Calculate the average velocity for a movement path.
1 | summaryAvgVelocity(list, summary.df = NA)
|
list |
A list of data frames, each of which has a column for velocity. |
summary.df |
The data frame object within which you are storing path
summary variables. The default is NA if you do not currently have a summary
data frame object started. When set to |
Calculate the average velocity for a movement path. The units on velocity are equal to the distance units used to record the data per second.
The inputed summary data frame or a new data frame if summary.df is
