Hi all,
why doesn't something like this does not work?
speedy -
(sdata$VaR sdata$DdtdAbs) sdata$DdtdDuration = qpois(pct,lambda)
sdata$Ddtd MinDD
or sdata$Ddtd[sdata$Ddtd 0 sdata$VaR sdata$DdtdAbs]
sdata looks like this:
dataId date value Ddtd VaR
I suppose this doesn't work for the same reason as
sdata$VaR sdata$DdtdAbs sdata$DdtdDuration = 1
does only return FALSE and not a vector of TRUE and FALSE as
sdata$VaR sdata$DdtdAbs
would return.
Is there a ways around this?

Is the solution this simple?
sdata$VaR sdata$DdtdAbs sdata$DdtdDuration = 1

See ?:
'' and '' indicate logical AND and '|' and '||' indicate
Thx for the help, sorry I am just used to use from php and simply
assumed it would work identically.
