RaschSampler (version 0.8.0)

rstats: Calculating Statistics for the Sampled Matrices

Description

This function is used to calculate user defined statistics for the (original and) sampled matrices. A user defined function has to be provided.

Usage

rstats(RSobj, userfunc)

Arguments

RSobj

object as obtained from using rsampler or rsextrobj

userfunc

a user defined function which performs operations on the (original and) sampled matrices. The user function can only have an object of type matrix as input.

Value

• A list of objects as specified in the user supplied function

Examples

ctr <- rsctrl(burn_in = 10, n_eff = 5, step=10, seed = 12345678, tfixed = FALSE)
mat <- matrix(sample(c(0,1), 50, replace = TRUE), nr = 10)
rso <- rsampler(mat, ctr)
rso_st <- rstats(rso,phi)
unlist(rso_st)

# extract the third generated matrix
# (here, the first is the input matrix)
# and decode it into rsmat

rso2 <- rsextrobj(rso,4,4)
summary(rso2)
rsmat <- rstats(rso2, function(x) m<-matrix(x, nr = rso2$n) )
print(rsmat)

# apply a user function to the decoded object
print(phi(rsmat[[1]]))
