Get the point data of an c3d object in a data frame.
Arguments
- x
A c3d object, as imported by
c3d_read().- format
Either
"wide"(default),"long", or"longest"to determine the format of the resulting data frame. See the Data Formats section for more details.
Value
A data frame of class c3d_data with the c3d point data. The
structure of the data frame depends on the 'format' argument.
Details
The point 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_data() returns the point data from an
imported c3d object as a data frame.
Analyses of data frames may require them to have different formats. For
c3d_data output, different data formats ("wide", "long", "longest")
are available. See the section below for more details. You can convert
between different formats with c3d_convert().
Data Formats
Wide
The wide format has three numeric columns per point (x, y, z). The column
names have the structure pointname_type, so for example the x-coordinate of
a point named C7 has the name C7_x. Each row corresponds to one recording
frame.
Long
The long format has one column per point. The column names correspond to the
names of the points. Each recording frame corresponds to three rows of data
(x, y, z). In additional to the point columns containing numeric data there
are two additional columns: One that indicates the frame number (frame,
numeric) and one that indicates the coordinate type (type, either x, y, or
z, as a character).
Examples
# Import example data
d <- c3d_read(c3d_example())
# wide format (default)
w <- c3d_data(d)
