Introduction

This is the first time I am showing how to use qmd file to BCE Data Analysis 2025 class.

Show them how to

  1. Install a package (required only once)

  2. Load a package (in every session)

  3. Render/compile a document

Type an equation

\[ y_i = \beta_0 + \beta_1 x_i + \epsilon_i \]

\[ E=mc^2 \]

Code

remove(list=ls())
2 * 4      # multiplication
[1] 8
2 ** 4     # exponentiate 
[1] 16

Lets explore the datasets package with ? command.

?datasets
library(help = "datasets")

From a survey of the clerical employees of a large financial organization, the data are aggregated from the questionnaires of the approximately 35 employees for each of 30 (randomly selected) departments. The numbers give the percent proportion of favourable responses to seven questions in each department.

rating numeric Overall rating
complaints numeric Handling of employee complaints
privileges numeric Does not allow special privileges
learning numeric Opportunity to learn
raises numeric Raises based on performance
critical numeric Too critical
advance numeric Advancement
?attitude
