Hi, I am a student of Earthquake Engineering, and am new to R. Currently I try to run nonlinear regression analysis by R. My data has three variables: X, Y, and Z. Z is a function of (X, Y). My R script is as below. rm(list=ls()) # read in data Alldata <- read.table("~/Documents/R/Wu_data.dat", header=TRUE) # assign variables Z <- Wu[[1]] # N1,60 X <- Wu[[2]]

Hi, I am new to R. I don't have strong background of statistics. I am a student of Geotechnical Engineering. I tried to run a nonlinear regression for a three-variable function, that is N = f(CSR, ev) # N is a function of CSR and ev, and N = CSR/(A +B*CSR), wherer (A,B) are function of ev. N, CSR and ev are observed in the experiments. Following is my R script. rm(list=ls())

Hi I am using igraph package in R. My goal is to read a network (in "pajek" format) and decompose the network into components. In addition, I am also interested in sending this output to to a file.

Hello Everyone, I am using R for creating heatmap from a square matrix.

Hi, In my analysis of impacts of insecticide-treated bednets on malaria, I look at the relationship between malaria incidence and mosquito behaviors. The condensed data set is copied here. Ordinary regression (lm) shows that Incidence was negatively related to Mortality. This makes sense because the latter reflected the strength of killing mosquitoes by insecticide-treated nets. Since the

Hi R-masters! I have a problem and need your help. I have 9 discrete variables with 2 levels each.

I am using shorewall-4.2.5-1 on RHEL-5.2 for a MultiISP connection. Everything works great. I run vpn, proxy, mail relay on the firewall. Hence I do the application level management. So far I was using third party script "gwping" for my failover mechanism. Just wondering if shorewall has any native programs to handle fail over ? Thank you Chakri

Hi, I wrote a program in PERL which creates a file with .net extension (.. xyz.net).
