Hi All,

I am running a scatter plot and trying to add a best fit line.  I use an abline function, but get no line drawn over the points.  I also get no error.  I arm using V 2.10.0 on Windows 7.

Here is my code, including the SAS transport file import:

require (foreign)
require (chron)
require (Hmisc)
require (lattice)

clin  <- sasxport.get("y:\\temp\\subset.xpt")
attach(clin)


plot.new()
xyplot(jitter(b.lvef)~jitter(log.fgf), 
       main="Scatter Plot of Baseline Ejection Fraction\nby Log10 FGF-23",
       ylim=c(10,90),
       ylab="Ejection Fraction", xlab="Log10 FGF-23")

abline(lm(b.lvef~log.fgf))

Any suggestions appreciated.

Thanks,

Gerard
