timeFirstPeak_points: Find time to true strain peaks using percentagepoints...

In dloewenstein/straindys: A collection of tools to calculate different strain and dyssynchrony metrcis for CMR FT

Description

Find time to true strain peaks using percentagepoints criteria for circumferential/longitudinal strain

Usage

timeFirstPeak_points(x, strain, thresh, incr, position.firstStrainColumn)

Arguments

x	dataframe containing the strain columns in a long format.
strain	the strain variable you want to mutate, written inside "".
thresh	number of negative percentagepoints that a valley has to reach to be considered a true valley.
incr	number of percentagepoints by which the strain increase between valley and the following peak has to reach.
position.firstStrainColumn	the index position for the first strain segment in the dataframe

Value

A dataframe with id and a straincolumn containing the time for the first peak fulfilling the criteria
