z[.td.data.frame: Extract Teradata Data Frame

In nonsleepr/teradataR: Teradata R Package

Description

Allow manipulation and extraction of a td data frame.

Usage

## S3 method for class 'td.data.frame'
x[i, j]

Arguments

x	td data frame.
i	element to extract
j	element to extract

Details

This overloaded function operates almost exactly like a data frame extract. It can be used to reduce the number of columns by using the index values. One noticeable difference is that a td data frame has no actual data in the client. This means that row operations don't extract certain rows like a data frame object. You must use td.sample if you wish to alter table sizes.

Value

td data frame of new column dimensions.

Examples

## Not run: 
tdf[3]  #returns td data frame with just column 3
tdf["age"]  #returns td data frame with column age

## End(Not run)
