epiR: Epidemiological Analysis Tools for Disease Frequency and Surveillance

Mark A. Stevenson's epiR provides tools for analyzing epidemiological and surveillance data. The package contains functions for adjusting measures of disease frequency, quantifying measures of association from contingency tables, and computing confidence intervals for incidence risk and rate estimates. It also supports sample size calculations for cross-sectional, case-control, and cohort studies, as well as functions for freedom surveys and scenario tree modelling.

Use Cases

• Directly and indirectly adjust disease frequency measures based on the described statistical functions.
• Calculate sample sizes for cross-sectional, case-control, and cohort studies using the provided methods.
• Estimate surveillance system sensitivity for freedom-from-disease surveys as mentioned in the description.
• Perform scenario tree modelling analyses for risk assessment as supported by the tools.

Strengths

• Provides a specialized suite of functions for epidemiological and surveillance data analysis.
• Includes tools for both study design (sample size calculation) and data analysis (confidence intervals, measures of association).

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
