sol.idetect_seq {breakfast}  R Documentation 
This function uses the IsolateDetect method in its original sequential way in order to create the solution path. It is developed to be used with the thresholding model selection rule.
sol.idetect_seq(x, points = 3)
x 
A numeric vector containing the data to be processed 
points 
A positive integer with default value equal to 3. It defines the distance between two consecutive end or startpoints of the right or leftexpanding intervals, as described in the IsolateDetect methodology. 
The IsolateDetect method and its algorithm is described in "Detecting multiple generalized changepoints by isolating single ones", A. Anastasiou & P. Fryzlewicz (2021), Metrika, https://doi.org/10.1007/s00184021008216.
