Re: [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.

1) When adding additional data sets to a plot using "plot" followed by "lines",
is there a way to automate the scaling of the axes to allow for all data sets
to fit within the plot area?
2) I attempted to solve this by setting
xlim=c(min(c(data1,data2,data3)),max(c(data1,data2,data3)))
however, there are some NAs and Infs in these data sets, and min(data1) and
max(data1) both return NA, as with data2 and data3.  (These are time series).
Thank you,
Ben Osborne
