fun_trim() corrected: breaks of hist() set to default value because otherwise create a bug with c(10,0,0,0,0,0)

fun_gg_scatter() empty legend space improved but still errors to fix, fun_gg_boxplot() -> incorporation of legend space still in progress

fun_gg_get_legend() created, fun_gg_scatter() now with empty legend space but still errors to fix, fun_gg_boxplot() -> incorporation of legend space still in progress

fun_gg_boxplot() stat display seem fixed, remain y.tick.nb to solve, because of ggplot::ylim() that redraw breaks

fun_gg_boxplot() color with tidy and dot.categ.class.order seem fixed, remain y.tick.nb to solve, because of ggplot::ylim() that redraw breaks

problem of y-axis inversion with fun_gg_boxplot when y.lim argument is decreasing: problem code in blue, see also https://github.com/tidyverse/ggplot2/issues/3948

fun_gg_boxplot() intertick improved. Everything seems fine for this one. fun_inter_ticks() now deals with log = no. fun_scatter() bug fixed but still have to work on interticks

fun_gg_boxplot() scale log2 and log10 fixed. Everything seems fine for this one. fun_inter_ticks() function created. fun_scatter() -> problem of return:  not good for color attribution, and name.coord not good neither

fun_test() now with expect.error argument, fun_gg_boxplot() updated for ggplot2 3.3.0 + accepts lemon::facet_rep... functions
