First things first

  1. Settting the working directory
setwd('C:/User/path/)
  1. Specifing the path for the installed libraries
.libPaths('/Path')
  1. Activating the necessary libraries
library('readr')
library('readxl')
library('tidyverse')
library('magrittr')
library('lubridate')

Languages

The project was created using R

Environement

Rstudio

Phases for the project

  1. Data Collection

Data have been collected from ANZ Virtual Internship

  1. Data Cleaning
1. Dropping unnecessary columns
2. Renaming variables
3. Deciding what to do with NAs values
4. Remaking the date format
5. Spreading data from columns
  1. Exploring the Data

Installing

library('ggplot2)

i am given the chance to visualize my data and discover insights and trends and with

library('writexl')

i will export the new tidy dataset that created for furhter analysis

Installation and paths

Install the necessary for the project libraries with these ways
1.

install.packages('tidyverse')
install.packages('readxl')
install.packages('readr')

OR with devtools

devtools::install_github('path/tidyverse')

Also, check the path for the installed libraries with

.libPaths('path/')

Importing libraries and setting the working directory

  • Installing libraries
install.packages('tidyverse')
install.packages('readxl)
  • Setting the working directory
+ setwd('')
  • Installing libraries from github with remotes package
    remotes::install_github("rstudio/conflicted")

Code phases

  1. Data Collection
  1. Data Cleaning
  1. Exploratory Data Analysis

Working Data

Change the label of the data of excel file
from 'Update .gitignore' -> Working Data
