table(chocolate_data_sm$company)
```
```

table(chocolate_data_sm$company_loc,
chocolate_data_sm$cocoa_pct_above_70)
```
```
##
## 0 1
## Australia 14 2

```r
table(mtcars$vs,
mtcars$am)
```
```
##
## 0 1

--
```r

### Making Tables in R with dplyr
+ Main functions: group_by() and count()
+ arrange(), summarise(), mutate(), and ungroup() are also useful
--
```r
chocolate_data_sm %>%
group_by(company) %>%
count()
```
```
## # A tibble: 6 x 2
## # Groups: company [6]
## company n
## <chr> <int>
## 1 Arete 22
## 2 Ocho 6
## 3 Palette de Bine 11
## 4 Sirene 11
## 5 Smooth Chocolator, The 16
## 6 Soma 15
```

### kableExtra: main functions
+ kable() function comes from knitr to create tables
--
+ some parameters I often use:
* col.names - allows you to rename your column names
* caption - adds a caption to the top of your table
--
+ kable_styling() allows many different options to modify tables easily*
--
+ Within this function some things you can do include:
* style the font
* Alternate the color of your rows
* Alter the width and position of your table
.footnote[<i>* = at least more easily than having to code all of the modifications from scratch. I have still screamed at my computer while using kable_styling()</i>]
