ArrowLines  R Documentation 
Similar to lines
, this function will include
endpoints that are solid points, open points, or arrows (mixandmatch
ready).
ArrowLines( x, y, lty = 1, lwd = 2.5, col = 1, length = 0.1, af = 3, cex.pch = 1.2, ends = c("a", "a"), ... )
x 
A vector of the xcoordinates of the line to be drawn. 
y 
A vector of the ycoordinates of the line to be drawn. This vector
should have the same length as that of 
lty 
The line type. 
lwd 
The line width. 
col 
The line and endpoint color. 
length 
If an end point is an arrow, then this specifies the sizing of
the arrow. See the 
af 
A tuning parameter for creating the arrow. Usually the default
( 
cex.pch 
Plotting character size (if open or closed point at the end). 
ends 
A character vector of length 2, where the first value
corresponds to the start of the line and the second to the end of the line.
A value of
