derivmkts 0.2.2.1

Primarily a maintenance release with one new feature (tidy output)

• Added tidygreeks parameter to greeks function to return output in tidy format. This is FALSE by default, for compatability. Still need to add test for this output

• Fixed: if a parameter in the function passed to greeks uses the index “i”, the eval step in Greeks fails (because the eval loop also uses “i”. The index variable cannot be z91k25

• Fixed: spurious “break” in implied.Ri

derivmkts 0.2.2

• Functions for compound options (call on call, call on put, etc.)

• Binomplot: Option for log y axis

• New vignette discussing alternative ways to write vectorized functions

derivmkts 0.2.1

• Binomopt

  • Fixed: default dn=1.5 in binomopt and binomplot
  • Added “returnprice” parameter to binomplot
• greeks
  • Simplification of Greeks discussion in README.Rmd
  • Greeks function ignores theta when appropriate (perpetual options)

• callperpetual and putperpetual functions added to barriers.R

• Asian options

  • Added individual geomavgpricecall, geomavgpriceput, geomavgstrikecall, and geomavgstrikeput functions.
  • Fixed greeks functionality for asian options
