Hi,
I wanted to print a big integer value in hexadecimal format with sprintf() but could not (cf. here
after). As R supports integer values upto 2**53-1 (storing them in a double) is it possible to make
sprintf() to work on such big values?
Best,
Serguei.

Error in sprintf("%x", 2^31) :
invalid format '%x'; use format %f, %e, %g or %a for numeric objects
