bug in fimd.R code

[moviedo5]

Error in hist.default(mis, plot = FALSE, breaks = b) :
some 'x' not counted; maybe 'breaks' do not span range of 'x
mi.hist(Yimp, Yobs,
b = seq(-20, 200, 10), type = "continuous",
gray = FALSE, lwd = lwd,
obs.lwd = 1.5, mis.lwd = 1.5, imp.lwd = 1.5,
obs.col = mdc(4),mis.col = mdc(5), imp.col = "transparent",
mlt = 0.08, main = "", xlab = "Ozone (ppb)")
Solution: let the minimum of b be -40 for example?

I would suggest to directly remove b here since the default setting in mi.hist is pretty good.
