Suppose you want tick marks at every half hour:
ticks = seq(as.POSIXct('2010-02-22 12:00:00 PST'),
as.POSIXct('2010-02-22 17:00:00 PST'),by='30 min')
dotplot(Name ~ Time, data = C, horizontal = TRUE,scales=list(x=list(at=ticks)))
Hope this helps.
Thanks Phil, I was also trying to get at something like that but couldn't
quite figure it out as quickly.
Mikkel, I guess for your specific example you would need to define ticks
like this:
ticks = seq(min(C$Time),max(C$Time),by='30 min')

The problem you have is with '5 a = 10'. Such double sided inequalities are
used in mathematics but not in R. Here you only need the first part, but if
you did need both you would need to write
5 a a = 10

Hi Sergio,
Having singular Dmat is certainly a problem.
I can see two possibilities:
1) try to eliminate X1,...,X9, so that you are left with P1,...,P6 only.
2) if you can not do this, add eps*X1^+...+eps*X9^2 to your matrix Dmat so that
it is positive definite (eps is a small positive number).

to a language, it is often not easy to know where to start in the
available documentation. It's hard to RTFM when one does not know which

in both locations and will therefore return the first match:
match(TazProperties..$Props,TazProperties..$Props)
