...ther simplistic and arbitrary in terms of choices about how and where the weighed averages are computed. It seems to me that what I am doing is a kind of poor mans loess. Can anyone suggest a better way to deal with this analysis ? I have only a sketchy knowledge of loess.

Hello, I am looking for a measure of linearity in the relationship between two variables. Specifically, I have two variables for which the relationship is reasonably linear over a certain range of values, and then diverges from linearity at either end of the range, as one or other variable "saturates" at a maximum or minimum value. I want to identify the region of linearity, where

I think the problem is the way files are named on the Macintosh. On the Mac, the file separator character, which is "/" on unix and "\" on dos/windows, is ":". Also, the root directory doesn't start with the separator character, but instead just starts with the volume name, which is the name of the hard disk icon on your desktop, so if your file is in the top

Hello, I have installed the ROracle and DBI packages, and I want to access an Oracle database that is not on the same machine as the one I am running R on. I can access the database remotely with perl DBI and Java JDBC. Does anyone know if this is possible using R DBI/ROracle ? I have looked through the documentation and also tried to guess at things which might work, but with no success. I

[sorry, but this is a re-post - I forgot to set the subject line the first time around] Hello, I would like to access an Oracle database running on Solaris from R on my linux desktop. I have had a look at the R Data Import/Export manual, and downloaded RODBC and unixODBC, but I am still quite confused about how to proceed. It appears to me that I still need to get an Oracle ODBC driver, and

Hello, I have a 2 factor linear model, in which the only terms I am interested in estimating and testing are the interaction terms. I want to control for the main effects but have no interest in estimating or testing them. However, I would like an estimate of the interaction effects for every level of the interactions, whereas what I get is one fewer estimate than this, with the first level
