get.decluttered: Get decluttering matrix indicating where to show/hide reference lines

Description

Declutter TCATA curves by hiding reference lines from plots showing TCATA curves.

Usage

get.decluttered(x = x, n.x = n.x, y = y, n.y = n.y, alpha = 0.05)

Value

declutter vector in which 1 indicates "show" and NA indicates "hide"

Arguments

x: selections for sample of interest (can be a vector if several samples of interest)
n.x: evaluations of x (can be a vector if several samples of interest)
y: selections for comparison (can be a vector if several comparisons will be made)
n.y: evaluations of y (can be a vector if several comparisons of interest)
alpha: significance level

Run this code


# functionality of get.decluttered() is conveniently provided in citation.counts()

# Data set: ojtcata
# Get declutter matrix for comparison of Product 2 vs. average of all products
data(ojtcata)
oj2.v.all <- citation.counts(ojtcata, product.name = "2", product.col = 2,
       attribute.col = 4, results.col = 5:25, comparison = "average")
oj2.v.all$declutter

# same as

p2.declutter <- get.decluttered(x = c(oj2.v.all$P1), n.x = oj2.v.all$Pn,
                                y = c(oj2.v.all$C1), n.y = oj2.v.all$Cn)
