Is there actually a way to do this?
Thank you.

How to automate this model selection algorithm?
I've got a complicated semi-parametric model that I'm fitting with
mgcv. I start with a model based on theory. Its got lots of
interaction terms. I want to winnow it down: removing each interaction
term or un-interacted main effect one by one, checking the AIC, and
retaining the model that gives me the lowest AIC. I then want to repeat
the procedure on the retained model.
Here is

Partial matching performance in data frame rownames using [
Dear Ivan,
thanks a lot, that is helpful.
Still, I feel that default partial matching cripples the functionality
of data.frame for larger tables.
Thanks again and best regards

FW: Selecting undefined column of a data frame (was [BioC] read.phenoData vs read.AnnotatedDataFrame)
Hi all,
What are current methods people use in R to identify
mis-spelled column names when selecting columns
from a data frame?
Alice Johnson recently tackled this issue
(see [BioC] posting below).
Due to a mis-spelled column name ("FileName"
instead of "Filename") which produced no warning,
Alice spent a fair amount of time tracking down
this bug. With my fumbling fingers
