Dear Bob

We do not have your data so it is hard to be sure but plot() takes two parameters for the data x and y so when you give it three you are confusing it into thinking one of them is something else.

What exactly were you trying to do with the failed command?

Please consider the following R statements:

     [1] 1632
     > length( MyData$NWorthSm )
     [1] 1632

     > plot( x, MyData$NWorthSm, type="l" )
     > plot( x, MyData$NWorth, MyData$NWorthSm, type="l" )

All of the above statements work except for the last one. The last one produces the following message:

     Error in plot.window(...) : invalid 'xlim' value

So I then tired this:

     > xlim1 = c(0, 5000)
     >plot( x, MyData$NWorth, MyData$NWorthSm, type="l", xlim = xlim1 )

Which produced the following error message:
     Error in plot.window(...) : invalid 'ylim' value

So, I tired this:
     > ylim1 = c(0,9000)
    > plot( x, MyData$NWorth, MyData$NWorthSm, type="l", xlim = xlim1, ylim = ylim1 )

Which produced the following error message:
     Error in strsplit(log, NULL) : non-character argument

I would like to know what I am doing wrong.

Thank you,
Bob
