A function which extracts the asymptotic standard deviation for the
postive call proportion, R_m/m, under the selected FDP control method
from the supplied pwr
object, which is the result of a call to
the main function, pwrFDR.

The siginificant call proportion (SCP), R_m/m, under the selected FDP control method, is directly related to the ensemble power, which in turn, is determined by the effect size for tests distributed under the alternative, the sample size, the proportion of tests which are distributed according to the alternative and the size, alpha, in the selected FDP control method. Its asymptotic standard error, e.g. the asymptotic standard deviation over the square root of the number of simultaneous tests, m, gives an indication of the range of values one can expect for the significant call proportion. The standard deviations of the ratios R_m/m, T_m/M_m, and V_m/R_m are used internally in control of the distribution of V_m/R_m for the BHCLT FDP control method, and in calculation of the tail probability power for T_m/M_m.
Returns the asymptotic standard deviation of the significant call proportion, sd[R_m/m], as an un-named numeric.
