clustra (version 0.2.1)

clustra_rand: clustra_rand: Rand Index cluster evaluation

Description

Performs trajectories runs for several k and several random start replicates within k. Returns a data frame with a Rand Index comparison between all pairs of clusterings. This data frame is typically input to rand_plot to produce a heat map with the Adjusted Rand Index results.

Usage

clustra_rand(
  data,
  k,
  starts = "random",
  mccores = 1,
  replicates = 10,
  maxdf = 30,
  conv = c(10, 0),
  save = FALSE,
  verbose = FALSE
)

Value

See allpair_RandIndex.

Arguments

data

The data (see clustra description).

k

Vector of k values to try.

starts

See clustra.

mccores

Number of cores for replicate parallelism via mclapply.

replicates

Number of replicates for each k.

maxdf

Fitting parameters. See link{trajectories}.

conv

Fitting parameters. See link{trajectories}.

save

Logical. When TRUE, save all results as file results.Rdata.

verbose

Logical. When TRUE, information about each run of clustra (but not iterations within) is printed.
