The function allows the user to define options relating to the print method for data.table.

dt_print_options(class = TRUE, topn = 5, rownames = TRUE,
  nrows = 100, trunc.cols = TRUE)

Arguments

class

should the variable class be printed? (options("datatable.print.class"))

topn

the number of rows to print (both head and tail) if nrows(DT) > nrows. (options("datatable.print.topn"))

rownames

should rownames be printed? (options("datatable.print.rownames"))

nrows

total number of rows to print (options("datatable.print.nrows"))

trunc.cols

if TRUE, only the columns that fit in the console are printed (with a message stating the variables not shown, similar to tibbles; options("datatable.print.trunc.cols")). This only works on data.table versions higher than 1.12.6 (i.e. not currently available but anticipating the eventual release).

Examples

dt_print_options( class = TRUE, topn = 5, rownames = TRUE, nrows = 100, trunc.cols = TRUE)
