plot.segmag

object of class <code><a rd-options="" href="/link/segmag?package=segmag&version=1.2.4" data-mini-rdoc="segmag::segmag">segmag</a></code>

numeric vector of critical cutoffs that are drawn as horizontal
red lines. Use <code><a rd-options="" href="/link/bootstrap_critical_cutoffs?package=segmag&version=1.2.4" data-mini-rdoc="segmag::bootstrap_critical_cutoffs">bootstrap_critical_cutoffs</a></code> in order to
determine the cutoffs for a specific segmag object.

cutoffs

numeric vector of event boundary times to highlight in the plot

eb_times

object of class <code><a rd-options="" href="/link/segmag?package=segmag&version=1.2.4" data-mini-rdoc="segmag::segmag">segmag</a></code>. If this value is set
than the difference in segmentation magnitude of
segmag - segmag_substract is drawn.

segmag_substract

string, optional name of file where to save plot (.png is added automatically)

save_as_png

paramters passed to generic plot function


Draws a plot depicting the segmentation magnitude resulting from overlaid
Gaussians for each key press time across participants. If segmag_substract
is defined then the difference in segmentation magnitude of segmag - segmag_substract
is drawn.


Contains functions that help to determine event
boundaries in event segmentation experiments by bootstrapping a critical
segmentation magnitude under the null hypothesis that all key presses were
randomly distributed across the experiment. Segmentation magnitude is
defined as the sum of Gaussians centered at the times of the segmentation
key presses performed by the participants. Within a participant, the maximum
of the overlaid Gaussians is used to prevent an excessive influence of a
single participant on the overall outcome (e.g. if a participant is pressing
the key multiple times in succession). Further functions are included, such
as plotting the results.
