“Data for our third example were compiled by Margolin et al. (1981) from an Ames Salmonella reverse mutagenicity assay. Table 1 shows the number of revertant colonies observed on each of 3 replicate plates tested at each of 6 dose levels of quinoline.” (Breslow, 1984, Table 1).
A data frame with 18 observations on the following 2 variables.
a numeric vector: the dose level of quinoline (microgram per plate).
a numeric vector: the number of revertant colonies of TA98 Salmonella.
