Aggregate data

Use function transform_data() to convert line listing data (data with t, seropositive columns) to aggregated data (data with t, pos, tot columns)

Arguments:

  • t the time vector

  • spos the seropositive vector (TRUE/FALSE or 1/0)

linelisting_data <- hcv_be_2006
aggregated_data <- transform_data(linelisting_data$dur, linelisting_data$seropositive)
