To cite the hyper2 package in publications, please use @hankin2017_rmd. This minimal document reads file icons.txt and creates R objects icons, icons_matrix, and icons_maxp. The dataset is discussed extensively in @west2008 and @hankin2010.

icons_table  <- as.matrix(read.table("icons.txt",header=TRUE))
icons_table

Thus the first row shows that a total of $5+3+4+3=15$ respondents were shown icons NB, L, THC, and WAIS; 5 of them chose NB as "most concerning", 3 chose L, 4 chose THC and 3 chose WAIS.

We can use function saffy() to convert the table into a hyper2 object:

icons <- saffy(icons_table)
icons
icons_maxp <- maxp(icons)
icons_maxp

This file exists for consistency; an extended discussion (and statistical tests) are presented in the vignette icons.

Following lines create icons.rda, residing in the data/ directory of the package.

save(icons_table,icons,icons_maxp,file="icons.rda")
