# NOT RUN {
## Write to tempdir() and clean afterwards
f <- file.path(tempdir(), "itempool_science.csv")
write.csv(itempool_science_raw, f, row.names = FALSE)
itempool_science <- loadItemPool(f)
file.remove(f)

f <- file.path(tempdir(), "itemattrib_science.csv")
write.csv(itemattrib_science_raw, f, row.names = FALSE)
itemattrib_science <- loadItemAttrib(f, itempool_science)
file.remove(f)
