Description Usage Arguments Value Author(s) See Also Examples

Aggregate values in x for bins defined on y: all values in x for values in y falling into a bin (defined on y) are aggregated with the provided function FUN.

bin(
  x,
  y,
  size = 1,
  breaks = seq(floor(min(y)), ceiling(max(y)), by = size),
  FUN = max
)

`x`	`numeric` with the values that should be aggregated/binned.
`y`	`numeric` with same length than `x` with values to be used for the binning.
`size`	`numeric(1)` with the size of a bin.
`breaks`	`numeric` defining the breaks (bins).
`FUN`	`function` to be used to aggregate values of `x` falling into the bins defined by `breaks`.

list with elements x (aggregated values of x) and mids (the bin mid points).

## Define example intensities and m/z values
ints <- abs(rnorm(20, mean = 40))
mz <- seq(1:length(ints)) + rnorm(length(ints), sd = 0.001)

## Bin intensities by m/z bins with a bin size of 2
bin(ints, mz, size = 2)

## Repeat but summing up intensities instead of taking the max
bin(ints, mz, size = 2, FUN = sum)
