Bug in passive imputation

[stefvanbuuren]

The following code should yield a plot with straight lines

library(mice)
meth<- make.method(boys)
pred <- make.predictorMatrix(boys)
meth["bmi"]<- "~ I(wgt / (hgt / 100)^2)"
meth["wgt"]<- "~ I(bmi * (hgt / 100)^2)"
meth["hgt"]<- "~ I(sqrt(wgt / bmi) * 100)"
# pred[c("bmi", "wgt", "hgt"), ] <- 0
imp.path <- mice(boys, 
                 meth=meth,
                 pred=pred,
                 seed=123,
                 maxit = 5)
 plot(imp.path, c("hgt", "wgt", "bmi"))

There is a bug in mice 3.0.0 - mice 3.2.0 that produces wigly lines, and even crashes. I have identified the problem, and will make an update.

Version mice 3.2.1 solves this.
