density.dmc: Calculate Probability Density for an Experimental Condition

Description

A S3 method derived from stats density to get probability density for a specified experimental condition. The user has to indicate a correctness column.

Usage

# S3 method for dmc
density(x, C = NA, ...)

Arguments

x

a data.cell as a data frame as welle dmc class, containing only one experimental condition.

C

a string, e.g., "r1" or a logical vector to represent the correctness column in a data frame

...

other arguments

Examples

model <- model.dmc(
 p.map     = list(a="1",v="1",z="1",d="1",sz="1",sv="1", t0="1",st0="1"),
 constants = c(st0=0,d=0),
 match.map = list(M=list(s1="r1",s2="r2")),
 factors   = list(S=c("s1","s2")),
 responses = c("r1","r2"),
 type      = "rd")

pVec <- c(a=1,v=1, z=0.5, sz=0.25, sv=0.2,t0=.15)
dat1 <- simulate(model, nsim=1e2, p.vector=pVec)
mdi1 <- data.model.dmc(dat1, model)
censored.s1  <- censor(mdi1[mdi1$S=="s1", ], xlim=c(.2, 3))
s1r1.density <- density(censored.s1, C="r1")
