This function plots FEve index for a given pair of functional axes and one or several assemblages. It adds Minimum Spanning Tree (MST) of a given assemblage on the background plot.

)Arguments
- ggplot_bg
a ggplot object of the plot background retrieved through the
background.plotfunction.- asb_sp_coord2D
a list of matrix (ncol = 2) with coordinates of species present in each assemblage for a given pair of functional axes.
- asb_sp_relatw
a list of vector gathering species relative weight in each assemblage. It can be retrieved through the
alpha.fd.multidim.- asb_mst
a list (with names as in
asb_sp_coord2D) of vectors with names of species linked in the MST of the studied assemblage.- plot_sp
a logical value indicating whether species of each assemblage should be plotted or not. Default:
plot_sp = TRUE- shape_sp
a numeric value referring to the shape of the symbol used for species plotting if one assemblage to plot or a vector numeric values if several assemblages to plot. If more than one assemblage to plot, the vector should be formatted as: c(asb1 = "firstRshape", asb2 = "secondRshape", ...).
- color_sp
a R color name or an hexadecimal code referring to the color of species if one assemblage to plot or a vector of R color names or hexadecimal codes if several assemblages to plot. If more than one assemblage to plot, the vector should be formatted as: c(asb1 = "firstRcolorname", asb2 = "secondRcolorname", ...).
- fill_sp
a R color name or an hexadecimal code referring to the color of species symbol filling (if
shape_sp> 20) if one assemblage to plot or a vector of R color names or hexadecimal codes if several assemblages to plot. If more than one assemblage to plot, the vector should be formatted as: c(asb1 = "firstRcolorname", asb2 = "secondRcolorname", ...).- color_mst
a R color name or an hexadecimal code referring to the color the MST if one assemblage to plot or a vector of R color names or hexadecimal codes if several assemblages to plot. If more than one assemblage to plot, the vector should be formatted as: c(asb1 = "firstRcolorname", asb2 = "secondRcolorname", ...).
- width_mst
a numeric value referring to the width of segments of the MST if one assemblage to plot or a vector numeric values if several assemblages to plot. If more than one assemblage to plot, the vector should be formatted as: c(asb1 = "firstRsize", asb2 = "secondRsize", ...).
- linetype_mst
a numeric value referring to the linetype of the segments representing the MST if one assemblage to plot or a vector numeric values if several assemblages to plot. If more than one assemblage to plot, the vector should be formatted as: c(asb1 = "firstRlinetype", asb2 = "secondRlinetype", ...).
Value
A ggplot object showing FEve index on the background plot.
