Well, you didn't send a text file with the contents of "daily_records.csv";
rather you sent a text file that was R code that would return a data object. I
assigned it to the name `rain` before I realized it was a two item list. I then
fixed the problems that assignment and the factor Dates presented so that I
could then give a `data=rain` parameter to the xyplot function.

Notice that the formula has just the column names rather than using `$`. But
need to give `rain$date` to functions in hte scales list. It always seemed to
me that the evaluation of names inside the scales list should also be evaluated
inside the `data` environment but Deepayan didn't design it that way, so you
need to "reach out" to get them pulled back in.

So typing ?xyplot at the console doesn't bring up a help page? That would imply

David,
I left the station as a factor and changed the date using
as.Date(as.character...) and the amount using as.numeric.
When you do that you can see the only the first item in the length2 list
is likely to be useful:
I'm not seeing to what the 'List of 2' refers in the data.frame.
This is the script I sourced:
rain <- read.csv("daily_records.csv", header=T, sep=",")
require(lattice)
rain$date <- as.Date(as.character(rain$date))
rain$amount <- as.numeric(rain$amount)
xyplot(rain$amount ~ rain$date | rain$station, main="Weather Stations", xlab="Date",
ylab="Amount (inches)", pch=20, col=132)
What did I do incorrectly here?
And the date column is a factor. Fortunately the as.Date.factor function
doesn't need as.chaacter anymore:
Oh. Thanks.
The place on the ?xyplot help page to look is in the section on `scales`.
There's no difficulty using 'rot' as long as it is in the correct place
which in this instance is `x` sublist of the `scales` list
xyplot(amount ~ date | station, data=rain, main="Weather Stations",
xlab="Date", ylab="Amount (inches)", pch=16, col=132,
scales=list(y=list(at=0:4),
x=list(at=seq(min(rain$date), max(rain$date), by='week'),
rot=90) )
)
That's what I missed: where the scales command is placed, and
understanding how to use all the components.
I need to figure out why I'm no longer seeing the help files. As far as I
know they should be loaded when I invoke R.
Thanks very much,
Rich

The place on the ?xyplot help page to look is in the section on `scales`.
There's no difficulty using 'rot' as long as it is in the correct place which
in this instance is `x` sublist of the `scales` list
xyplot(amount ~ date | station, data=rain, main="Weather Stations",
xlab="Date", ylab="Amount (inches)", pch=16, col=132,
scales=list(y=list(at=0:4),
x=list(at=seq(min(rain$date), max(rain$date), by='week'),
