This function finds all peaks (local maxima) in a spectrum, using a user
selectable size threshold relative to the tallest peak (global maximum). This
a wrapper built on top of function peaks from package splus2R.
numeric value between 0.0 and 1.0 indicating the size
threshold below which peaks will be ignored.
span
a peak is defined as an element in a sequence which is greater
than all other elements within a window of width span centered at that
element. The default value is 3, meaning that a peak is bigger than both of
its neighbors. Default: 3.
strict
logical flag: if TRUE, an element must be strictly greater than
all other values in its window to be considered a peak. Default: TRUE.
na.rm
logical indicating whether NA values should be stripped
before searching for peaks.
Value
an object like s.irrad of logical values. Values that are TRUE
correspond to local peaks in the data.
