The as.xts() function currently returns an object with a POSIXct index, unless you specify otherwise via the dateFormat argument.
library(xts)
data(sample_matrix)
p <- as.xts(sample_matrix)
d <- as.xts(sample_matrix, dateFormat = "Date")
This can be confusing to users who expect to be able to do things like this without issue:
d <- head(as.xts(sample_matrix, dateFormat = "Date"))
r <- as.xts(t(apply(d, 1, rank)))
merge(r, d)
merge(d, r)
It doesn't seem completely unreasonable for as.xts to return an object with a Date index, so that r could be easily merged with d. (The fact that merge(r, d) and merge(d, r) return different results is discussed in #191.)
