I had a small battle with public key authentication today at the end of which I realized that the problem was the permissions on my home directory (previously I though ~/.ssh was all that mattered. You learn something new every day!). While I was trying to track this problem down, I used ssh -v and sshd -ddd to get as much information as possible about why my public key wasn't

R Users: My question is probably more about elementary statistics than the mechanics of using R, but I've been dabbling in R (version 2.2.0) and used it recently to test some data . I have a relatively small set of observations (n = 12) of arsenic concentrations in background groundwater and wanted to test my assumption of normality. I used the Shapiro-Wilk test (by calling shapiro.test()

R users: I'd like to get some insight on an error I encounter when attempting to work with two moderately sized sets of time series data. FYI - I'm using the following versions of R and supporting packages on a Windows 2000 OS: - R version 2.4.1 (2006-12-18) - zoo version 1.2-2 - chron version 2.3-10 The two time series I'm working with are from the summer of 2004 and are: 1.)

It occurred to me that it would be extremely convenient if I could add a "knock" configuration option for the host to my ~/.ssh/config file and never think about this again (rather than creating a shell script to accomplish this behavior,

Thus far, I've managed to import the data, log-transform the concentrations, assign coordinates, generate and fit a variogram model and
