facet

[J H]

I am using facet to plot box plots.  the facets are separated by 2 states, however, one of the x axis categories does not apply for one of the states. Since there is no data for that category.  I do not want to show it at all in the plot.  Is there a way to limit that?  here is the code and data.  Basically I don't want category "B" to be show for state NY.

Thanks,

CODE
ggplot(table, aes(x=Category, y=Value, fill=Category)) + geom_boxplot()+ facet_grid(.~ State)

DATA

State	Value	Category
CA	323	A
CA	23	A
CA	42	A
CA	4	A
CA	2	B
CA	42	B
CA	342	B
CA	4	B
CA	23	C
CA	42	C
CA	2	C
NY	3	A
NY	2	A
NY	4	A
NY	2	A
NY	342	A
NY	3	A
NY	23	C
NY	42	C
NY	3	C
NY	2	C
NY	32	C
NY	3	C

See ?facet_grid. There is a `scales` argument. You want "free_x" in this case.

Read the next argument to `facet_grid`, `spaces`. Also, be sure to include the group when you respond to emails.

Doug, Thanks.  However one other question.  While this does the trick it makes the box plot much larger in comparison to the other boxplots.  Is there a way to force the width of the boxplot to be the same?  Thanks. J

Ok thanks Doug. Works fine now. Thanks for all the help.
