Spaircomp: Pairwise Comparisons of Survival Tests for One-Way Layout

Description

Spaircomp is a generic function for pairwise comparisons of survival tests in one-way layout by adjusting p-values.

Usage

# S3 method for survtests
Spaircomp(x, adjust.method = c("bonferroni", "holm", "hochberg", "hommel", "BH", 
  "BY", "fdr", "none"), verbose = TRUE, ...)

Value

Returns a data.frame of output.

Arguments

x

a survtests object.

adjust.method

Method for adjusting p values (see p.adjust). Default is set to "bonferroni".

verbose

a logical for printing output to R console.

...

Examples

library(survival)
lung$status <- ifelse(lung$status == 2, 1, 0)
lung$age <- arules::discretize(lung$age, breaks = 3, labels = c("Low","Medium","High"))

library(SurvivalTests)
# \donttest{
out = SANOVA(time~age+status, lung, alpha = 0.05)

Spaircomp(out, adjust.method = "bonferroni")


# to illustrate pairwise comparison, alpha is set to 0.5
out2 = SANOVA(time~age+status, lung, alpha = 0.5)

Spaircomp(out2, adjust.method = "bonferroni")

Spaircomp(out2, adjust.method = "hochberg")

Spaircomp(out2, adjust.method = "hommel")

Spaircomp(out2, adjust.method = "holm")
# }
