The following is my report for week 2. As a part of this homework, data importing exercises were executed.
Data Sets:
library('readr') # For reading csv files in 1,2, 5
library('readxl') # For reading excel files from drive in 3
library('gdata') # For reading excel file from website in 4
library('DT') # To print tables1. Download & import the csv file located at: https://bradleyboehmke.github.io/public/data/reddit.csv
reddit <- read_csv('../data/reddit.csv')
head(reddit[, 1:5])str(reddit, give.attr = F)## Classes 'tbl_df', 'tbl' and 'data.frame': 32754 obs. of 14 variables:
