Defines breaks for binSize sized bins for values ranging from fromX to toX.

1	breaks_on_binSize(fromX, toX, binSize)

`fromX`	numeric(1) specifying the lowest value for the bins.
`toX`	numeric(1) specifying the largest value for the bins.
`binSize`	numeric(1) defining the size of a bin.

This function creates breaks for bins of size binSize. The function ensures that the full data range is included in the bins, i.e. the last value (upper boundary of the last bin) is always equal toX. This however means that the size of the last bin will not always be equal to the desired bin size. See examples for more details and a comparisom to R's seq function.

A numeric vector defining the lower and upper bounds of the bins.

binYonX for a binning function.

Other functions to define bins: breaks_on_nBins

## Define breaks with a size of 0.13 for a data range from 1 to 10:
breaks_on_binSize(1, 10, 0.13)
## The size of the last bin is however larger than 0.13:
diff(breaks_on_binSize(1, 10, 0.13))
## If we would use seq, the max value would not be included:
seq(1, 10, by = 0.13)

## In the next example we use binSize that leads to an additional last bin with
## a smaller binSize:
breaks_on_binSize(1, 10, 0.51)
## Again, the max value is included, but the size of the last bin is < 0.51.
diff(breaks_on_binSize(1, 10, 0.51))
## Using just seq would result in the following bin definition:
seq(1, 10, by = 0.51)
## Thus it defines one bin (break) less.
