Dear Dr. Murrell
Sorry to bother you at home, so to speak, but my emails to r-help@r-project.org
are falling into the void.
I am trying to make a multiple panel plot with 26 rows and 2 columns
with plots from a tool (genoPlotR) that is layered on grid. My code
and session info are below. When I execute the code, I get a single
plot in the center of the graphics page. I have tried various viewport
and pop/push/down/seekViewport commands. There must be something I'm
missing in the documentation, I believe what I have should work. I
have been able to find a few similar scenarios in the help archives
but enlightenment eludes me.
Could I get you to critique my latest version of the code below and
help me figure out how to combine multiple plots in columns and rows?
The code below produces a graphic with all the plots overlaid on the
left middle side of the graphics window. And I get the following
warnings repeated 50 times:

=gl,layout.pos.row=row,layout.pos.col=column,name=as.character(n)))

main=toupper(letters[n]),main_pos="left"
)
}
gl <- grid.layout(nrow=26,ncol=2)
pushViewport(viewport(layout = gl)
segs <- c(segs.cys.115,segs.cys.196,segs.asp.388,segs.asp.1060,segs.gly)
sapply(segs,plotpush,n=1:26,letter=1:26,row=1:26,column=1,layout=gl)
