create reid-format data from raw and anon data frame

Usage

join_raw_anon_data(raw, anon, raw_header = "RAW_", anon_header = "ANON_")

Arguments

raw: raw data frame
anon: anonymized data frame
raw_header: strings which is added for columns from raw data
anon_header: strings which is added for columns from anon data

Value

a data frame: the cross join (every RAW row paired with every ANON row) of `raw` and `anon`, with their column names prefixed by `raw_header`/`anon_header` respectively.

Examples

raw  <- data.frame(ROW_NUMBER = 1:3, V = c(10, 20, 30))
anon <- data.frame(ROW_NUMBER = 1:3, V = c(11, 19, 32))

# every RAW row is paired with every ANON row: 3 x 3 = 9 candidate pairs.
# This is the shape the score_*() / reid_by_*() functions expect.
d <- join_raw_anon_data(raw, anon)
dim(d)
#> [1] 9 4
head(d, 3)
#>   RAW_ROW_NUMBER RAW_V ANON_ROW_NUMBER ANON_V
#> 1              1    10               1     11
#> 2              2    20               1     11
#> 3              3    30               1     11
