findPeak {tomoda} | R Documentation |
Find the position of peak in a vector.
findPeak(x, threshold = 1, length = 4)
x |
A numeric vector. |
threshold |
Integer, only values bigger than |
length |
Integer, minimum |
A numeric vector. The first element is the start index and the second element is the end index of the peak.
If multiple peaks exist, only output the start and end index of the one with maximun length.
If no peak exist, return c(0, 0)
.
# return c(3, 10) findPeak(c(0:5, 5:0), threshold=1, length=4) # Most likely return c(0, 0) findPeak(rnorm(10), threshold=3, length=3)
