I also want to change the state column to be in terms of the FIPS code. Just not sure what parameters to use and how to do this since I am new to R.

Here are the parameters given by R:

plot_usmap(regions = c("states", "state", "counties", "county"),
 include = c(), data = data.frame(), values = "values",
 theme = theme_map(), lines = "black", labels = FALSE,
 label_color = "black")

It is unclear exactly what you are trying to achieve without an example, but here is how I was able to convert a column state in a data.frame from the abbreviation to the FIPS code:

> library(usmap)
> df <- statepop[1:5, -1]
> names(df)[1] <- 'state'
> df
# A tibble: 5 x 3
 state full pop_2015
 <chr> <chr> <dbl>
1 AL Alabama 4858979
2 AK Alaska 738432
3 AZ Arizona 6828065
4 AR Arkansas 2978204
5 CA California 39144818
> df$fips <- fips(df$state)
> df
# A tibble: 5 x 4
 state full pop_2015 fips 
 <chr> <chr> <dbl> <chr>
1 AL Alabama 4858979 01 
2 AK Alaska 738432 02 
3 AZ Arizona 6828065 04 
4 AR Arkansas 2978204 05 
5 CA California 39144818 06
