### Creating and Working with Vectors

### Make some vectors 

```{r}
marmots <- c("blue", "green", 4, "yellow")
marmots

# Check class of object 
class(marmots)
```

### Numberic Vectors 
```{r}
pika <- c(12.4, 6.8, 2.9, 8.8, 8.5 )
class(pika)

# Scalar Multiplier
scalar_pika <- 5.2 * pika
scalar_pika

#Be aware of whats getting stored and what is being reported 
```

```{r}
bananas <- c(1, 2, 3, 4)
apples <- c(6, 7, 8)

bananas + apples 
bananas - apples 

#dot product (0)
#bananas %*% apples 
```


### Matrices 
```{r}
#my_values <- seq(from = 1, to = 10, length = 200)
my_values <- seq(from = 1, to = 10,)
my_matrix <- matrix(data = my_values, nrow = 2, ncol = 5, byrow = TRUE)
class(my_matrix)

5 * my_matrix
```

```{r}
glimpse(penguins)
```

```{r}
# a cool update! 
```
