[R-SIG-Finance] RQuantLib FixedRateBondYield close to maturity

[Terry Leitch]

Not sure, but maturity=effectivedate+1 . Since setllementDays=1, the bond matures on the same day you pay for it. Was that your intention?

Hi,
I try to back-out the yield from a US Treasury note giving clean price using the function "FixedRateBondYield".
The procedure generate an error (See below).

Is this a structural problem or could it be correct by changing the bond settings ( I tried several changes already)?
Thank you
Charles


In this reproducible example, I try to back-out the yield for a bond maturing on 31-Dec-2016 as of (value date) 30-Dec-2016 (Friday).

library("RQuantLib")

dateValue<-as.Date("2016-12-30")

setEvaluationDate(dateValue)
# US Treasury note fixed attributes
gen_bond_UST =list(asettlementDays=1,afaceAmount= 100,aperiod=3,acalendar="UnitedStates/GovernmentBond",adayCounter=2,
                   abusinessDayConvention=2 ,acompound = 1 ,aredemption=100 ,aissueDate=as.Date("2014-01-31"),aendOfMonth=0)

# Function
with(gen_bond_UST,FixedRateBondYield(price=100.0078,effectiveDate=dateValue,maturityDate=as.Date("2016-12-31") ,rates=0.00625,
                   calendar=acalendar,settlementDays=asettlementDays,faceAmount= afaceAmount,period=aperiod,dayCounter=adayCounter,
                   businessDayConvention=abusinessDayConvention ,compound = acompound ,redemption=aredemption,issueDate=aissueDate))

# output
Error in fixedRateBondYieldByPriceEngine(settlementDays, price, calendar,  :
