Arguments

• x: object of class sf
• var: name(s) of the variable(s) to plot
• pal: a set of colors or a palette name (from hcl.colors )
• alpha: if pal is a hcl.colors palette name, the alpha-transparency level in the range [0,1]
• rev: if pal is a hcl.colors palette name, whether the ordering of the colors should be reversed (TRUE) or not (FALSE)
• val_order: values order, a character vector that matches var modalities
• border: border color
• pch: pch type of pch if x is a POINT layer
• cex: cex cex of the symbols if x is a POINT layer
• lwd: border width
• cex_na: cex for NA values if x is a POINT layer
• pch_na: pch for NA values if x is a POINT layer
• col_na: color for missing values
• leg_pos: position of the legend, one of 'topleft', 'top','topright', 'right', 'bottomright', 'bottom', 'bottomleft', 'left' or a vector of two coordinates in map units (c(x, y)). If leg_pos = NA then the legend is not plotted. If leg_pos = 'interactive' click onthe map to choose the legend position.
• leg_title: legend title
• leg_title_cex: size of the legend title
• leg_val_cex: size of the values in the legend
• leg_no_data: label for missing values
• leg_frame: whether to add a frame to the legend (TRUE) or not (FALSE)
• leg_frame_border: border color of the legend frame
• leg_adj: adjust the postion of the legend in x and y directions
• leg_size: size of the legend; 2 means two times bigger
• leg_box_border: border color of legend boxes
• leg_box_cex: width and height size expansion of boxes
• leg_fg: color of the legend foreground
• leg_bg: color of the legend backgournd
• add: whether to add the layer to an existing plot (TRUE) or not (FALSE)

Returns

No return value, a map is displayed.
