Greetings to the help mailing list.
I am in the process of translating a large graphic from xyplot to ggplot2 (13
columns by about rows).
I have been unsuccessful trying to understand how to place the following text
strings after three days of:
* Perusing Wickham's "gg2plot" book;
* Searching his site for gg2plot and qplot;
* Reviewing the "man pages" for gg2plot;
* Searching the R archives.
Problems are:
* Translate the xyplot statement
"xlab.top = c("long string", gpar(fontsize = 10, fontface = "bold x=0,
y=-1, just = "left"))"
to add a secondary x-axis to the top of my plot.
(This may have something to do with "strip.text.x" but I just cannot make
that work. Trying
several alternatives I keep getting error messages related to "Error in
grobName(grob, prefix) :
Invalid 'grob' argument", but "Error in grobName" didn't show up in
searched of the archives.)
* Translate the xyplot statement
"sub = c("not so long string, gpar(fontsize = 8, fontface = "plain",
x=0.05, y=1, just = "left"))
to add a "footer" to the plot.
* Split the lattice over multiple pages (each pages having three rows each) as
xyplot allows using
"layout = c(13,3)"
(noting the ggplot2 "layout", such as vplayout, seems useful only for
multiple plots on one screen /
page rather than splitting a single plot over multiple pages.)
(I could also do this by brute force, if needed.)
My thanks to all,
