stamp_text_ljust.Rd
This function adds a text annotation layer
stamp_text_ljust( x = 0 + nudge_x, y = 0 + nudge_y, label = "some\ntext", text_wrap = FALSE, char_width = 40, alpha = 1, angle = 0, color = "black", family = "Times", fontface = "bold", hjust = 0, lineheight = 0.85, size = 8, vjust = 0.5, xy = NULL, parse = FALSE, nudge_x = 0, nudge_y = 0 )
label | defaults with a message about use |
---|---|
alpha | numeric between 0 and 1 indicating transparency, defaults to 1 fully opaque, zero is fully transparent |
color | a character string indicating color, defaults to "black", for other named colors check out https://evamaerey.github.io/ggplot2_grammar_guide/named_colors |
family | font family |
hjust | horizontal justification, between 0 and 1, defaults to .5 |
lineheight | spacing between lines if text is wrapped |
size | size of text |
vjust | vertical justification, between 0 and 1, defaults to .5 |
xy | a data frame where the first two columns contain x and y positional values |
parse | If TRUE, the labels will be parsed into expressions and displayed as described in ?plotmath. |
nudge_x | Horizontal adjustment to nudge labels by. Useful for offsetting text from points, particularly on discrete scales. |
nudge_y | Vertical adjustment to nudge labels by. Useful for offsetting text from points, particularly on discrete scales. |
