[R] Problem with Plotting in R

[Rui Barradas]

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 
?plot.default:

## Default S3 method:
plot(x, y = NULL, type = "p",  xlim = NULL, ylim = NULL,
      log = "", main = NULL, etc, etc, etc)


So now if you pass a log = <something>, it's the time for argument main.

Revise the reason why you are passing MyData$NWorthSm.


Hope this helps,

Rui Barradas
