R Question

I'm new to R and I'm doing a practice question.

Simulate rolling a fair coin 200 times, then plot a histogram of the data.

I did:

`outcomes <- c("heads", "tails")`

sim_fair_coin <- sample(outcomes, size = 200, replace = TRUE)

hist(table(sim_fair_coin))

It does give me a histogram, but I think I expect a more intuitive histogram. With the X-axis shows "heads" or "tails"; and the Y-axis shows how many times I got for "heads" and "tails".

I believe there is a way to accomplish this in R. Can someone tell me more about it please?

Answer

You can use the `ggplot2`

package as well.

```
x <- as.data.frame(sim_fair_coin)
ggplot(x, aes(factor(sim_fair_coin))) + geom_bar(width=.5)
```
