Predicting Income with Social Data - Analyzing Data with R - Linear regression

Hello everyone,

I am trying to use the csv file to do the project with R Studio.
But I have some trouble using the file. The data structure that i am using is not great.
Could someone please help me reading correctly that csv file in R Studio ?

df ← read.csv(“psid_2017.csv”, header = T, sep = “,”, quote= “”)
