surv_curv: multiple survival curves

In renlund/miscmatch: Miscellaneous Functions For Matching

Description

create multiple survival curves for multiple endpoints, stratifications and groupings

Usage

surv_curv(data, surv, strata = NULL, glist = NULL, w = NULL,
  prefix = c(event = "ev.", time = "t."), progress = FALSE,
  stringsAsFactors = TRUE)

Arguments

data	the data
surv	the Surv objects (as character, refering to variables in 'data') OR the common names of time + event, if these have similar names (differing only in perfix)
strata	stratifying variable
glist	a grouping list, or the name of a grouping variable in 'data'
w	weight or name of variable that provides weights
prefix	prefix values for times and events
progress	primitive displayer of progress
stringsAsFactors	logical, if TRUE will keep ordering of ingoing stuff

Value

A tbl_df with an rbinded broom::tidy'd survival::survfited version of all the combinations of 'strata' and 'glist' for each 'surv'. That is a crap explanation...

Examples

n = 1200
df <- data.frame(
        t.foo = abs(rnorm(n, 10, 2)),
        ev.foo = rbinom(n, 1, 0.2),
        t.bar = abs(rnorm(n, 10, 3)),
        ev.bar = rbinom(n, 1, 0.3),
        strutt = sample(letters[1:2], n, TRUE),
        gsak = sample(LETTERS[4:7], n, TRUE),
        wait = .5 + abs(rnorm(n, 0, 1))
)
surv_curv(data = df, surv = c("foo", "bar"), w = "wait",
          strata = "strutt", glist = "gsak")
