[R] scaling axes when plotting multiple data sets

[Benjamin M. Osborne]

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
