Performance Analytics has Display relative performance, Calculate Downside Risk, Show relative return risk, Compare distributions

If you try out this R package and tutorial:

http://cran.r-project.org/web/packages/PerformanceAnalytics/vignettes/PA-charts.pdf

You will find this a very impressive package. Even Matlab could not do any of this functionality so easily. What is even more impressive is this is all for free. How much would Mathworks charge for this?

http://www.r-bloggers.com/principal-component-analysis-use-extended-to-financial-economics-part-2/

For part 1 to create data, use http://www.nseindia.com/content/indices/ind_cnx500.htm, click Daily Return values and select period. Download as a CSV to be named Returns_CNX_500.csv. It appears to load fine. You will also need to create a matrix called return1 before executing the code.

For part 2, you need to download MIBOR.CSV from http://dl.dropbox.com/u/20480592/MIBOR.csv

Other than that, the code in part 2 does work!

This also contains some great metrics where you can instantly capture things llike realized volatility, spread, trade direction, bid/ask spread, calendar patterns with tick pattern

All I can say is wow!

‘World’s best quant’ Peter Carr reveals his toolchain of R packages for his research

IMPORTANT NOTE: This should make reference to Peter Carl not Carr

‘World’s best quant’ Peter Carr reveals his toolchain of R packages for his research

quantmod
indexes
RTAQ
xts
…
Example R Packages
TTR
signalextraction
…
quantstrat
quantmod
lspm
