hexVP.abline {hexbin} | R Documentation |
This function adds one or more straight lines through the current plot.
hexVP.abline(hvp, a, b = NULL, h = numeric(0), v = numeric(0), col = "black", lty = 1, lwd = 2, ...)
hvp |
A hexViewport object that is currently on the active device |
a,b |
the intercept and slope or if b is NULL an lm
object or a vector of length 2 with c(intercept,slope) |
h |
the y-value for a horizontal line. |
v |
the x-value for a vertical line. |
col |
line color |
lty |
line type |
lwd |
line width |
... |
graphical parameters |
The first form specifies the line in intercept/slope form (alternatively 'a' can be specified on its own and is taken to contain the slope and intercept in vector form).
The h=
and v=
forms draw horizontal and vertical
lines at the specified coordinates.
The coef
form specifies the line by a vector containing the
slope and intercept.
lm
is a regression object which contains reg$coef
. If it is
of length 1 then the value is taken to be the slope of a line
through the origin, otherwise, the first 2 values are taken to be
the intercept and slope
