RPgSQL etc seem now to be unsupported.
As for ODBC, there is some information in the README *but* setting up ODBC
is not an R question. Once you have a working connection (tested by say
isql -v foo), then odbcConnect(foo) will work too. There is lots of
documentation on the unixODBC site.

Many thanks to all who replied to my e-mail. My problem was that I
had not known about the approx function.
By the way, if I have x - c(1990,1994,1995,1997), is there an
automated way to fill in the gaps, i.e., to get
c(1991,1992,1993,1996)?

I think I'm missing something tonight in the usage of 'legend':

What am I doing wrong?

Hello everybody
thanks for your help with my R CMD check problem. The file
Davies-Ex.Rout does indeed contain a transcript of the examples.
I've found the .Rd file that contains the problem. The relevant
command executes perfectly when I cut-and-paste it onto the R command
line, but not when
legend(locator(1), month.abb[1:5], fill=T, col=1:5)
gives me 5 black boxes.
Try:
legend(locator(1), month.abb[1:5], fill=1:5)
What am I doing wrong?
The T is interpreted as (equal to?) a 1, so you're requesting the
boxes to be filled with color 1, which is black.
