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
