find_peaks: Detect local maxima in time series

In GCalignR: Simple Peak Alignment for Gas-Chromatography Data

Detect local maxima in time series

Description

Detects peaks in a vector and calculates the peak height. This function is only appropriate for symmetric gaussian peaks and does not take into account any baseline correction as it required in 'real word' data. Therefore, it does not substitute sophisticated peak detection and integration tools and is only used for illustration purposes in our vignettes.

Usage

find_peaks(df)

Arguments

df	A data frame containing x and y coordinates.

Value

A data frame containing x and y coordinates of peaks.

Examples

## create df
df <- data.frame(x = 1:1000, y = dnorm(1:1000,300,20))
## plot
with(df, plot(x,y))
## detect peak
find_peaks(df)
