survminer 0.2.2

New features

• New ggcoxdiagnostics function that plots diagnostic graphs for Cox Proportional Hazards model ([@MarcinKosinski, #16](https://github.com/kassambara/survminer/issues/16)).
• Vignette added: Survival plots have never been so informative ([@MarcinKosinski, #39](https://github.com/kassambara/survminer/issues/39))
• New argument linetype in 'ggsurvplot' ([@MarcinKosinski, #45](https://github.com/kassambara/survminer/issues/45)). Allowed values includes i) "strata" for changing linetypes by strata (i.e. groups); ii) a numeric vector (e.g., c(1, 2)) or a character vector c("solid", "dashed").

Bug fixes

• lienetype argument changed to linetype in ggsurvplot() documentation. ([@ViniciusBRodrigues, #43](https://github.com/kassambara/survminer/issues/43))

survminer 0.2.1

New features

• New ggcoxzph function that displays a graph of the scaled Schoenfeld residuals, along with a smooth curve using 'ggplot2'. Wrapper around . ([@MarcinKosinski, #13](https://github.com/kassambara/survminer/issues/13))

• New ggcoxfunctional function that displays graphs of continuous explanatory variable against martingale residuals of null cox proportional hazards model, for each term in of the right side of input formula. This might help to properly choose the functional form of continuous variable in cox model, since fitted lines with lowess function should be linear to satisfy cox proportional hazards model assumptions. ([@MarcinKosinski, #14](https://github.com/kassambara/survminer/issues/14))

• New function theme_classic2: ggplot2 classic theme with axis line. This function replaces ggplot2::theme_classic, which does no longer display axis lines (since ggplot2 v2.1.0)

Minor changes

• post-customization of color and fill no longer shows warnings like "Scale for 'fill' is already present. Adding another scale for 'fill', which will replace the existing scale" ([@MarcinKosinski, #11](https://github.com/kassambara/survminer/issues/11)).
• now, post-customization of survival curve colors will automatically affect the risk table y axis text colors ([@MarcinKosinski, #11](https://github.com/kassambara/survminer/issues/12)).
• Default value for the argument risk.table.y.text.col is now TRUE.
• New argument risk.table.y.text for the function ggsurvplot. logical argument. Default is TRUE. If FALSE, risk table y axis tick labels will be hidden ([@MarcinKosinski, #28](https://github.com/kassambara/survminer/issues/28)).

Bug fixes

• Black dots removed from risk table ([@Feli-Anna, #25](https://github.com/kassambara/survminer/issues/25))

survminer 0.2.0

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](https://github.com/kassambara/survminer/issues/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](https://github.com/kassambara/survminer/issues/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](https://github.com/kassambara/survminer/issues/1))

• xlim changed to cartesian coordinates mode ([@MarcinKosinski, #4](https://github.com/kassambara/survminer/issues/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](https://github.com/kassambara/survminer/issues/7)).

survminer 0.1.1
