Oliver,
I am attaching an HTML document in which I have plotted -2Log(x) vs. x. If you
examine the plot you will see that -2Log(x) can be negative. Since -2Log(x) is
part of AIC and BIC, AIC and BIC can be negative.

SQL, you can use SQL to manipulate R data frames using the sqldf package
which provides an interface to lower level RSQLite (and RMySQL in the future)
routines. The following examples use SQLite underneath:

Hi Greg,
Actually, I'm using the scatterplot function in the car namespace. My
understanding is that the scatterplot is turned into a boxplot when the x
variable is a factor, but I can't see that in the code of the function.
I've successfully modified the function to output regression stats
Your columns are factors, not character strings. Use as.is = TRUE as
an argument to read.table. Also its a bit dangerous to use T although
not wrong. Its safer to use TRUE.

A matrix is for situations where every element is of the same class
but your columns have different classes so use a data frame:

subset(DF, a %in% 11:13)
subset(DF, a %in% c(0, 11:13)) # same

Dear UseRs,
I would like to know which function is the most efficient in finding
convex hull of points in 3(or 2)-dimensional case?
Functions for finding convex hull is the following:
convex.hull (tripack), chull (grDevices), in.chull (sgeostat),
convhulln
Try this:
library(zoo)
plot(na.approx(zoo(as.matrix(data[-1]), data[,1])), plot.type = single)
See ?na.approx, ?plot.zoo, ?xyplot.zoo and vignette(zoo)

Thanks a lot Gabor, that was very helpful. All sorted now!

Phil,
If you have only a list of addresses and nothing else - i have to recognize i
am lost. But if you have more info you can use a GIS software and it will
calculate your distance automatically for all your addresses. To have your
distance in miles or Km you need to have a projection in
6. set the reset.par argument to FALSE in calling scatterplot as it
states in the documentation for scatterplot. (still look at the help on
'xpd' argment to par if you want to add text to the margins).
Hi Greg,
That seems to have done it partly. I set it to false once and then I could

The posting guide (a link at the bottom of every e-mail from

trying to do.
Without an example, we have to guess at what you are trying to do.
I am still guessing
Yes but delete does not return anything so its not useful. In the devel
version of sqldf you can pass multiple command so try this using the
builtin data frame BOD noting that the record with demand = 8.3 was
