[R] lasso plot using LARS

[Kingsford Jones]

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)
