sdc_*()functions now contain options and settings in a much better structure. Before, it was a bunch of strings which could be pasted together. Now, it's a list holding only the relevant values. The print output remained almost identical (minor improvements) due to new print methods.
sdc_*()functions is now conditional so that it's only called when
datais not a
data.tableyet. This can save memory and improve performance.
sdc_model()gained the new argument
source()), which allows new use cases. Thanks to Pantelis Karapanagiotis for the PR!
sdc_model()no longer returns wrong results for
felmmodels when the
id_varis used for clustering.
sdc_extreme()now only accepts character input. This makes the code more robust and easier to maintain.
sdc_modelis simplified (
sdc_extreme()now return the number of distinct ID's (instead of number of observations) used to calculate the extreme values
sdc_model()now checks if
datawas actually used to create
model(this only works if
modelhas a suitable S3 method for
id_varnow takes the default value of
getOption("sdc.id_var")in all functions, which makes it possible to use
options(sdc.id_var = "id")at the top of a script and save some typing
check_dominance()(and therefore in
check_dominance()now handles negative values correctly (as
