Hi, I was trying to get a graph in lattice with the following data frame (7 rows, 5 cols): chr start1 end1 meth positive 1 ? 1 ? ? 10 ? 20 ?1.5 ? ? ? ?y 2 ? 2 ? ? 12 ? 18 -0.7 ? ? ? ?n 3 ? 3 ? ? 22 ? 34 ?2.0 ? ? ? ?y 4 ? 1 ? ? 35 ? 70 ?3.0 ? ? ? ?y 5 ? 1 ? ?120 ?140 -1.3 ? ? ? ?n 6 ? 1 ? ?180 ?190 ?0.2 ? ? ? ?y 7 ? 2 ? ?220 ?300 ?0.4 ? ? ? ?y I wanted the panels to be organized by 'chr' - which is ok. Further, I wanted the lines to be discontinuous. For example, in the first row, the x co-ordinate starts with a value of 10 (2nd column) and ends with a value of 20 (3rd column). The corresponding y value for this range of x values is 1.5 (4th column). Similarly, for the same panel (i.e chr=1), the fourth row would have x co-ordinate range from 35 to 70 with a y co-ordinate of 3.
You could do it with library(latticeExtra) segplot(meth ~ start1 + end1 | factor(chr), bar, type = "g") but as Baptiste said, ggplot2 can do conditioning just as well. -Deepayan
If it were only one panel, a similar result could be achieved for the data x2:
x2
?chr start1 end1 meth positive 1 ? 1 ? ? 10 ? 20 ?1.5 ? ? ? ?y 4 ? 1 ? ? 35 ? 70 ?3.0 ? ? ? ?y 5 ? 1 ? ?120 ?140 -1.3 ? ? ? ?n 6 ? 1 ? ?180 ?190 ?0.2 ? ? ? ?y ## Code courtesy of BAPTISTE AUGUIE library(ggplot2) ggplot(data=x2) + ?geom_segment(aes(x=start1, xend=end1, y=meth, yend=meth)) - Can I get lattice to do a similar graph for the panels? thanks! ? ? ? ?[[alternative HTML version deleted]]
