Hello,
I'm trying to write a function which, among other things, attempts to
convert variables of type 'character' into various other classes like
'integer', 'numeric', 'character' & "Date", depending on the class of
a second parameter to this same function. Converting from character
to Date is no problem with the "as.Date" function:
> date.var.char <- as.character("2009-10-21")
> as.Date(date.var.char)
[1] "2010-02-23"
But when I try to do the equivalent using just "as" I get an error
> date.var.Date <- as.Date("2009-10-21")
> as(date.var.char, class(date.var.Date))
Error in as("2009-10-21", "Date"): no method or default for coercing
"character" to "Date"
The same is true for POSIXt, POSIXlt, & POSIXct
Is there something that I can do without writing those extra 2 lines
of code to check and see if 'date.var.Date' is actually of the 'Date'
class? Or is this a bug?
Thanks,
Dave
