sims {rscc}

similarities

Description

sims and similarities both calculate for each pair of source code objects the similarity coefficients and return a data frame with the coefficients in descending order. A larger coefficient means a greater similarity.

Usage

sims(...)

similarities(
  docs,
  all = FALSE,
  coeff = c("jaccard", "braun", "dice", "hamann", "kappa", "kulczynski", "ochiai",
    "phi", "russelrao", "matching", "simpson", "sneath", "tanimoto", "yule")
)

Arguments

...

all parameters in sims are given to similarities

docs

document object

all

logical: should the similarity coefficients computed based on all sourcecode objects or just the two considered (default: FALSE)

coeff

character: coefficient to compute (default: "jaccard"), abbreviations can be used

Value

a data frame with the results
