I am new into "programming".

Im doing a study about graduates. I want to verify whether a degree, sex and age highly affect the employment of a person.

So on my data, everything has been converted into number.

Example:
under (employment) STATUS,
1 - working
2 - futher studies
3 - improving skills
4 - waiting for job placement
5 - not working

Under Degree:
1 - Arts and Social Sciences
2 - Science
3 - ICT
4 - Education

Under Sex:
1 - male
2 - female

Can someone please help me on how to do this thing on R?

The teacher expects us to code and make an analysis from the data he gave.

Many thanks.
