generate_nodes: Generate nodes from event logs

In twang2218/pmap: Process Map Visualization

Description

eventlog should be a data.frame, which contains, at least, following columns:

• activity: activity name. (character)

• category: activity category, which is optional. If the category column is missing, the activity column will be used as the category. (character)

• amount: how many time this activity happened in the eventlog

generate_nodes() will generate the node list from the given eventlog for the graph purpose.

Usage

generate_nodes(eventlog, distinct_case = FALSE)

Arguments

eventlog	Event logs
distinct_case	Whether should only count unique case

Value

a nodes data.frame which represents a event log, it contains name, category and amount columns.

Examples

# -----------------------------------------------------
# Generate nodes from eventlog and count every event
# -----------------------------------------------------
eventlog <- generate_eventlog(10000, 100)
nodes <- generate_nodes(eventlog)
print(nodes)
# # A tibble: 10 x 3
#    name              category   amount
#    <chr>             <chr>   <int>
#  1 Activity 1 (normal)  normal    958
#  2 Activity 10 (target) target    948
#  3 Activity 2 (normal)  normal   1011
#  4 Activity 3 (normal)  normal   1030
#  5 Activity 4 (normal)  normal   1072
#  6 Activity 5 (normal)  normal    968
#  7 Activity 6 (normal)  normal   1020
#  8 Activity 7 (normal)  normal    978
#  9 Activity 8 (normal)  normal   1003
# 10 Activity 9 (target)  target   1012
#
# -----------------------------------------------------
# Generate nodes and only count by unique case.
