[R] Problem with Plotting in R

[MacQueen, Don]

You haven't described what you are trying to get with the command that doesn't work. My guess is that this might be what you want:

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

However, you might also have to calculate and supply a for the ylim argument to plot().

    Please consider the following R statements:
    
         > x = seq(1:1632)
         > length( MyData$NWorth )
         [1] 1632
         > length( MyData$NWorthSm )
         [1] 1632
         > plot( x, MyData$NWorth, 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
