RobinCar2 0.2.1

Now multiple stratification variables are supported in robin_surv by adding them on the right-hand side of the treatment formula.

There will be no more spurious warnings in robin_surv during the hazard ratio estimation coming from the variance calculation: Now the variance is only calculated after the hazard ratio estimate is obtained.
When adjusting for a single factor covariate, or when the covariate is strongly correlated with a strata variable in robin_surv, the function now works correctly and does not fail with a “singular design matrix” error any longer.
Fixed a bug in covariate-adjusted survival function estimation in robin_surv which could occur when there are character covariates with values only appearing in one treatment group, which could have led to incorrect results.

RobinCar2 0.2.0

Add survival analysis with log-rank test and hazard ratio estimation.
Add log_odds_ratio and log_risk_ratio function for inference.
Add contrast_mat to treatment_effect object.
Add confint to obtain confidence interval for prediction_cf and treatment_effect object.

Previously in robin_glm, vcovG is always used regardless the variance type argument. This is fixed now.
