mutantfreq {GLMsData}

Cell mutant frequencies in children

Description

The “somatic cell mutant frequencies at the hprt locus of the X-chromosome” in healthy children

Usage

data(mutantfreq)

Format

A data frame with 49 observations on the following 5 variables.

Donor

the donor identifier; a factor

Sex

the sex of the child; a factor with levels F (females) or M (males)

Age

the age of the child in completed years; a numeric vector

Ceff

the mean unselected cloning efficiency; a numeric vector

Mfreq

the mutant frequencies \times 10^{-6}; a numeric vector

Details

In the original paper, the children are sometimes referred to as belonging to Group II (Ages 0 to 5), Group III (Ages 6 to 11) or Group IV (Ages 12 to 17). (Group I refers to cord data referenced to another article.) Age may be treated as categorical with these categories.
