Re: [R] Subsetting within xyplot()
See the description of the subset argument in ?xyplot
subset: logical or integer indexing vector (can be specified in terms
of variables in 'data'). Only these rows of 'data' will be
used for the plot. If 'subscripts' is 'TRUE', the subscripts
will provide indices to the rows of data before the
subsetting is done. Whether levels of factors in the data
frame that are unused after the subsetting will be dropped
depends on the 'drop.unused.levels' argument.
That is not what you are passing.

Re: [R] Subsetting within xyplot()
Try this:
xyplot(y ~ x , data = junk.frm, type = c("g", "p","smooth"), pch=20,
subset=z=="D" & y < 2)

[R] Subsetting within xyplot()
All,
I'm having problems w/ a simple attempt to subset an xyplot.
The first plot below is a plot of y versus x for certain values of a third
categorical variable z. Now I'd like to further restrict this to certain
values of variable y. Neither of the two attempts below work. Any
suggestions much appreciated. (note: I don't want to merely use ylim since
I have a loess plot and I want this to be calculated w/ the restricted
values).
Thanks,
David
