Print the first few rows and last few rows of a data frame

Description

epi_head_and_tail() prints the first and last few rows of a data.frame

Usage

epi_head_and_tail(df = NULL, rows = 5, cols = 5, last_cols = FALSE)

Arguments

df	data.frame as input
rows	Number of rows to print, default is 5
cols	Number of columns to print, default is 5
