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

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
summary: spatial data to be input to a regional-scale environmental
model must (1) be converted to netCDF and then (2) "regridded" (cropped,
projected, increased resolution). In a public git repository
https://github.com/TomRoche/GEIA_to_NetCDF
I have R code (with bash drivers) that does the conversion step, and
plots the converted output, apparently correctly. However attempts to

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
