sometimes censoring weight columns have names

[topepo]

Discovered in tidymodels/extratests#120

Only when a single row is predicted at a single time:

library(tidymodels)
library(censored)
#> Loading required package: survival

tidymodels_prefer()
theme_set(theme_bw())
options(pillar.advice = FALSE, pillar.min_title_chars = Inf)

set.seed(1)
sim_dat <- prodlim::SimSurv(500) %>%
  mutate(event_time = Surv(time, event)) %>%
  select(event_time, X1, X2)

parsnip_fit <- 
  proportional_hazards() %>% 
  fit(event_time ~ ., sim_dat)

## 

times <- c(2.0, 1.0)

##

res_2_times_2_rows <- 
  augment(parsnip_fit, new_data = head(sim_dat, 2), eval_time = times)
names(res_2_times_2_rows$.pred[[1]]$.weight_censored)
#> NULL

res_2_time_1_row <- 
  augment(parsnip_fit, new_data = head(sim_dat, 1), eval_time = times)
names(res_2_time_1_row$.pred[[1]]$.weight_censored)
#> NULL

res_1_time_2_row <- 
  augment(parsnip_fit, new_data = head(sim_dat, 2), eval_time = times[1])
names(res_1_time_2_row$.pred[[1]]$.weight_censored)
#> NULL

res_1_time_1_row <- 
  augment(parsnip_fit, new_data = head(sim_dat, 1), eval_time = times[1])
names(res_1_time_1_row$.pred[[1]]$.weight_censored)
#> [1] "time"
