[Gsoc-dowd] Thousands of graphics in examples pdf

[Peter Carl]

Dinesh,

Looks like you're continuing to make good progress!

I ran through check today and noticed a couple of things.  First, in the 
pdf that is generated of your graphic examples (which shows up in 
..Rcheck/Dowd-Ex.pdf), some of your functions are generating hundreds 
(maybe thousands) of individual graphs.  I suspect the issue is in the 
same functions that are identified as taking more than five seconds to run:

Examples with CPU or elapsed time > 5s
                               user system elapsed
GaussianCopulaVaR           62.140  0.004  62.229
KernelESEpanechinikovKernel 15.816  0.324  16.156
KernelESTriangleKernel      15.684  0.308  16.005
KernelESBoxKernel           15.060  0.312  15.515
KernelESNormalKernel        14.660  0.408  15.082
CdfOfSumUsingGaussianCopula  6.224  0.000   6.225

Second, the check process is reporting some latex errors (in 
..Rcheck/Rdlatex.log).  Those are mostly "Usage" lines that are too long 
- this is a minor, low priority thing but (if you have time) might make 
the resulting pdf a bit more readable.  I wouldn't worry about it unless 
you see issues in the pdf itself.

Let me know if you have any questions...
