New features
- New arguments in ggsurvplot for changing font style, size and color of main title, axis labels, axis tick labels and legend labels: font.main, font.x, font.y, font.tickslab, font.legend.
- New arguments risk.table.title, risk.table.fontsize in ggsurvplot
- New argument risk.table.y.text.col: logical value. Default value is FALSE. If TRUE, risk table tick labels will be colored by strata (@MarcinKosinski, #8).
print.ggsurvplot() function added: S3 method for class 'ggsurvplot'.- ggsurvplot returns an object of class ggsurvplot which is list containing two ggplot objects:
- plot: the survival plot
- table: the number at risk table per time
- It's now possible to customize the output survival plot and the risk table returned by ggsurvplot, and to print again the final plot. (@MarcinKosinski, #2):
# Fit survival curves
#++++++++++++++++++++++++++++++++++++
require("survival")
fit<- survfit(Surv(time, status) ~ sex, data = lung)
# visualize
#++++++++++++++++++++++++++++++++++++
require(survminer)
ggsurvplot(fit, pval = TRUE, conf.int = TRUE,
risk.table = TRUE)
# Customize the output and then print
#++++++++++++++++++++++++++++++++++++
res <- ggsurvplot(fit, pval = TRUE, conf.int = TRUE,
risk.table = TRUE)
res$table <- res$table + theme(axis.line = element_blank())
res$plot <- res$plot + labs(title = "Survival Curves")
print(res)Minor changes
- p < 0.0001 is used (when pvalue < 0.0001).
Bug fixes
- ggtheme now affects risk.table (@MarcinKosinski, #1)
- xlim changed to cartesian coordinates mode (@MarcinKosinski, #4). The Cartesian coordinate system is the most common type of coordinate system. It will zoom the plot (like you’re looking at it with a magnifying glass), without clipping the data.
- Risk table and survival curves have now the same color and the same order
- Plot width is no longer too small when legend position = "left" (@MarcinKosinski, #7).
