lexample {ndl} | R Documentation |
Ten monomorphemic and inflected English words with fictive frequencies, and meanings.
data(lexample)
A data frame with 10 observations on the following 3 variables:
Word
A character vector specifying word forms
Frequency
A numeric vector with the – fictive – frequencies of occurrence of the words
Outcomes
A character vector specifying the meaning components of the words, separated by underscores
This example lexicon is used in Baayen et al. (2011) (table 8, figure 4) to illustrate the Rescorla-Wagner equations.
