6546 .12 21

I need to plot a grpah for above with position as x - axis and two variables
with as line on the same plot. I have 5 million records. How can i
implement it efficiently.
Hi Manish,
You can plot this with twoord.plot (plotrix):
position<-c(2,3,12,425,6546)
var1<-c(.1,.29,.56,.34,.12)
var2<-c(10,89,100,1234,21)
library(plotrix)
twoord.plot(lx=position,ly=var1,rx=position,ry=var2)
but with 5 million records you will just have a jagged block of color. I
think ghostwheel's suggestion of reducing the number of points is very
sensible.
Jim
