long_to_sequences: Convert Long Format to Sequences

Description

This function converts a data frame in long format into sequences by combining all rows with the same sequence identifier. It also aggregates covariates if provided.

Usage

long_to_sequences(
  sequences_long,
  elements = "element",
  sequence_identifier = "sequence_identifier",
  start_time = "start_time",
  end_time = "end_time",
  covariates = NULL
)

Value

A data frame with sequences, start time, end time, and aggregated covariates.

Arguments

sequences_long

A data frame in long format containing the sequences.

elements

Column name for elements that should be combined into sequences.

sequence_identifier

Column name with the sequence identifier.

start_time

Column name with the start time.

end_time

Column name with the end time.

covariates

A vector with column names of the covariates. Defaults to NULL.

Examples

sequences_long <- data.frame(sequence_identifier = c(1, 1, 2, 2, 2),
                             element = c('A', 'B', 'A', 'B', 'C'),
                             start_time = c(1, 2, 1, 2, 3),
                             end_time = c(2, 3, 2, 3, 4),
                             covariate1 = c('X', 'Y', 'X', 'Y', 'Z'),
                             covariate2 = c('M', 'N', 'M', 'N', 'O'))
long_to_sequences(sequences_long,
                  elements = 'element',
                  sequence_identifier = 'sequence_identifier',
                  start_time = 'start_time',
                  covariates = c('covariate1', 'covariate2'))
