as_npc {ggpubr} | R Documentation |
Convert Character Coordinates into Normalized Parent Coordinates (NPC)
Description
Convert character coordinates to npc units and shift postions to avoid overlaps when grouping is active. If numeric validate npc values.
Usage
as_npc(
value,
group = 1L,
step = 0.1,
margin.npc = 0.05,
axis = c("xy", "x", "y")
)
as_npcx(value, group = 1L, step = 0.1, margin.npc = 0.05)
as_npcy(value, group = 1L, step = 0.1, margin.npc = 0.05)
Arguments
value |
numeric (in [0-1]) or character vector of coordinates. If
character, should be one of |
group |
integer ggplot's group id. Used to shift coordinates to avoid overlaps. |
step |
numeric value in [0-1]. The step size for shifting coordinates in npc units. Considered as horizontal step for x-axis and vertical step for y-axis. For y-axis, the step value can be negative to reverse the order of groups. |
margin.npc |
numeric [0-1] The margin added towards the nearest plotting area edge when converting character coordinates into npc. |
axis |
the concerned axis . Should be one of |
Details
the as_npc()
function is an adaptation from
ggpmisc::compute_npc()
.
Value
A numeric vector with values in the range [0-1] representing npc coordinates.
