Convert data.table to csfmt_rts_data_v1 (deprecated)

Description

set_csfmt_rts_data_v1 converts a data.table to csfmt_rts_data_v1 by reference. csfmt_rts_data_v1 creates a new csfmt_rts_data_v1 (not by reference) from either a data.table or data.frame.

Usage

set_csfmt_rts_data_v1(x, create_unified_columns = TRUE, heal = TRUE)

csfmt_rts_data_v1(x, create_unified_columns = TRUE, heal = TRUE)

Arguments

x	The data.table to be converted to csfmt_rts_data_v1
create_unified_columns	Do you want it to create unified columns?
heal	Do you want to impute missing values on creation?

Value

An extended data.table, which has been modified by reference and returned (invisibly).

No return value, called for side effect of replacing the current data.table with a csfmt_rts_data_v1 in place.

Returns a duplicated csfmt_rts_data_v1.

Smart assignment

csfmt_rts_data_v1 contains the smart assignment feature for time and geography.

When the variables in bold are assigned using ⁠:=⁠, the listed variables will be automatically imputed.
