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

\[ E=mc^2 \]

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

Code

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

Description

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.

Y rating numeric Overall rating
X[1] complaints numeric Handling of employee complaints
X[2] privileges numeric Does not allow special privileges
X[3] learning numeric Opportunity to learn
X[4] raises numeric Raises based on performance
X[5] critical numeric Too critical
X[6] advance numeric Advancement

Lets explore the datasets package with ? command

Conclusion

  • Yay! We were able to type our first equation!
