Hi there and a happy new year!
I've got a question regarding the VaR-function from the
PerformanceAnalytics-package. When I call it in order to compute VaR
contributions using the nonparametric kernel estimator, I get an error
report. Obviously this is independent of my data, because I can
replicate it using the edhec example data, as shown below. Does anybody
have a hint how to deal with this problem?
Cheers,
Gero
###
library(PerformanceAnalytics)
data(edhec)
VaR(R=edhec, method="kernel", portfolio_method = "component")

> VaR(R=edhec, method="kernel", portfolio_method = "component")
no weights passed in, assuming equal weighted portfolio
Fehler in `colnames<-`(`*tmp*`, value = c("Convertible Arbitrage", "CTA
Global", :
attempt to set colnames on object with less than two dimensions

Looks like a bug, I can replicate it here. Not sure what's broken yet, as this all had to work when we sent it to CRAN recently. We'll debug and patch. ES is broken too with method='kernel' Regards, - Brian
