[R] dec2bin?

[Tuszynski, Jaroslaw W.]

It is unclear what you are trying to do, but check bin2raw in caTools
package:

>  print(x <- (1:5)*pi)      
[1]  3.141593  6.283185  9.424778 12.566371
[5] 15.707963
>         print(y <- bin2raw(x))
 [1] 18 2d 44 54 fb 21 09 40 18 2d 44 54 fb 21 19
[16] 40 d2 21 33 7f 7c d9 22 40 18 2d 44 54 fb 21
[31] 29 40 5e 38 55 29 7a 6a 2f 40
>         print(z <- raw2bin(y,"double"))
[1]  3.141593  6.283185  9.424778 12.566371
[5] 15.707963 


May be that is what you need.

Hello,

I just want to ask if there is any function that can convert decimal number
to binary vector.

Thanks a lot.
Haiyong
