[R] Hex Decimal Convert

[John Fox]

Dear Edwin,

There's a distinction between the way in which a number is stored
internally and the way in which it's printed. R is reading the hex
numbers correctly but is printing them in decimal. You can assign the
class "hexmode" to the vector containing the data and then it will
print in hex:

> data <- c(6565, 0x47780439, 0x00000000, 0x00000000, 0)
> data
[1]       6565 1199047737          0          0          0
> class(data) <- "hexmode"
> data
[1] "000019a5" "47780439" "00000000" "00000000" "00000000"

Notice that the whole vector is printed in hex. If you don't want that,
then you could put the data into a list with some members of class
"hexmode" and others not.

I hope this helps,
 John
