gradientLegendGrob {gmaps} | R Documentation |
gradientLegendGrob creates a gradient legend grid graphics object.
gradientLegendGrob<-function( at=seq(0,1,length=5), axis.min=min(at), axis.max=max(at), labels=as.character(at), col.fun=grey, delta=.01, vertical=F, reverse=F, name=NULL, gp=NULL, vp=NULL, ...) grid.gradientLegendGrob(...) widthDetails.gradientLegendGrob(x) heightDetails.gradientLegendGrob(x)
at |
where to place tick marks. |
axis.min |
To specify the axis minimun. |
axis.max |
To specify the axis maximum. |
labels |
specifies specific labels for tick marks. |
col.fun |
function to specify gradient. |
delta |
defines level of precision of gradient, smaller is a finer gradient |
vertical |
controls orientation False implies a horizontal orientation. |
reverse |
controls which side to put the axis on. If true puts the axis on the opposite of the default which depends on the argument for vertical. |
name |
the name of the object. |
gp |
grid graphics parameters, ie. a gpar object. |
vp |
Viewport for the object. used to embed within other objects. |
... |
other parameters passed on, mostly just ignored. |
x |
A GradientLegendGrob object |
