Re: [R] hatching posibility in Panel.Polygon
Hi, library(gridExtra) example(patternGrob) provides some patterns to fill a rectangular area using Grid graphics. It could in theory be used in lattice. I wouldn't use it either, but I can imagine how it might be useful on very special occasions.

Re: [R] hatching posibility in Panel.Polygon
Tufte discusses hash lines in his book The Visual Display of Quantitative Information and does a better job of it than I can. The short version is that the hashing can actually produce optical illusion effects that distort the information. (and often don't copy well either). Printing and copying are good things to think about in generating graphs, but I think that using shades of gray, or no fill with labels, or other options are still much preferable to hashing. Consider making multiple simple graphs rather than one all inclusive complicated graph. -- Gregory (Greg) L.

Re: [R] hatching posibility in Panel.Polygon
Hopefully the right now will be a forever. The fact that trellis graphics do not support hatching is a conscious decision or feature, not a bug or missing feature to be corrected some day (at least I for one will be disappointed if Deepayan (or someone else) gives in and implements it). Have you tried using a partially transparent color for the fill so that the below section shows through? I would prefer that to hatching patterns. -- Gregory (Greg) L.

[R] hatching posibility in Panel.Polygon
Hatching with lines can be done in polygon function using density and angle arguments. Is similar possibility of hatching polygons available when using panel.polygon while trying to plot in panels using lattice? Many thanks in advance for your help.
