Description

As axis, but draws a "box" line in the same color as the axis.

Usage

fullaxis(side=1,at=NULL,labels=TRUE,line=NA,pos=NA,outer=FALSE,
 font=NA,lty="solid",lwd=1,lwd.ticks=lwd,col=NULL,col.ticks=NULL,
 hadj=NA,padj=NA,...)

Value

The positions of the tick marks in user units.

Arguments

side: The side of the plot to draw the axis
at: Optional positions in user units for the tick marks.
labels: Optional labels for the tick marks.
line: Optional line into the margin.
pos: Optional position in user units for the axis. Defaults to the edge.
outer: Whether to use the outer margin as for axis.
font: Font for the labels.
lty: Line type.
lwd: Line width for the axis.
lwd.ticks: Line width for the ticks.
col: color for the axis and tick marks. See Details for label color.

Details

fullaxis draws a line to the edges of the plot and then calls axis to draw an axis. fullaxis is mainly useful for drawing a colored axis on a boxed plot. In order to get the tick labels the same color as the axis and ticks, pass the col.axis argument (as part of ...) as well as col. See the example for some useful tips.

Examples

Run this code

 plot(runif(20,-1,1),runif(20,-1,1),xlim=c(-1,1.5),main="Demo of fullaxis",
  xlab="X",ylab="Y",axes=FALSE)
 fullaxis(1,col="red",col.axis="red")
 fullaxis(2,col="blue",col.axis="blue")
 fullaxis(4,at=c(-0.5,0,0.5),labels=c("Negative","Zero","Positive"),pos=1.2,
  col="green",las=1)
 # add a top line to complete the "box"
 xylim<-par("usr")
 segments(xylim[1],xylim[4],xylim[2],xylim[4])
