Statistical modeling with DataTable

Description

A number of wrappers are implemented for performing statistical procedures, such as model fitting, with DataTable objects.

Tabulation

xtabs(formula = ~., data, subset, na.action, exclude = c(NA, NaN), drop.unused.levels = FALSE): Like the original xtabs, except data is a DataTable.

See Also

DataTable for general manipulation, DataFrame for an implementation that mimics data.frame.

Examples

  df <- DataFrame(as.data.frame(UCBAdmissions))
  xtabs(Freq ~ Gender + Admit, df)
