- Hex Conversion Command No Longer Working
I am using H2O atop R and have been importing data sets from our database. I then convert the data set to HEX so I can model with H2O. This had been working fine until today, when I started getting this error:

Error in as.h2o(NL2LSet) : client must be a H2OClient object

Not sure what has changed, as this used to work:

L2L.hex <- as.h2o(NL2LSet)

Thanks!

Strangely,it gives an error and says

The name Long does not exist in this context

I haveto use this because I get error of format exception when I use this:

`int intAgain = int.Parse(value, System.Globalization.NumberStyles.HexNumber);`

I also get index out of range error too.So what will be the solution to convert hex to int in my case ?Any help will be appreciated.
