[R] scaling axes when plotting multiple data sets

[Spencer Graves]

      I just did "?min" and found an argument na.rm, which when TRUE 
causes "min" to ignore NAs.  Also, "See Also" for "?min" mentions 
"range", which returns a 2-vector consisting of both min and max.  The 
function "range" also accepts the na.rm argument.  AND the documentation 
for "range" includes a simple example that seems to demonstrate exactly 
what you are requesting here. 

      hope this helps.
