_D_e_s_c_r_i_p_t_i_o_n:
‘log’ computes logarithms, by default natural logarithms, ‘log10’
computes common (i.e., base 10) logarithms, and ‘log2’ computes
binary (i.e., base 2) logarithms. The general form ‘log(x, base)’
computes logarithms with base ‘base’.
‘log1p(x)’ computes log(1+x) accurately also for |x| << 1.
‘exp’ computes the exponential function.
‘expm1(x)’ computes exp(x) - 1 accurately also for |x| << 1.
_U_s_a_g_e:
log(x, base = exp(1))
logb(x, base = exp(1))
log10(x)
log2(x)
log1p(x)
exp(x)
expm1(x)
_A_r_g_u_m_e_n_t_s:
x: a numeric or complex vector.
base: a positive or complex number: the base with respect to which
logarithms are computed. Defaults to e=‘exp(1)’.
_D_e_t_a_i_l_s:
All except ‘logb’ are generic functions: methods can be defined
for them individually or via the ‘Math’ group generic.
‘log10’ and ‘log2’ are only convenience wrappers, but logs to
bases 10 and 2 (whether computed _via_ ‘log’ or the wrappers) will
be computed more efficiently and accurately where supported by the
OS. Methods can be set for them individually (and otherwise
methods for ‘log’ will be used).
‘logb’ is a wrapper for ‘log’ for compatibility with S. If (S3 or
S4) methods are set for ‘log’ they will be dispatched. Do not set
S4 methods on ‘logb’ itself.
All except ‘log’ are primitive functions.
_V_a_l_u_e:
A vector of the same length as ‘x’ containing the transformed
values. ‘log(0)’ gives ‘-Inf’, and ‘log(x)’ for negative values
of ‘x’ is ‘NaN’. ‘exp(-Inf)’ is ‘0’.
For complex inputs to the log functions, the value is a complex
number with imaginary part in the range [-pi, pi]: which end of
the range is used might be platform-specific.
_S_4 _m_e_t_h_o_d_s:
‘exp’, ‘expm1’, ‘log’, ‘log10’, ‘log2’ and ‘log1p’ are S4 generic
and are members of the ‘Math’ group generic.
Note that this means that the S4 generic for ‘log’ has a signature
with only one argument, ‘x’, but that ‘base’ can be passed to
methods (but will not be used for method selection). On the other
hand, if you only set a method for the ‘Math’ group generic then
‘base’ argument of ‘log’ will be ignored for your class.
_S_o_u_r_c_e:
‘log1p’ and ‘expm1’ may be taken from the operating system, but if
not available there then they are based on the Fortran subroutine
‘dlnrel’ by W. Fullerton of Los Alamos Scientific Laboratory (see
<URL: http://www.netlib.org/slatec/fnlib/dlnrel.f>) and (for small
x) a single Newton step for the solution of ‘log1p(y) = x’
respectively.

Language_. Wadsworth & Brooks/Cole. (for ‘log’, ‘log10’ and
‘exp’.)
Chambers, J. M. (1998) _Programming with Data. A Guide to the S
Language_. Springer. (for ‘logb’.)
_S_e_e _A_l_s_o:
‘Trig’, ‘sqrt’, ‘Arithmetic’.
_E_x_a_m_p_l_e_s:
log(exp(3))
log10(1e7) # = 7

_D_e_s_c_r_i_p_t_i_o_n:
‘abs(x)’ computes the absolute value of x, ‘sqrt(x)’ computes the
(principal) square root of x, sqrt{x}.
The naming follows the standard for computer languages such as C
or Fortran.
_U_s_a_g_e:
abs(x)
sqrt(x)
_A_r_g_u_m_e_n_t_s:
x: a numeric or ‘complex’ vector or array.
_D_e_t_a_i_l_s:
These are internal generic primitive functions: methods can be
defined for them individually or via the ‘Math’ group generic.
For complex arguments (and the default method), ‘z’, ‘abs(z) ==
Mod(z)’ and ‘sqrt(z) == z^0.5’.
‘abs(x)’ returns an ‘integer’ vector when ‘x’ is ‘integer’ or
‘logical’.
_S_4 _m_e_t_h_o_d_s:
Both are S4 generic and members of the ���Math’ group generic.
_R_e_f_e_r_e_n_c_e_s:

Language_. Wadsworth & Brooks/Cole.
_S_e_e _A_l_s_o:
‘Arithmetic’ for simple, ‘log’ for logarithmic, ‘sin’ for
trigonometric, and ‘Special’ for special mathematical functions.
‘plotmath’ for the use of ‘sqrt’ in plot annotation.
_E_x_a_m_p_l_e_s:
require(stats) # for spline
