In line rendering of dates using 'chron' objects fails

[sanfordweisberg]

The following chunk correctly returns the date corresponding to d1 and to d1 + 180:

library(chron)
d1 <- chron("9/9/2013")
print(d1)
d1+180

The following in-line statements fail immediately following this chuck fails:
r d1 substitutes as.numeric(d1) = 15957 rather than "09/09/13"
r d1 + 180 substitutes as.numeric(d1 + 180) = 16137 rather than d1 + 180 = "03/09/14"

Should be fixed in the development version now. Thanks!
