Error without an error being thrown

Question

I\'m trying to multiply impute some data, and it\'s failing in a very odd way. I have options(error=recover) set, and mi() doesn\'t throw an error, but it does stop imputin

Answer 1

Since the error=recover option is not working, an alternative that does work is to set options(error=dump.frames). That will get you some information about the error, which you can either print out or, more usefully, examine with debugger()

ls()
# [1] "dat"
options(error=dump.frames)
mi(dat)
ls()
# [1] "dat"       "last.dump"  # Apparently there WAS an error

# INVESTIGATE WITH debugger()
debugger(dump=last.dump)

# ALTERNATIVELY, PRINT last.dump TO CONSOLE
last.dump

$`mi(dat)`
<environment: 0x05155c44>

$`mi(dat)`
<environment: 0x05158f30>

$`.local(object, ...)`
<environment: 0x05158cac>

$`mi.default(object, info, n.imp, n.iter, R.hat, max.minutes, rand.imp.method`
<environment: 0x047dc3a0>

attr(,"error.message")
[1] "Error in aveVar[s, i, ] <- c(avevar.mean, avevar.sd) :
\n  number of items to replace is not a multiple of replacement length\n"
attr(,"class")
[1] "dump.frames"
