Message-ID: <4507DBDC.3000204@bfro.uni-lj.si>

Hello,

I have looked once more into this issue and used options() approach with
(yet another :() option - humanReadable. This is the behaviour in R-devel.

> object.size(1000)
[1] 32
> c(object.size(1000), object.size(1:1000), object.size(1:1000000))
[1]      32    4024 4000024
> options(humanReadable=TRUE)
> object.size(1000)
[1] 32 B
> c(object.size(1000), object.size(1:1000), object.size(1:1000000))
[1] 32 B 4 kB 4 MB

I am not very satisfied with the class approach I have taken as a lot of
functions in R drop class attribute, say

> sort(c(object.size(1:1000), object.size(1000)) )
[1]   32 4024

Is it possible to bypass this without writing special methods for "byte"
class. I would appreciate any comments, suggestion. Thanks!

Dear R-core,

My friend and I have written a function to convert byte size into human
readable format as can be done with -h argument in say ls, df or du
shell commands. I have also tried to wrap it with print method with
object.size. Is there any intereset to include such a function into say
utils package? Any additional comments, suggestions are more than welcome.

Function and its man page can be found at
