Cleanup plot.bfast

[GreatEmerald]

Currently the return value of plot.bfast is random and differs depending on the last command run, usually returning a numeric 1 from par() which is meaningless. It should not return anything.

hey, excuse me, I met a problem during my work, when I enter plot(... , ANOVA=TRUE) in R, it would return the slope and prob, but now it just return NULL now, how could I calculate the slope under this condition?
