david {flan}

Mutant counts and final numbers from H. L. David (1970)

Description

Samples from Table 1 and 2 of H. L. David (1970).

Classes have been replaced by medians, 1000 for the last class.

Usage

  data(david)

Format

A list of 11 lists named "D<index of the sample>". Each list includes :

• sample A sample of mutants counts.

• fn : the mean final numbers of cells, or a sample of final numbers (only for the last one).

The i-th sample of the list includes the i-th column of Table 1, except the last sample which includes Table 2.

Examples

# samples 1-10 only give mean final numbers
D1 <- david[[1]]; D1
# estimate mutation probability
mutestim(D1$mc,mfn=D1$mfn)

# sample 11 has individual final numbers
D11 <- david[[11]]; D11
# with mean final number
mutestim(D11$mc,mfn=mean(D11$fn))
# with true final numbers
mutestim(D11$mc,D11$fn)
