I got an error when exporting data from R

问题

When I wanted to export my results from R with this code,

write.table(imp, "c:/immp.txt", sep="\t")

I got this error:

Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) : 
  cannot coerce class ""mids"" to a data.frame

Sorry for a simple question,I am new to R. Thanks for your help

回答1:

It looks like you're trying to export a "mids" object, as opposed to a data frame. You'll need to convert it to a data frame before using write.table, which you should be able to do with complete():

impframe <- complete( imp, action = "long", include = TRUE )

Adjust the options as necessary for your data. Then try your write.table command.
