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(
Hello,
You are calling plot.default with 4 arguments.
The first 2 are x and y.
The 3rd is type.
So MyData$NWorthSm becomes the 4th, xlim.
When you pass xlim a value, MyData$NWorthSm becomes the next one, ylim.
Etc, etc, etc.
It will throw the errors in the order of the arguments you can see in
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:
> x = seq(1:1632)
> length( MyData$NWorth )
[1] 1632
> length( MyData$NWorthSm )
[1] 1632
> plot( x, MyData$NWorth, type="l" )
> plot( x, MyData$NWorthSm, type="l" )
> plot( x, MyData$NWorth, MyData$NWorthSm, type="l" )
