I am analysing sales of a retailer. These sales are related to some vars: var1, var2, var3.., varN

Most of the vars are continuos.

I want to analyze the relationship between sales and the vars. I have made a linear regression with R:

Code:

```
rg<-lm(sales ~ var1 + var2 + var3 + var4, data=sales_2017)
summary(rg)
```

Code:

```
varImp(rg, scale = FALSE)
rsimp <- varImp(rg, scale = FALSE)
plot(rsimp)
```

Thanks in advance. Any advice will be greatly apreciated.
