Hallo, I build a list by the following way: Lst = list(name="Fred", wife="Mary", no.children=3, cild.ages=c(4,7,9)) I know how I can extract the information one by one. But now I want to add a new entry which looks like name="Barney", wife="Liz", no.children=2, cild.ages=c(3,5) How can I add this information to Lst without overwriting the first entry?

Hello Everyone, I am relatively new to linux and Samba and I am having some difficulties setting Samba up as a Primary Domain Controller. Ihave read the Pdf document called "Using Samba as a PDC" by developrWorks and I have read most of the Howto documents relating to Samba. When I try to connect to my samba server with Win98se I get the message "no Domain server was able to

R-Helpers, I'm sorry to have to ask this -- I've not used R very much in the last 8 or 10 months, and I've gotten rusty. I have the following (ff2 is a subset of a much, much larger dataset): > ff2 hostName user sys idle obsTime 10142 fred 0.4 0.5 98.0 2007-11-01 02:02:18 16886 barney 0.5 0.2 94.6 2007-10-25 19:12:12 8795 fred 0.0 0.1 99.8

R-help: I have a variable ("ID_list") containing about 1800 unique numbers, and a 143066x29 data frame. One of the columns ("ID") in my data frame contains a list of ids, many of which appear more than once. I'd like to find the subset of my data frame for which "ID" matches one of the numbers in "ID_list." I'm pretty sure I could write a function

Updated my Athlon-xp 6-stable system last night, got an em watchdog timeout for the first time a few hours later, during a fairly high-traffic period. System is UP but does have device apic in the config. Any chance this is the recent race condition? Workaround? ifconfig em0 down, ifconfig em0 up seemed to cure it, at least for the moment. Thanks, Barney Wolff -- Barney Wolff I never

Hi. I''ve installed ruby, gems, rails into a user directory according to the installation instructions (for linux). I haven''t setup any path information nor setup any symlinks or any compilation options. When I try rails, I find that the system accesses controllers but that the corresponding views are not displayed. I wonder if there is something that I forgot to configure

I thought I had things figured out, but guess not. I have multi-user Quickbooks databases that functioned fine on a Novell server but are behaving badly on a Samba share. I have created a separate share for the Quickbook databases, users are running Win XP Pro, latest patches, and the Quickbooks application installed on the desktop. It is a multiuser version. Server is RedHat ES 3, Samba

The smb service is not starting automatically. I can type service smb start at the prompt and it loads, and I can then connect, but its not loading automatically as it used to. Can someone point me in the right direction as what file I need to change to make it load at startup. Thanks! Liz

I guess I understand it now (although it is surprising to me). The following is a valid model formula fred ~ wilma + offset(barney) that sets the model offset to barney. Given that this works, it would seem that one could remove the offset = argument from the glm call (and document the offset feature somewhere). Too bad that one can't set weights the same way. The anova bug when offsets

Hi! I'm using a large panel data, and now I have faced some difficulties with my analysis. The predictors are not normally distributed and there are quite many outliers (some of them are influential though). I have tried to change the logarythm, but i'm not sure, how to do that. I want also draw a plot picture in which logarythms of predictors x and y are changed. How could I do that?

Hello! Does anyone know of a handy way to wrap the names.arg text in a barplot? I'm creating a bar plot with rather long labels; I can adjust the margins, but I'd also like to have the text wrap to about 4cm. Thanks! Kyle H.

Hey, I was using lme and proc mixed in SAS to run a empirical bayesian model. I used the same method for both lme and proc mixed (the default REML). I got very similar, but not identical results. I am just wondering if anyone knows what the differneces may be between proc mixed and lme. Any thoughts would be appreciated! Thanks, Liz

Hi, I would like to draw a graph as follows: A simplified example is that on the X axis are different countries, I have several temperature measurements taken from each country and would like to plot these linearly above each country. So one would imagine that cold countries would have lots of points at lower temperatures and the opposite for higher countries with a few outliers. I am not sure

Hi, We were wondering how we could make a stacked frequency diagram such as this one: http://msemac.redwoods.edu/~darnold/math15/liz.pdf We don't necessarily need the shaded "balls", other characters would be fine, such as stacks of x's. David

Last week one of our clients reported trouble with a csv file I generated with write.table. He said that columns with quotes for character variables were rejected by their data importer, which was revised to match the way Microsoft Excel uses quotation marks in character variables. I explained to them that quoted character variables are virtuous and wise, of course, but they say Microsoft Excel
