aes mapping

horizontal adjustment

align tip lab or not, logical

linetype for adding line if align = TRUE

line size of line if align = TRUE

one of 'text', 'label', 'shadowtext', 'image' and 'phylopic'

tiplab offset, horizontal adjustment to nudge tip labels, default is 0.

display tip labels as y-axis label, only works for rectangular and dendrogram layouts

additional parameter

additional parameters can refer the following parameters.

The following parameters for geom="text".

• size control the size of tip labels, default is 3.88.

• colour control the colour of tip labels, default is "black".

• angle control the angle of tip labels, default is 0.

• vjust A numeric vector specifying vertical justification, default is 0.5.

• alpha the transparency of text, default is NA.

• family the family of text, default is 'sans'.

• fontface the font face of text, default is 1 (plain), others are 2 (bold), 3 (italic), 4 (bold.italic).

• lineheight The height of a line as a multiple of the size of text, default is 1.2 .

• nudge_x horizontal adjustment to nudge labels, default is 0.

• nudge_y vertical adjustment to nudge labels, default is 0.

• check.overlap if TRUE, text that overlaps previous text in the same layer will not be plotted.

• parse if TRUE, the labels will be parsed into expressions, if it is 'emoji', the labels will be parsed into emojifont.

The following parameters for geom="label".

• size the size of tip labels, default is 3.88.

• colour the colour of tip labels, default is "black".

• fill the colour of rectangular box of labels, default is "white".

• vjust numeric vector specifying vertical justification, default is 0.5.

• alpha the transparency of labels, default is NA.

• family the family of text, default is 'sans'.

• fontface the font face of text, default is 1 (plain), others are 2 (bold), 3 (italic), 4 (bold.italic).

• lineheight The height of a line as a multiple of the size of text, default is 1.2.

• nudge_x horizontal adjustment to nudge labels, default is 0.

• nudge_y vertical adjustment, default is 0.

• check.overlap if TRUE, text that overlaps previous text in the same layer will not be plotted.

• parse if TRUE, the labels will be parsed into expressions, if it is 'emoji', the labels will be parsed into emojifont.

• label.padding Amount of padding around label, default is 'unit(0.25, "lines")'.

• label.r Radius of rounded corners, default is 'unit(0.15, "lines")'.

• label.size Size of label border, in mm, default is 0.25.

The following parameters for geom="shadowtext", some parameters are like to geom="text".

• bg.colour the background colour of text, default is "black".

• bg.r the width of background of text, default is 0.1 .

The following parameters for geom="image" or geom="phylopic".

• image the image file path for geom='image', but when geom='phylopic', it should be the uid of phylopic databases.

• size the image size, default is 0.05.

• colour the color of image, default is NULL.

• alpha the transparency of image, default is 0.8.

The following parameters for the line when align = TRUE.

• colour the colour of line, default is 'black'.

• alpha the transparency of line, default is NA.

• arrow specification for arrow heads, as created by arrow(), default is NULL.

• arrow.fill fill color to usse for the arrow head (if closed), default is 'NULL', meaning use 'colour' aesthetic.
