The surname data comes from the United States Census. The first name data comes from Tzioumis (2018, <dx.doi.org/10.1038/sdata.2018.25>)

predict_race(name, probability = TRUE, surname = TRUE)

name | String or vector of strings of surname or first name that you want to know the race of. |
---|---|

probability | If TRUE (default) will provide columns for each race with the probability that the surname is of that race. If FALSE, will only return the name, the match-name from the Census data, and the most likely race. |

surname | If TRUE (default) will return the race based on the inputted name being a surname. If FALSE, will return the race based on the inputted name being a first name. |

A data.frame with three or nine columns: The first column has the name as inputted, the second column has the cleaned up name (no spaces or punctuation, all lowercase), the third column tells the likely race of the surname or first name (if there are multiple races with the same probability of a match, it will be a string with each race separated by a comma). If the parameter probability is false, these three columns are all that is returned. Otherwise, columns 4-9 tell the specific probability that the surname or first name is each race.
