Title: Remove explicit names() calls in granovagg.ds InitializeGgplot

@rmpruzek points out that when `granovagg.ds` is passed data where the column names have more than one word, there is a text-parsing error:

```r
> set.seed(1001)
> test.data <- data.frame(x = rnorm(12), y = rnorm(12))
> colnames(test.data) <- c("Word One", "Word Two")
> granovagg.ds(test.data)

p-value (t-statistic) 0.408
Error in parse(text = x) :

:1:6: unexpected symbol

```

The proposed patch should fix that error.
