plot_Histogram() - argument breaks is not treated correctly

[RLumSK]

Summary

The additional argument breaks, passed via ... to the function graphics::hist is erroneously treated and if used leading to a wrong plot output. In particular, the argument breaks fails if a single numeric value is provided. However, according to the manual (?hist) the argument breaks allows for

one of:
a vector giving the breakpoints between histogram cells,
a function to compute the vector of breakpoints,
a single number giving the number of cells for the histogram,
a character string naming an algorithm to compute the number of cells (see ‘Details’),
a function to compute the number of cells.

Example

## load data
data(ExampleData.DeValues, envir = environment())
ExampleData.DeValues <-
  Second2Gray(ExampleData.DeValues$BT998, dose.rate = c(0.0438,0.0019))

## plot histogram the easiest way
plot_Histogram(ExampleData.DeValues, breaks = 5)

Traceback

Please check, amongst others, line 236:

    xlim.plot <- range(breaks.plot)

Possible solution

The automatic xlim values should not set using the manually set breaks, but the real one created by
hist.
