For statistical analysis, we usually use `stargazer`

package in R to generate tables with regression analysis results. In order to put those tables into our report, we need to output it in `.tex`

or `.html`

file format. To do so, we need to specify this in the R command:

```
# use stargazer package
library(stargazer)
# build linear models
fit1 <- lm(Y ~ x1)
fit2 <- lm(Y ~ x1+x2+x3)
# output stargazer table
stargazer(fit1, fit2, omit=c("var"),
align=TRUE, type = "text", no.space = TRUE,
title = "Table X", out = "path/fit.tex")
# you can specify the out file extension with html or tex
```

We can also change the `type = "text"`

to `type = "latex"`

or remove the type property, the `tex`

code will be print to the console of R. Please also see the package documentation for details: stargazer.pdf.
