WebCount the observations in each group Source: R/count-tally.R count () lets you quickly count the unique values of one or more variables: df %>% count (a, b) is roughly equivalent to df %>% group_by (a, b) %>% summarise (n = n ()) . count () is paired with tally (), a lower-level helper that is equivalent to df %>% summarise (n = n ()). Web[How do you predict the genotypes and phenotypes of the next generation?] In this example, the frequency of the survival-promoting B allele rose from 0.3 0.3 to 0.4 0.4 in a single generation. The percent of the population with the survival-promoting brown phenotype also rose from 50\% 50% to 65\% 65%.
