The error is in printing ...
foo <- data.frame(I(z))
works. It is not hard to create a data frame you cannot print, and this
is one. It could be considered a bug in format.AsIs, which calls
toString without removing its class.
Traceback() helps:
14: format.AsIs(x, ...)
13: format(x, ...)
12: as.character.POSIXt(1199386325.312)
11: as.character(1199386325.312)
10: paste(x, collapse = ", ")
9: toString.default(x[[i]], width = width, ...)
8: toString(x[[i]], width = width, ...)
7: format.AsIs(x[[i]], ..., justify = justify)
6: format(x[[i]], ..., justify = justify)
5: format.data.frame(x, digits = digits, na.encode = FALSE)
4: as.matrix(format.data.frame(x, digits = digits, na.encode = FALSE))
3: print(as.matrix(format.data.frame(x, digits = digits, na.encode =
FALSE)),
..., quote = quote, right = right)
2: print.data.frame(list(z = c(1199386325.312, 1199386325.312,
1199386325.312,
1199386325.312, 1199386325.312)))
1: print(list(z = c(1199386325.312, 1199386325.312, 1199386325.312,
1199386325.312, 1199386325.312)))
