```
Installation
------------
```julia
Pkg.clone("https://github.com/alexhallam/Stemplot.jl")
```
Getting Started
----------------
This package has the function `stemplot` which is used to generate
simple stemplots in Julia.
Description
----------------
Draws a stem leaf plot of the given vector `v`.
Usage
----------------
`stemplot(v)`
```
function stemplot(v::AbstractVector;
scale=10,
divider::AbstractString="|",
padchar::AbstractString=" "
)
```
Arguments
----------------
-**`v`** : Vector for which the stem leaf plot should be computed
-**`scale`**: Set scale of plot. Default = 10. Scale is changed via orders of
magnitude common values are ".1","1"."10".
-**`divider`**: Symbol for break between stem and leaf. Default = "|"
-**`padchar`**: Character(s) to separate stems, leaves and dividers. Default = " "
Examples
----------------

julia> stemplot(rand(1:100,80))

Or Julia's fancy emoji "smile" you can get by typing `\:smile` + `Tab`
```julia
julia> stemplot(randn(50),scale = 1, divider = "😄")
-2 😄 0
-1 😄 0000000000
-0 😄 000000000000
0 😄 000000000000000000000
1 😄 000000
Key: 1😄0 = 1
The decimal is 0 digit(s) to the right of 😄
```
TODO
-------
- [ ] Create type for stemplot so that it can be updated/refreshed with `stemplot!()`
- [ ] Add `trim::Bool` parameter - round down by base *`scale`* to reduce digits
- [ ] Create method for back-to-back stem plots which can be useful for comparing
distributions:
```julia
julia> stemplot(dataset1, dataset2)
99832 | 0 | 12339
210 | 1 | 0012334
| 2 | 89
6600 | 3 | 00136
```
