similar to: adding year information to a scatter plot

Dear R Users, I have the following data frame: v1 <- c(rep(10,3),rep(11,2)) v2 <- sample(5:10, 5, replace = T) v3 <- c(0,1,2,0,2) df <- data.frame(v1,v2,v3) > df v1 v2 v3 1 10 9 0 2 10 5 1 3 10 6 2 4 11 7 0 5 11 5 2 I want to add a new column v4 such that its values are equal to the value of v2 conditional on v3=0 for each subgroup of v1. In the above example, the

Dear All, I am economist and working on poverty / income inequality. I need descriptive statitics like the ratio of education expentitures between different income quintiles where each household has a different weight. After a bit of google search I found 'Hmisc' and 'quantreg' libraries for weighted quantiles. The problem is that these packages give me only weighted quintiles;

Hello everyone, This is my first post to the mailing list, so I hope I am posting my message the correct way. I am trying to present my dataset in a 3d scatterplot using cloud() in the {lattice} package. I hope to explicitly identify a subset of my observations. The observations in this subset need to satisfy the following critera (values on x,y, and z axes above a certain cutoff value). It

Hi there, I hope I can get advice regarding the calculation of leverage values or studentized residual values of a non-linear regression model. It seems like rstudent() does not work on a nls object. Many thanks in advance! Best regards, Xingli

Hi, Im trying to compile kernel 3.0.4 inside Centos 5 DomU The steps I do are Make bzImage Make modules Make modules_install Depmod -a mkinitrd /boot/initrd.img-3.0.4 3.0.4 but them im getting this -bash-3.2# mkinitrd /boot/initrd.img-3.0.4 3.0.4 ls: /etc/modprobe.d/*.conf: No such file or directory No module ehci-hcd found for kernel 3.0.4, aborting.

Hey everyone, I have a question about vif-common.sh. I run multiple bridges attached on dummy interfaces, which allow me to put guests in seperate subnets (routed through the dom0). As you might expect I already have quite extensive iptables scripts to accomidate this kind of routing. I was just hoping someone on this list can confirm, that I understand what the iptables lines in vif-common.sh

Hi, For the past day, I have been researching about making dovecot to support mailfront (http://untroubled.org/mailfront/) imapfront-auth natively and able to use mailfront imapfront-auth with dovecot imap v1.2.16 without starting any dovecot related services and no /etc/dovecot.conf file is required. More information about this can be read at:

Hey hope this opne is a "make senser". Has anyone tried the "Subject line" combo?, I''ve compiled a dozen src.rpm kernel 3.0 and 3.1 packages with no luck to try native upstream Dom0 kernel support with no success, just a kernel oops and constant reboots. I followed Fedora''s wiki on building a custom kernel, even used F16''s .config which also was a

I've been running samba servers with 200+ W98 machines for some time. I'm changing to W2k and everything was going fine. I've upgraded 40 boxes. One W2k box has started announcing itself as a local master browser for one of the workgroups. A samba server thinks it is master, forcing election. Samba will stop being the LMB for about 3 minutes and then will re-establish itself as

Hej folks, I''m messing around with DRBD once again but with a new Xen 4.1.2 installation using the XL toolstack instead of the xend daemon. However, after getting my DRBD installed and a device operational, trying to create a domU using the drbd block device doesn''t want to work: xl create -c test.cfg Parsing config file test.cfg Unknown disk type: drbd My config has: disk

Hi R-users, I would like to calculate weighted mean of several variables by two factors where the weight vector is the same for all variables. Below, there is a simple example where I have only two variables: "v1","v2" both weighted by "wt" and my factors are "gender" and "year". set.seed(1) df <- data.frame(gender = rep(c("M",

Hi As you may''ve seen from my last posts I''m struggling to get the setup on my subject line to work without flaws. I''ve tried compiling the Kernel from Source, I''ve also tried Fedora 14, which has a flaky pv_ops Dom0 kernel which DOESN''T work at all, but none of these seem to work. I''m a mid-time XEN user, I just love it and want to stay

I'm new to R and have not been able to find what I am looking for online. I found the system command but that seems to be used for getting lists of directories, etc. I am trying to replicate something that I used to do in SAS. I am simulating some data (which I can do in R with a particular package) and then trying to call an outside program to fit a specific model to the data. In SAS, the
