# Create a minimal data frame with the required columns
df <- data.frame(lifetime = 1:2, risk_set = c(.8, .20),
                 hazard = c(0.1, 0.125), se_log_hazard = c(0.1, 0.1),
                 lower_ci = c(0.08, 0.1), upper_ci = c(0.12, 0.15))

# Construct the alife object
my_alife_obj <- new_alife(df)
class(my_alife_obj)
