To Do

  • Consider using the haven package for importing SAS, Stata, and SPSS files; haven stores labels as the label attribute of each variable as does Hmisc; it converts date and time variables automatically and allows one to specify a format catalog along with the primary dataset
  • See if the readstata13 package has advantages over the foreign package for Stata file import
  • Consider creating xl.get using the readxl package to read .xls and .xlsx Excel files
  • In impute.transcan, sense if a variable in data is not a factor whereas it was treated as a factor during aregImpute; it should be converted to factor before the line v[sub] <- ... levels(as.integer...)) is run
