...e MICE command where the imputation methods is
logistic regression (option logreg). However I have been unsuccessful when
I've tried to impute the binary variable using linear discriminant analysis
(option lda) Instead I get the following error message "Error in
colMeans(as.matrix(imp[[visitSequence[j]]])) : 'x' must be numeric"
I can however impute using the elementary imputation method "impute.lda".

Saludo gente, antes que nada gracias por la ayuda que puedan aportarme, soy
iniciante en R, estoy usando el paquete Mice para realizar imputaciones
múltiples sobre variables en su mayoría categóricas. El problema está que
cuando expresó este comando imp <- mice(dataset,method="polr",maxit=1)
donde el dataset es un data.frame me tirá este error :
iter imp variable
1 1 pial1a
