abs_to_ratio: Convert absolute quantitation to relative ratios.
In mstherm: Analyze MS/MS Protein Melting Data

Description Usage Arguments Details Value

abs_to_ratio takes a vector of absolute values and returns a vector of ratios relative to some starting point.

1	abs_to_ratio(x, method = "first")

`x`	vector of numeric absolute quantitation values
`method`	method to use to determine starting value (denominator)

The denominator used to calculate relative protein concentrations can affect the ability to model noisy data. In the theoretically ideal scenario, everything would be relative to the lowest temperature point. However, other methods can be used to help alleviate problems related to noise. Available methods include:

"first": Use the first value (lowest temperature point) (default)
"max": Use the maximum value
"top3": Use the mean of the three highest values
"near": Use the median of all values greater than 80 the first value

A numeric vector of the same length as input
