x: Describes the x coordinates of a experiment design
y: Describes the y coordinates of a experiment design
factor_name_1: Which factor should be used for plotting, needs to be a column in outdesign$book
factor_name_2: Which factor should be used for plotting, needs to be a column in outdesign$book
labels: Describes the column from that the plots are taken to display them
width: numeric value, describes the width of a plot in an experiment
height: numeric value, describes the height of a plot in an experiment
space_width: numeric value, describes the share of the space of the plots. 0=only space, 1=no space between plots in term of width
space_height: numeric value, describes the share of the space of the plots. 0=only space, 1=no space between plots in term of height
reverse_y: boolean, should the plots of the experiment be changed in reverse order in Row direction? use reverse_y=TRUE to have same sketch as in agricolae. default:reverse_y=FALSE
reverse_x: boolean, should the plots of the experiment be changed in reverse order in column direction? default:reverse_x=FALSE
