Scaling X axis from -1 to 1
Dear Jim, I cannot find the function "rescale". Does it belong to any particular package? - Gundala Viswanath Jakarta - Indonesia

Hi, I have a density plot in which the x axis ranged from 0 to 2000. How can I scale the data so that the x-axis is scaled in -1 to 1 form?
Hi Gundala,
If your data is named "mydata":
mynewdata<-rescale(mydata,c(-1,1))
This will linearly transform "mydata" into the range -1 to 1. You may also
want to manually create the axis on the plot:
plot(mynewdata,axes=FALSE,...)
box()
axis(1)
axis(2,at=c(-1,0,1),labels=c("0","1000","2000"))
If you want the original values.
