Preview and print the results of running a query

This is used to implement print() for the sedonadb_dataframe or can be used to explicitly preview if options(sedonadb.interactive = FALSE).

sd_preview(.data, n = NULL, ascii = NULL, width = NULL)

Arguments

.data

A sedonadb_dataframe or an object that can be coerced to one.

n

The number of rows to preview. Use Inf to preview all rows. Defaults to getOption("pillar.print_max").

ascii

Use TRUE to force ASCII table formatting or FALSE to force unicode formatting. By default, use a heuristic to determine if the output is unicode-friendly or the value of getOption("cli.unicode").

width

The character width of the output. Defaults to getOption("width").

Value

.data, invisibly
