[R] I have a problem with the log2 function

[Frank Mattes]

Dear R users,

according the help(log), the function
log2(x) should give the natural logarithm of x.

I expect in case of x=2 to to get 0.6931, however, R gives me 1 as a result.

Similar, logb(2,2) gives 1 again.

I'm wondering if I have missed something ?

Yours
Frank
