stamp.stgroup.summary {stampr} | R Documentation |
Compile stamp summary statistics by space-time group
Description
The function stamp.stgroup.summary
compiles summary statistics for each STAMP space-time grouping.
Specifically, it computes the area of each STAMP event type (e.g., generation, expansion, etc.)
within each grouping. It also computes the number of events belonging to each event type.
Usage
stamp.stgroup.summary(stmp, area = TRUE, count = TRUE)
Arguments
stmp |
a |
area |
logical, whether or not to compute the STAMP event areas. |
count |
logical, whether or not to compute the count of STAMP events within each group. |
Details
stamp.stgroup.summary
computes area and count summary statistics of STAMP output derived from multi-time analysis using stamp.multichange.
stamp.multichange is just a wrapper function for applying stamp to multiple time periods in the same dataset. Note that if
both area
and count
are set to FALSE
, stamp.stgroup.summary
returns a
data.frame
with just the stgroup IDs as the only column.
Value
A data.frame
where rows are stamp groups and columns correspond to the STAMP event types (ID, areas, and counts).
