## Makes 3 useful graphs for eda of times series

### Description

This makes 3 graphs to check for serial correlation in data. The graphs are a sequential plot (i vs X_i), a lag plot (plotting X_i vs X_{i+k} where k=1 by default) and an autocorrelation plot from the times series ("ts") package.

### Usage

    simple.eda.ts(x, lag=1)

### Arguments

`x` | a univariate vector of data
`lag` | a lag to give to the lag plot

    ## The function is currently defined as

    ## look for no correlation
    x <- rnorm(100);simple.eda.ts(x)
    ## you will find correlation here
    simple.eda.ts(cumsum(x))
