peaks {MethodOpt} | R Documentation |
Peak searching algorithm without retention times
Description
Returns the maxima, the times they occur at, the index location of the maxima, and the next viable peaks with times after the first 'keep'.
Usage
peaks(
data,
begin_search = NULL,
end_search = NULL,
keep = 11,
precision = 15,
factor = 10,
bl_noise = 0
)
Arguments
data |
time versus intensity dataframe. |
begin_search |
time at which to start the search for the peaks. |
end_search |
time at which to stop the search for the peaks. |
keep |
a whole number indicating how many peaks to search for and return. |
precision |
an integer indicating the size of the window for searching for local maxima. |
factor |
constant of proportionality indicating the cutoff peak height (i.e., peaks greater than 'factor' times height are not returned as viable peaks). |
bl_noise |
constant level at which response should be considered as noise. |
Value
list containing spectra maxima,the times they occur at, the index location of the maxima, and the the same info for the next viable peaks with times after the first 'keep'.
