R help - Oct 2009 - lasso plot using LARS

When plotting a lars object, I cannot find a way to plot solid lines.
Even when the arguments breaks=F and lty="solid" are used, the
vertical
lines at the break points do not plot but asterisks indicating the
breaks still plot as part of each path leaving solid lines broken up by
asterisks at the break points.  I'm using the following code.

 

larsfit <- lars(X,y,type="lasso")

larsfit

plot(larsfit,breaks=F,lty="solid")

 

Any suggestions in removing the asterisks and plotting truly solid
lines?

 

Thanks

Within the plot.lars code, change the type argument to matplot from 'b'
to 'l':

library(lars)
myplot.lars <- edit(plot.lars)
#change type = 'b' to type = 'l' in the call to matplot
data(diabetes)
object <- with(diabetes,  lars(x,y))
myplot.lars(object, lty = 1, breaks = FALSE)
