Thanks Duncan and David
for opening my eyes :-). It took quite a while but I think I learned a
lot about lm today. I used your advice to produce "added variable
plots" as mentioned here [1], [2]. I would bet someone did it in R
already (may leverage.plot in car) but it was worth doing it myself.
erm2(fit, "x1")
removeTerm3(fit, "x1")
removeTerm4(fit, "x1")
removeTerm5(fit, "x1")
Any help appreciated,
kind regards,
Karsten Weinert

Hello,
at the Rgui command line I can easily remove a term from a fitted lm
object, like
fit <- lm(y~x1+x2+x3, data=myData)
update(fit, .~.-x1)
However, I would like to do this in a function with term given as string, like
removeTerm <- function(linModel, termName) { ??? }
removeTerm(fit, "x1")
Hello group,
recently I read about the SweaveListingUtils package and now I would
like to try it out. However I can not make it run...
Below is a minimal example. The problem seems the following line,
generated by the package:
\ifthenelse{\boolean{swe...@gin}}{\setkeys{gin}{width=0.6\textwidth}}{}

Hello,
my dataset is already aggregated: I have two categorical variables, say
"continent" and "country" and one non-negative metric variable "population".
Now I would like to produce a mosaic plot which uses "population" to
determine how large each area of the plot is.
In other words, I fail to f
show the console?
Any hint appreciated,
Karsten Weinert.
