All options can be set with options(option.name = option.value). You
can get value of option with getOption("option.name").
expss.digits Number of digits after decimal separator which will be
shown for tables. This parameter is supported in the datatable,
htmlTable.etable and print methods. NULL is
default and means 1 digit. NA means no rounding.
expss.enable_value_labels_support By default, all labelled
variables will use labels as labels for factor levels when factor is
called. So any function which calls factor/as.factor will use
value labels. In details this option changes behavior of two methods for class
labelled - as.character and unique - on which
factor depends entirely. If you have compatibility problems set this
option to zero: options(expss.enable_value_labels_support = 0).
expss.output By default tables are printed in the
console. You can change this behavior by setting this option. There are three
possible values: 'rnotebook', 'viewer' or 'raw'. First
option is useful when you run your code in the R Notebook - output will be
rendered to nice HTML. The second option will render tables to RStudio
viewer. knitr is supported automatically via knit_print method.
Option raw disables any formatting and all tables are printed as
data.frames.
