Title Calculate attack rate from basic reproduction number

R02AR(R0, tol = 0.01)

`R0` |
a value or vector of values representing the basic reproduction number, must be >=0 |

`tol` |
a single >=0 value giving the tolerance for the calculated attack rate |

AR, the attack rate, calculated using the relationship: R0 = -log(1-AR)/AR

## Calculate the attack rate for a specific value of the reproduction number R02AR(2) # returns the AR for an R0 of 2 ## plot the relationship between R0 and attack rate x <- seq(1.01, 5, 0.01) plot(x, R02AR(x), type = "l", xlab = "R0", ylab = "Attack rate")
