It was arbitrary data and I made a mistake.  Thanks for your help
nonetheless.
I solved the problem using matpoints, which does the job quite nicely:

> lx100=c(1,1,1,.8,.5,.4,.2,0)
> day100=c(0,1,2,3,4,5,6,7)
> lx90=c(1,1,1,1,.9,.8,.6,.4,.2,.1,0)
> day90=c(0,1,2,3,4,5,6,7,8,9,10)
> lx0=c(1,1,1,1,1,1,.9,.9,.8,.8,.6,.5,.4,.3,.2,.1,.1,0)
> day0=c(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17)

> lx = cbindX(data.frame("100%"=lx100),data.frame("90%"=lx90),data.frame("0%"=lx0))
> day = cbindX(data.frame("100%"=day100),data.frame("90%"=day90),data.frame("0%"=day0))
