[R] sapply and Date objects

[Gabor Grothendieck]

>From ?sapply we see that sapply requires a list or
atomic vector.   If its not a list then looking at the first
few two lines of sapply we see it tries to convert
the first arg to a list using as.list.  Note that using
your dt:

> as.list(dt)
[[1]]
[1] -5813

so try this instead:

sapply(list(dt), as.character)
