Hi,
I wanted to make a graph with the following table (2 rows, 3
columns):
a b c
x 1 3 5
y 5 8 6
The first column represents the start cordinate, and the second
column contains the end cordinate for the x-axis. The third column
contains the y-axis co-ordinate. For example, the first row in the
matrix above represents the points (1,5),(2,5), (3,5). How would I
go about making a discontinuous graph ?
thanks!
coords <- read.table(textConnection("a b c
x 1 3 5
y 5 8 6"), header=TRUE)
plot(NULL, NULL, xlim = c(min(coords$a)-.5, max(coords$b)+.5), ylim=c
(min(coords$c)-.5, max(coords$c)+.5) )
apply(coords, 1, function(x) segments(x0=x[1],y0= x[3], x1= x[2],
y1=x[3]) )
Oh, *that* kind of graph!
... my high-school English teacher once said that "all communication
is miscommunication" because we each interpret things according to our
own experiences, etc ... I guess that goes to show:
(i) me that he was right (once again);
(ii) you what I've been working on lately :-)
Sorry for the line-noise,
