Get the analog data of a c3d object in a data frame.
Arguments
- x
A c3d object, as imported by
c3d_read().
Value
A data.frame with with n rows and m columns, where n is the number of frames recorded times the number of analog subframes per frame, and m as the number of recorded analog channels.
Details
The analog data of imported c3d objects in c3dr is saved as a list of
lists. This is good for internal handling, but for analysis a table format (a
data frame) is often more convenient.c3d_analog() returns the analog data
from an imported c3d object as a data frame.
Examples
# Import example data
d <- c3d_read(c3d_example())
# get analog data
a <- c3d_analog(d)
