custom_exposure: Pull exposure series from data set

In eesim: Simulate and Evaluate Time Series for Environmental Epidemiology

Description

Example of a custom exposure function that can be passed to eesim or power_calc. By default, this function pulls exposure data from the Chicago NMMAPS data set in the dlnm package. The user may specify a different data set from which to pull exposure values.

Usage

custom_exposure(n, df = dlnm::chicagoNMMAPS, metric = "temp",
  start.date = NULL)

Arguments

n	A numeric value specifying the number of days for which to obtain an exposure value.
df	Data frame from which to pull exposure values.
metric	A character string specifying the desired exposure metric. Options are: "temp" "dptp" "rhum" "pm10" "o3" (Note: These are the column names for exposure measurements in the observed data.)
start.date	A date of the format "yyyy-mm-dd" from which to begin pulling exposure values. Dates in the Chicago NMMAPS data set are from 1987-01-01 to 2000-12-31.

Value

A numeric vector of length n giving exposure values.

Examples

custom_exposure(n = 5, metric = "temp", start.date = "2000-01-01")
