQ 5, but everytime I boot up, I get usb-uhci and ehci_hcd using IRQ 10 as well as my Digium card. Does anybody know what these are

Thanks for the reply Bill. I am aware of the interrupts problem. To solve it I have already disabled my serial ports freeing up interrupts 3 and 4 and these are allocated to the two cards. This was done 2 months ago and has not solved the problem. Is there any way that something can wake up every now and then and generate these two interrupts? My current /proc/interrupts is as follows:

Dear R users, suppose we have a random walk such as: v_t+1 = v_t + e_t+1 where e_t is a normal IID noise pocess with mean = m and standard deviation = sd and v_t is the fundamental value of a stock. Now suppose I want a trading strategy to be: x_t+1 = c(v_t – p_t) where c is a costant. I know, from the paper where this equations come from (Farmer and Joshi, The price dynamics of common

I have seen this posted around the list a few times, but have never found my exact error or even a solution to this. I was getting this error every few seconds...... After moving the card to a different PCI slot and turning off some devices that are not needed. I was able to get the messages down to about every 10 minutes and the T1 card now is sitting in it's own intterupt. Apr 25 23:49:15

Hi, I have just started to setup and configure my asterisk box and am having trouble with it. I have a dlink nic in the box as well as the digium card. When the nic is in there by itself it works, but when I put the tdm400p in, there seems to be some sort of conflict with the network card. The tdm appears as another type of network card, which I don't think it should, should it? It shows

Dear R users, I'd like to build a simple design matrix in a efficient way. I naively wrote the code below. #### n = 15 k = 3 nbPerGrp = c(5,5,5) xT <- list() for (i in 1:k){ xT[[i]] <- rep(0, k) xT[[i]][i] <- 1 } X <- matrix(nrow = n, ncol = k) #design matrix for (i in 1:nbPerGrp[1]){ X[i,] <- xT[[1]] } for (i in 1:k-1){ for (j
