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.
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!
