  string,
  max_cex = 1,
  min_cex = 0.5,

Arguments

string	A character vector with the text to be plotted
max_cex	A real number, giving the maximum *cex* (**c**haracter **ex**pansion) for the string to be plotted
min_cex	minimum character expansion to be used on the title
string_font	font type to be used on the title
max_height	A real number, giving the maximum height to be covered by the text
init_strwrap_width	A real number indicating the minimum number of characters to be plotted by line
min_width	A real number, giving the minimum width to be occupied by the string
max_width	A real number, giving the maximum width to be occupied by the string
whole	Boolean, indicating if the whole string should be plotted even if it surpasses the limits established in previous arguments
