aggregate_sequences | R Documentation |
A dataframe having id, date and event column can be aggregated using this function
aggregate_sequences(unaggregated_data, format = "%m-%d-%Y", index_date = FALSE, calendar = FALSE, unit = "week", n_units = 1, anchor_table = NA, anchor_vector = NA, base_date = NA, occurence = min, multiset = FALSE, include_date = FALSE, summary_stats = TRUE, output_directory = "~")
unaggregated_data |
A dataframe that has exactly 3 columns in this order - id, date, event |
format |
String specifying format of the date |
index_date |
Logical indicator which indicates if the data is in a numerical format which represents the number of days since an index event, i.e. 0 represents first date, 1 respresents 1 day since index date (0), 2 represents 2 days since index date (0), etc. |
calendar |
Boolean indicating whether or not to use calendar aggregation. Defaults to false |
unit |
String specifying unit of aggregation. Takes one of c("day", "week", "month", "6 months", "year") |
n_units |
Integer specifying number of units. |
anchor_table |
Beta |
anchor_vector |
Beta |
base_date |
Beta |
occurence |
Beta |
multiset |
Beta; Logical indicator which controls the exclusion of multiple events within the same event set. |
include_date |
Logical indicator which controls the inclusion of the date variable in the returning data. If creating reports using the -generate_reports- function of approxmapR, then the dates will be included in the alignment_with_date output file if this argument is equal to TRUE - default value is FALSE. |
summary_stats |
Logical controlling printing of summary statistics regarding aggregation. Defaults to TRUE |
output_directory |
The path to where the exports should be placed. |
Aggregated dataframe that has sequence id, itemset (period) and event (item)
library(approxmapR) data("mvad") # This will aggregate the data using a 6-month frame, i.e. all events which occurred # in 6-months will be grouped into an event set mvad %>% aggregate_sequences(format = "%Y-%m-%d", unit = "month", n_units = 6)
