• Fixed changable ALL group in ezcox_group().
• Supported interaction term in controls option.

library(survival)
library(ezcox)

lung$ph.ecog <- factor(lung$ph.ecog)
ezcox(lung, covariates = c("age"), controls = "sex:ph.ecog")
ezcox(lung, covariates = c("age", "wt.loss"), controls = "sex:ph.ecog")

show_forest(lung, covariates = c("age", "wt.loss"), controls = "sex:ph.ecog")

lung2 <- lung
lung2$sex <- ifelse(lung2$sex == 1, "M", "F")
ezcox_group(lung2, grp_var = "sex", covariate = "ph.ecog", controls = "age : wt.loss")

ezcox 1.0.1

• Fixed sample counting when input data contains unavailable time and status values.
• A vignette for advanced usage has been added to https://shixiangwang.github.io/ezcox-adv-usage/.
• Fixed label rendering for global p value.

ezcox 1.0.0

• Added forester().
• Used roxytest for unit testing.

ezcox 0.8.2

• Added code to panel function to support new feature from forest_model().

library(survival)
library(ezcox)

lung$ph.ecog <- factor(lung$ph.ecog)
# Build unvariable models
# and show global p value for each model
# aside the 'reference' label.
show_forest(lung, covariates = c("age", "sex", "ph.ecog"), show_global_p = "aside")
