I'm getting an interesting error:
> plotxy <- function(x, ...){
+ plot(x, ...)
+ }
> XY <- data.frame(x1=1:3, y1=4:6)
> plotxy(y1~x1, XY, xlim=c(0, max(x1)))
Show Traceback
Rerun with Debug
Error in eval(expr, envir, enclos) : object 'x1' not found
The following work:
plotxy(y1~x1, XY)
plot(y1~x1, XY, xlim=c(0, max(x1)))
Within "plotxy", R can't find "x1" to compute "xlim". Is there a
way I can make x1 available to xlim?
Thanks,
Spencer
