[R] ts.union and tsp

[Dieter Menne]

I don't understand the following behavior of ccf

library(ts)
a<-runif(100)
b<-runif(100)

acf(a) # works
ccf(a,b) # fails

#.. because of the following 
ts.union(a,b)

# which fails on tsp(x) in .cbind.ts 
#tsser <- sapply(sers, function(x) length(tsp(x)) > 0)
