LLN_plot(.plot = NULL, .true_value = NULL, .indicator_values,

  .show_text = TRUE, ...)

`.plot`	The plot upon which additional information should be added. A new plot will be created if the default value `NULL` is used.
`.true_value`	The true value of the event of interest. The default value `NULL` can be used to create a plot also in the case this value is unknown.
`.indicator_values`	A vector with the result of an indicator-function that tells us whether the desired event was observed in the different cases of interest. This could e.g. be related to the result of a coin-toss being head.
`.m_of_n`	An integer that shows how many of the indicator-values that should be used. This is included in order to enable an animation of the development. The default value `NULL` will set this argument to be the length of the vector given in `.indicator_values`.
`.colours`	A character-vector, default value `c("red", "black")`, that gives the `colour`-arguments to be used for the lines showing `.indicator_values` and `.true_value`. The second part will be ignored when `.true_value=NULL`.
`.ltys`	An integer-valued vector, default value `c(1,2)`, that gives the `lty`-arguments to be used for the lines showing `.indicator_values` and `.true_value`. The second part will be ignored when `.true_value=NULL`.
`.show_text`	Logical value, default `TRUE` that will add the true value given in `.true_value` (when known) and the estimated value based on `.m_of_n` and `indicator_values`.
`...`	Additional arguments to be used in the `xy_sprintf`-function.
