The legend()-Function shows a different behaviour than it did in Version 1.6.1.
It plots a black box left of the legend lines on each legend row. In 1.6.1 there
was just the line in appropriate color for each row in the legend (i was using
exactly the same legend statement and same plot function).
My legend statement is:
legend(x=(daysold+2), y=0.95*maxy.j, legend=leg.txt, col = leg.col, lty=1,angle
= NULL, density = NULL, bty = "o", xjust = 0, yjust = 1, x.intersp = 1,
y.intersp = 1, ncol = 1, horiz = FALSE)

If i write the statement as follows:
legend(x=(daysold+2), y=0.95*maxy.j, legend=leg.txt, col = leg.col, lty=1,angle
= NULL, density = NULL, bty = "o", xjust = 0, yjust = 1, x.intersp = 1,
y.intersp = 1, ncol = 1, horiz = FALSE, merge = TRUE)

The merge = TRUE statemen merges the black boxes (one for each row) and the
colored lines in the legend, but the boxes remain there.
