Error in if (abs(x - oldx)< ftol) { : missing value where TRUE/FALSE

The reason for this error is in the row 563. There the choice has
value 1 and Ie has missing value. If the choice has value 0 and Ie
has missing values, then there is no errors.
What should i do to make it work..?
How about excluding all rows having the combination "choice=1" and
"Ie=NA" by using the function 'subset'? Or would this destroy/skew your
data?
