Re: [R] plot a vertical column of colored rectangles

Hi Nacho, You should look grid.rect or grid.polygon function from grid library. I attach you an example, you can play with this: dat - c(0,0,0,0,1,1,1,0,0,1) colour=ifelse(dat == 0, red, blue) library(grid) library(foreach) grid.newpage() vp1 - grid.layout(nrow = 1, ncol = 1,

Re: [R] plot a vertical column of colored rectangles

Hi, You could try grid.colorstrip() from the gridExtra package, grid.colorstrip(ifelse(dat, blue, red)) or grid.raster(), which should be more efficient, grid.raster(matrix(ifelse(dat, blue, red)), interp=FALSE, width=unit(1,npc), height=unit(1,npc)) HTH, baptiste On 15 July 2011 22:20,

[R] plot a vertical column of colored rectangles

Hi, I've been really struggling with this. If I have a vector like dat - c(0,0,0,0,1,1,1,0,0,0,1,1,0,0,0,1,0,0,0) I want to plot each element as a colored rectangle (red=1, blue=1) in the right order, so they all stack up forming a vertical column on the graph. Sort of like a building, with each
