|-
|| 00:01
|| Welcome to this tutorial on '''Working directories in RStudio.'''

|-
|| 00:07
|| In this tutorial,''' '''you will learn about:

|-
|| 00:11
|| '''Working directories '''in '''Rstudio'''

|-
|| 00:15
|| How to read and store '''csv '''files in '''R'''

|-
|| 00:20
|| To understand this tutorial, you should know:

|-
|| 00:24
|| '''R''' and '''RStudio'''

|-
|| 00: 27
|| Basic commands of '''R'''

|-
|| 00:30
|| If not, please locate the relevant tutorials on '''R''' on this website.

|-
|| 00:37
|| This tutorial is recorded on

|-
|| 00:41
|| '''Ubuntu Linux OS 16.04'''

|-
|| 00:46
|| '''R '''version''' 3.2.3 '''

|-
|| 00:50
|| '''RStudio''' version''' 1.1.456'''

|-
|| 00:56
|| Install '''R''' version '''3.2.0''' or higher.

|-
|| 01:02
|| We will use the '''captaincy data set '''which we created earlier in this series.

|-
|| 01:08
|| Download this data set '''CaptaincyData.csv''' from the '''Code files''' link of this tutorial.

|-
|| 01:18
|| I have downloaded and moved this '''data set''' to the folder '''myProject''' on my '''Desktop'''.

|-
|| 01:27
|| I shall set this folder as my '''Working Directory.'''

|-
|| 01:33
|| Remember we had created two scripts, '''myfirstscript.R''' and '''mysecondscript.R'''

|-
|| 01:43
|| Both were saved in the folder '''myProject''', on the '''Desktop.'''

|-
|| 01:49
|| '''R''' always points to a default '''directory''' on our computer

|-
|| 01:55
|| This '''directory''' is where '''R''' will look, by default, for files you ask it to load.

|-
|| 02:03
|| We will find out what our current '''Working Directory''' is.

|-
|| 02:07
|| Let us switch to '''RStudio'''.
|-
|| 02:12
|| In the '''Console''' window, type '''getwd parentheses''' and press '''Enter'''.

|-
|| 02:21
|| The current '''Working Directory''' is shown in the '''Console'''.

|-
|| 02:26
|| Note down the '''directory path'''.

|-
|| 02:29
|| Now, we will learn how to set our '''Working Directory'''.

|-
|| 02:35
|| I will set the folder '''myProject''' on my '''Desktop''' as my '''Working Directory'''.

|-
|| 02:43
|| I am maximizing the '''Files and Plots''' window of RStudio.

|-
|| 02:49
|| At the top of the '''Files and Plots''' window, click on the '''Files '''tab.

|-
|| 02:57
|| Go to the upper right corner of the same window.

|-
|| 03:02
|| Below the refresh icon, click on the button with three dots.

|-
|| 03:09
|| '''Go To Folder''' window appears.

|-
|| 03:13
|| Select the folder which you want to make as your '''Working Directory '''and''' '''click''' Open'''.

|-
|| 03:21
|| I am selecting '''myProject''' located on my '''Desktop'''.

|-
|| 03:27
|| Under '''Files''' tab, you can see that the two '''scripts '''created earlier, have been loaded.

|-
|| 03:35
|| Now, below the '''Files''' tab, click on the '''More''' button with the blue gear symbol.

|-
|| 03:43
|| From the dropdown menu, select the '''Set As Working Directory''' option.

|-
|| 03:50
|| Now this folder is set as your '''Working Directory.'''

|-
||03:56
|| You may verify this by looking at the '''Console'''.

|-
|| 04:00
|| Now, I am minimizing the '''Files and Plots''' window.

|-
|| 04:05
|| There is one other way to set the''' Working Directory '''also.

|-
|| 04:11
|| In the '''Console''', type '''setwd. '''

|-
|| 04:15
|| Now, inside parentheses, type the desired '''folder path '''within double quotes.

|-
|| 04:23
|| Press '''Enter'''.

|-
|| 04:25
|| Now, we will learn how to read and store a '''csv '''file called '''CaptaincyData.csv.'''

|-
|| 04:34
|| We shall declare a '''variable captaincy''' to store '''CaptaincyData.csv'''.

|-
|| 04:41
|| In the '''Console '''window, type '''captaincy''' space '''equal''' sign space '''read.csv'''

|-
|| 04:50
|| Now, '''CaptaincyData.csv''' inside double quotes in '''parentheses '''and press '''Enter'''.
|-
|| 05:01
|| '''read.csv function '''is used to read a file and to create a '''data-frame''' from it.

|-
|| 05:10
|| Now, we use '''View function''' to see the stored '''data frame'''.

|-
|| 05:16
|| In the '''Console '''window, type '''View captaincy '''in '''parentheses '''and press''' Enter. '''

|-
|| 05:25
|| The contents of '''captaincy data frame''' appears in the '''Source''' window.

|-
|| 05:31
|| I am maximizing the '''Source''' window to see the '''captaincy''' data set.

|-
|| 05:37
|| This brings us to the end of this tutorial. Let us summarize.

|| 05:44
