h2o (un) ordered factor

Question

Hi I have a problem with the h2o(3) not loading my factors.

The Problem is similar to: Unable to convert data frame to h2o object

However I tried to use: myData<- data.frame(apply(myData, 2, factor, ordered=FALSE)) but the error persists: Provided column type c("ordered", "enum") is unknown.

Is there some other method to ensure that my factor is unordered?

here a subset of the data

dput(droplevels(head(myData[1:5])))
structure(list(Id = structure(1:6, .Label = c("    2", "    5", 
"    6", "    7", "    8", "   10"), class = "factor"), factor1 = structure(c(1L, 
1L, 1L, 1L, 1L, 1L), .Label = "1", class = "factor"), factor2 = structure(c(3L, 
1L, 5L, 4L, 2L, 2L), .Label = c("A1", "D2", "D3", "D4", "E1"), class = "factor"), 
    factor3 = structure(c(1L, 2L, 2L, 1L, 2L, 2L), .Label = c("10", 
    "26"), class = "factor"), factor5 = structure(c(1L, 
    1L, 1L, 1L, 1L, 2L), .Label = c("2", "3"), class = "factor")), .Names = c("Id", 
"factor1", "factor2", "factor3", "factor5"
), row.names = c(NA, 6L), class = "data.frame")
> head(myData[1:5])

Please make your question self-contained. Include a [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) with sample input and your code (including all relevant libraries). — MrFlick, Nov 27 '15 at 19:56
@geoHeil you did include `print` of `head` of your data, not your data. — jangorecki, Nov 27 '15 at 20:04
Those factors *are* unordered. Compare ` str(factor(1:10))` to `str(ordered(1:10))`. Plus that's not a very friendly way to share data. A `dput()` would have been better as described in the link i provided. — MrFlick, Nov 27 '15 at 20:04
That doesn't change the fact that those are called unordered factors in R. What exactly is your desired output? — MrFlick, Nov 27 '15 at 20:15
I try to load the dataset into h2o. However I get the error from above. I try to find a workaround to make it work. Or would like to get some information from h2o which column is the one causing the error. — Georg Heiler, Nov 27 '15 at 20:17

This:

sapply(myData, class)

prints the classes of each column and helps to identify the one which is causing the errors.

I will exclude / convert that column manually.
