...t the IP address that assigned to my VM. I know I can configure static ip but I like to assign ip dynamically to avoid mgmt cost. Does anyone know where the dhcp log is? My KVM host is running Ubuntu Raring (13.04). It does not have file /var/log/daemon.log as some online doc mentioned. Thanks, ~Jianfeng >

Dear all, This is a simple probability problem. I want to know, How to generate a normal distribution with mean=1, min=0.2 and max=0.8? I know how the generate a normal distribution of mean = 1 and sd = 1 and with 500 data point. rnorm(n=500, m=1, sd=1) But, I am confusing with how to generate a normal distribution with expected min and max. I expect to hear your directions. Thanks in

Thank you Daniel. How difficult to extend libvirt for this? One critical application on my VM needs to turn vnet_hdr off. I can switch to use qemu directly. However, in that way I will lose all the nice things provided by libvirt. Thanks, ~Jianfeng On 3/3/14 3:53 AM, "Daniel P.

Dear Mao Jianfeng, "r-help-owner" is not the place for help, but: r-help at r-project.org (CC-ed here) In any case, strsplit() does the job, i.e.: > unlist(strsplit("BCPy01-01", "-")) [1] "BCPy01" "01" You can work with the whole variable, like: splitpop <-...

Dear R-help listers, I am new. I just want to get helps on how to plot two histograms overlapped in the same plane coordinate. What I did is very ugly. Could you please help me to improve it? I want to got a plot with semi- transparent overlapping region. And, I want to know how to specify the filled colors of the different histograms. I also prefer other solutions other than ggplot2.

Hello dear R-users, I have a tricky problem of data manipulation with R. Although it seems very easy, I can not solve it by myselves. The problem is a variable in my dataset is usually be readed as "factor" (variable mode), however I want it be a "numeric" one. I want to know how can I define an variable/column in a dataframe as numeric mode, after I imported a large
