Plotting method for annotated heatmaps
Plotting method for annotated heatmaps
## S3 method for class 'annHeatmap' plot(x, widths, heights, ...)
x |
an object of class |
widths |
a numerical vector giving the widths of the sub-plots currently defined |
heights |
a numerical vector giving the heights of the sub-plots currently defined |
... |
extra graphical parameters, currently ignored |
This function displays an annotated heatmap object that has been previously generated by annHeatmap2 or on of its wrappers. The arguments widths and heights work as in layout.
x, invisibly returned. If widths or heights have been specified, they overwrite the corresponding items x$layout$width and x$layout$height in x.
## Define the map
require(Biobase)
data(sample.ExpressionSet)
ex1 = sample.ExpressionSet[51:85,]
map1 = annHeatmap2(exprs(ex1), ann=list(Col=list(data=pData(ex1))),
cluster=list(Col=list(cuth=3000)))
## Plot it
plot(map1)
## More heatmap, smaller dendrogram/annotation
map2 = plot(map1, heights = c(1,6,1))
## Compare layout before/after
with(map1$layout, layout(plot, width, height))
layout.show(4)
with(map2$layout, layout(plot, width, height))
layout.show(4)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
