blotched y-axis text in plot function
Hi List, I have recently upgraded to opensuse10.2 and R 2.5 (compiled from source). Now, whenever I use plot the y-axis and labels are black blotches while x-axis and labels are fine. Using demo(graphics) this occurs with plot/boxplot/hist/pairs/coplot but not in the pie graphs and in the "The level of Interest in R" plot, which uses axis to define the y-axis. I presume this has to do with the font handling of linux/R. But, being no...

mu^2(1-mu)^2 variance function for GLM
Dear list, I'm trying to mimic the analysis of Wedderburn (1974) as cited by McCullagh and Nelder (1989) on p.328-332. This is the leaf-blotch on barley example, and the data is available in the `faraway' package. Wedderburn suggested using the variance function mu^2(1-mu)^2. This variance function isn't readily available in R's `quasi' family object, but it seems to me

[newbie] failure to plot a RasterLayer with raster::plot or fields::image.plot
...es the page enough (e.g., to 800%), one sees + the space inside the US-map borders is white, which is good, since the data is marine + there is a roughly Canadian-shaped white blob oriented correctly relative to the CONUS blob, and similarly a roughly Mexico-shaped blob + there are green blotches corresponding to the elevated emissions off the Pacific coasts of Canada and Mexico, and they are situated similar to their position in the unprojected world map https://github.com/downloads/TomRoche/GEIA_to_netCDF/GEIA_N2O_oceanic.pdf So I'm thinking that the data might have regridded...

glm questions
Greetings, everybody. Can I ask some glm questions? 1. How do you find out -2*lnL(saturated model)? In the output from glm, I find: Null deviance: which I think is -2[lnL(null) - lnL(saturated)] Residual deviance: -2[lnL(fitted) - lnL(saturated)] The Null model is the one that includes the constant only (plus offset if specified). Right? I can use the Null and Residual deviance to
