Tools for creating homework assignments and solutions using [_RMarkdown_](http://rmarkdown.rstudio.com/).
## Motivation
Writing homework assignments for students in the age of [_RMarkdown_](http://rmarkdown.rstudio.com/) necessitates the creation
of _two_ separate documents -- `assign.Rmd` and `soln.Rmd`.
The goal of `assignr` is to create one document `main.Rmd` that can be broken
apart into the above two documents. Thus, there is no longer a need to
_copy and paste_ between the `assign` and the `soln` documents as all of the
contents are together in one file.
## Installation
`assignr` is only available via GitHub.
To install the package from GitHub, you can type:
```r
install.packages("devtools")
devtools::install_github("coatless-rpkg/assignr")
```
## Usage
To use `assignr`, create an Rmd file named `WXYZ-main.Rmd`, where `WXYZ`
could be `hw00`. Within the file, add to your code chunks one of the following
chunk options:
1. `solution = TRUE`
- to mark a solution
2. `directions = TRUE`
- to indicate directions
When specifying text directions that should not appear in the solution file, use
the latter chunk option, and set the code chunk engine to `asis`, e.g.
````
```{asis name, directions = TRUE}
The goal of the following exercise is...
```
````
Then, in _R_, run:
```r
# Render output
assignr("hw00-main.Rmd")
```
Example Output:
```
hw00
├── hw00-assign
│ ├── hw00-assign.Rmd
│ ├── hw00-assign.html
│ ├── hw00-assign.pdf
│ └── hw00-assign.zip
└── hw00-soln
├── hw00-soln.Rmd
├── hw00-soln.html
├── hw00-soln.pdf
└── hw00-soln.zip
```
Previews of what is contained in each file are shown next.
### Instructor Main
In the main file, denoted as `*-main.Rmd`, all content -- including solutions --
should be placed. As an example of contents, please see the `hw00-main.Rmd`
document that ships with the package.
```r
library("assignr")
file.show(get_example_filepath("hw00-main.Rmd"))
```

# Exercise 1 (Introductory `R`)
```{asis, directions = TRUE}
For this exercise, we will create a couple different vectors.
```
**(a)** Create two vectors `x0` and `x1`. Each should have a
length of 25 and store the following:
- `x0`: Each element should be the value `10`.
- `x1`: The first 25 cubed numbers, starting from `1.` (e.g. `1`, `8`, `27`, et cetera)
```{asis, solution = TRUE}
**Solution:**
```
```{r, solution = TRUE}
x0 = rep(10, 25)
x1 = (1:25) ^ 3
```
