Hi,
I tried processing data in order to get an xgb.DMatrix object, but I ran into difficulties. All examples found in the xgboost package documentation or Xgboost presentation vignette are basically useless as examples for what I want to do. My undestanding goes as far as knowing there should be a vector of target variables, and a matrix of explanatory variables with column heads removed.
Can you share your actual experiences using this package? Can I safely use a regular data file to perform an analysis? Do you have examples of using actual data to get it in the xgb.DMatrix format?
Many thanks

Dear Adrian Otoiu,
You can use both regular data-frames and xgb.DMatrix objects.
The following script is an example about using xgboost with a regular data-frame:
