This is a function to conveniently and quickly compute the absolute relative risk (ARR) and its confidence interval.
arr( expPos, expN, conPos, conN, conf.level = 0.95, digits = 2, printAsPercentage = TRUE ) # S3 method for ufsARR print(x, digits = x$digits, printAsPercentage = x$printAsPercentage, ...)
| expPos | Number of positive events in the experimental condition. |
|---|---|
| expN | Total number of cases in the experimental condition. |
| conPos | Number of positive events in the control condition. |
| conN | Total number of cases in the control condition. |
| conf.level | The confidence level for the confidence interval. |
| digits | The number of digits to round to when printing the results. |
| printAsPercentage | Whether to multiply with 100 when printing the results. |
| x | The result of the call to |
| ... | Any additional arguments are neglected. |
An object with in estimate, the ARR, and in conf.int, the
confidence interval.
