surv.curv: survival curves

In matsukik/RTsurvival: Survival Analaysis and Divergence Point Estimation Methods for Reaction Time Data

Description

Cacluate survival proportion of Reaction Time (RT) data in each bin

Usage

surv.curv(x, .bin, sample = FALSE, sample.n = length(x), replace = TRUE)

Arguments

x	A numeric vector of RT data.
.bin	A numeric vector specifying upper bounds of each timing bin
sample	logical. If TRUE, random sample of x is used to calculate survival proportion.
sample.n	A size of the sample when sample=TURE. Default to length(x)
replace	logical. If TRUE, sampling (in case of sample=TURE) will be with replacement.

Details

This funciton is used internally to calculate the survival proportion.

Value

A vector of length length(.bin) corresponding to survival proportion at each of timing bin in .bin.

Examples

#generate a random RT data
set.seed(1)
sbj.x <- rnorm(n = 50, mean=300, sd=50)

#obtain a survival curve for 600 bins form 0 ms to 600 ms.
curv.x <- surv.curv(sbj.x, .bin=seq(0,600,by=1))

#plot
plot(curv.x)
