The goal of simplanonym is to easily anonymise individuals that appear in multiple datasets, in a consistent way.
Consistent anonymisation means that:
You can install the development version of simplanonym from GitHub with:
# install.packages("devtools")
devtools::install_github("dkgaraujo/simplanonym")This is a basic example which shows you how to solve a common problem:
library(simplanonym)
rand_tbl_1 <- vroom::gen_tbl(10, 4, col_types = "fffd")
rand_tbl_2 <- vroom::gen_tbl(10, 2, col_types = "fd")
rand_tbl_2$X3 <- rand_tbl_1$X3
# note:
# * rand_tbl_1 and rand_tbl_2 share three column names,
# of which X2 is a factor in one but not the other.
# * X1 factors do not overlap, but their anonymisation
# should still be consistent (ie, different levels should
# have their own unique anonymised factors).
# * For X3, the anonymised factors should consider the levels
# at both `rand_tbl_1$X3` and `rand_tbl_2$X3`.
data_list <- list(rand_tbl_1, rand_tbl_2)
