Dear R users. I am little lost and i need your help. I have such data. DATE i Symptomes t 1 2009-04-24 Mexique 0 14358 2 2009-04-24 usa 0 14358 3 2009-04-26 Mexique 18 14360 4 2009-04-26 usa 100 14360 5 2009-04-27 Canada 6 14361 6 2009-04-27

Hello, I have some data in a data.frame where for each of a number of subjects, I have scores for all of a number of symptoms. Subjects are subdivided in a number of groups, which have unequal sizes. I'd like to plot between-group differences in the scores on the various symptoms. Ideally, that would be in a form as would be produced by > bwplot( Score~Symptom ) but I'm not sure one can say anything about t...

I am using many-to-many using :through since I need to store additional information in the join table. I am doing this and it seems to work. I want to verify that this is the best way to do this.

...the phone locks up. "Locks up" means that the bottom part of the screen ("Your current options" and the redial/newcall/cfwdall keys) disappears, and all keys on the keypad are non-functional except for the *-6-settings reboot keys.

Hello, I've been trying to answer a problem I have had for some months now and came across multivariate multilevel modeling. I know MPLUS and SPSS quite well but these programs could not solve this specific difficulty. My problem: 9 correlated dependent variables (medical symptoms; categorical, 0-3), 5 measurement points, 10 time-varying covariates (life events; dichotomous, 0-1), N ~ 900. Up to 35% missing values on some variables, especially at later measurement points. My exploratory question is whether there is an interaction effect between life events and symptoms - an...

Dear latexRs, I tried to make a latex printout of a simple categorial ftable. It should look like the output of print.ftable. Any ideas how to get the syntax of summary.formula right. Or some alternative? As far I see, xtable does not have method for ftable. Dieter library(Hmisc) n=500 sex <- factor(sample(c("m","f"), n, rep=TRUE)) treatment <-

Hi all, After I converted my Linux desktop from Mandriva 2008.1 with Samba 3.0.28a to Ubuntu 9.04 with Samba 3.3.2, my Windows 98 box could no longer connect to my Linux desktop via Samba. The symptom was that Windows kept asking for the IPC$ password. Linux clients have no problem with the Ubuntu Samba server. My machine is called "mydesk", and on every Linux box in the house, the

Restarted bind9 tho..nothing happend. What kind of process could do this? As a last chance I restarted the server..that helped. Regards, Robert

For some strange reason, a samba setup which was previously working has suddenly stopped working, and I can't figure out why. The symptoms is that attempts to write some files onto a samba filesystem take a long time, and then error out with the error message (in Windows dialog box): "Cannot create or replace <filename>: The specified network resource or device is no longer available." On the Samba server side, the a...

Hi Ben, Dave, Since 3.5-rc0, I have been experiencing occasional screen corruption on my MacBookAir3,1, using a GeForce 320M (nv50, 0xaf). The X driver version is xf86-video-nouvea-1.0.1-1 (arch). I do not know what the root problem is, but I have been able to isolate the symptoms to the usage of nva3_copy.c. The patch below is the least intrusive way I could find which kills the symptoms. Hopefully this will sched some light on the true problem, such that a fix can be found for 3.5. Thanks, Henrik The nva3 copy engine exhibits random memory corruption in at least one cas...

...f leftover semaphores created by NRPE (owned by the nagios user); I deleted them but nothing has changed, so they were a symptom, not the cause. I'm still kind of hoping it's a software issue, but chances are slim. OTOH, I can't imagine any hardware problem that would exhibit these symptoms. Any idea what to test? -- Florin Andrei http://florin.myip.org/

This is a bit off topic, because I 'think' it isn't an Asterisk problem. However I'm not sure and anyhow I'm hoping someone may recognize the symptom. We moved offices a month ago. Our trusty SNOM190s (all between 3 and 5 years old) were packed up for the move, then unpacked a couple of weeks later. On unpacking them and connecting them to the new network, several of

Hi, Using arima on data that are in a data frame, especially when adding xreg, would be much easier if the arima function contained 1) a "data=" argument 2) the possibility to include the covariate(s) in a formula style. Ideally the call could be something like > arima(symptome, order=c(1,0,0), xreg=~trait01*mesure0, data=anxiete) ( or arima(symptome~trait01*mesure0,

...I just ran the following logit regression. But can anyone tell me how to calculate how much more likely males (Male=1) could show such symptom than females(Male=0)? I know it must be simple to get once I have the coefficients, but I just don't recall. Thank you very much! Call: glm(formula = Symptoms ~ 1 + Male, family = binomial(link = logit), data = HA) Deviance Residuals: Min 1Q Median 3Q Max -6.038e+03 -2.067e-06 0.000e+00 0.000e+00 6.720e+03 Coefficients: Estimate Std.
