This package attempts to replicate the features of the Stata command bcstats in R.
Using the R package devtools, you can easily install bcstatsR.
devtools::install_github('vikjam/bcstatsR')
# Load bcstatsR
library(bcstatsR)
# Load a toy example bundled with bcstatsR
data(survey, bc)
# Compare the differences with bcstats
compute.bc <- bcstats(surveydata = survey,
bcdata = bc,
id = "id",
t1vars = "gender",
t2vars = "gameresult",
t3vars = "itemssold",
enumerator = "enum",
ttest = "itemssold")
print(compute.bc$backcheck)
You should see a list of all the differences
