Arguments

sfit

a svykm object

xlabs

x-axis label, Default: 'Time-to-event'

ylabs

y-axis label.

xlims

numeric: list of min and max for x-axis. Default: NULL

ylims

numeric: list of min and max for y-axis. Default: c(0, 1)

ystratalabs

character list. A list of names for each strata. Default: NULL

ystrataname

The legend name. Default: 'Strata'

surv.scale

scale transformation of survival curves. Allowed values are "default" or "percent".

timeby

numeric: control the granularity along the time-axis; defaults to 7 time-points.

main

plot title, Default: ''

pval

logical: add the pvalue to the plot?, Default: FALSE

pval.size

numeric value specifying the p-value text size. Default is 5.

pval.coord

numeric vector, of length 2, specifying the x and y coordinates of the p-value. Default values are NULL

pval.testname

logical: add '(Log-rank)' text to p-value. Default = F

legend

logical. should a legend be added to the plot? Default: TRUE

legendposition

numeric. x, y position of the legend if plotted. Default: c(0.85, 0.8)

ci

logical. Should confidence intervals be plotted. Default = NULL

linecols

Character. Colour brewer pallettes too colour lines. Default: 'Set1', "black" for black with dashed line.

dashed

logical. Should a variety of linetypes be used to identify lines. Default: FALSE

cumhaz

Show cumulaive incidence function, Default: F

design

Data design for reactive design data , Default: NULL

subs

= NULL,

table

logical: Create a table graphic below the K-M plot, indicating at-risk numbers?

label.nrisk

Numbers at risk label. Default = "Numbers at risk"

size.label.nrisk

Font size of label.nrisk. Default = 10

cut.landmark

cut-off for landmark analysis, Default = NULL

showpercent

Shows the percentages on the right side.
