Greetings
I am trying to make a multiple panel plot 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 pop/push/down/seekViewport commands at the end of
the plotpush method. There must be something I'm missing in the
documentation, I believe what I have should work. I haven't been able
to find a similar scenario in the help archives.
Could I get someone to critique my code and help me figure out how to
make multiple plots in columns and rows?
Thanks
Mike
plotpush <- function(x,n,letter,row,column) {
pushViewport
(viewport
(layout.pos.row=row,layout.pos.col=column,name=as.character(n)))
plot_gene_map
(dna_segs=list(x[["seg"]]),annotations=x[["annot"]],dna_seg_scale=T,
scale_cex
=
1.4
,dna_seg_line
=F,plot_new=FALSE,scale=F,arrow_head_length=1,annotation_cex=1.4,
main=toupper(letters[n]),main_pos="left"
)
popViewport(0)
}
pushViewport(viewport(layout = grid.layout(nrow=26,ncol=2)))
sapply(repeats,plotpush,n=1:26,letter=1:26,row=1:26,col=1)
sapply(repeats,plotpush,n=27:52,letter=1:26,row=1:26,col=2)
