P-Value Test Per BodySite (Ultralow against the world!)
========================================================


#reading from table file
```{r,echo=FALSE}
source("~/git/preservation_stats/scripts/distribution_test.R")
feces <- read.csv("~/git/preservation_stats/presv_fig1_data/feces_fig1.csv")
```

Feces
--------------------

generating variables per Preservation Method:

```{r}
feces_ultralow = parse_vector(feces,1)
feces_nitrogen = parse_vector(feces,2)
feces_Phen_CL = parse_vector(feces,3)
feces_Fresh = parse_vector(feces,4)
```

Normality Test with Shapiro-Wilk Test :

```{r,echo=FALSE}
shapiro.test(feces_ultralow)

shapiro.test(feces_nitrogen)

shapiro.test(feces_Phen_CL)

shapiro.test(feces_Fresh)

```

Testing difference significance using Kolmogorov-Smirnov & Wilcoxon Test :
-----------------------------------------------------------------------------

```{r}
ks.test(feces_ultralow,feces_nitrogen)
wilcox.test(feces_ultralow,feces_nitrogen)
wilcox.test(feces_ultralow,feces_nitrogen,paired=T)

ks.test(feces_ultralow,feces_Phen_CL)
wilcox.test(feces_ultralow,feces_Phen_CL)
wilcox.test(feces_ultralow,feces_Phen_CL,paired=T)

ks.test(feces_ultralow,feces_Fresh)
wilcox.test(feces_ultralow,feces_Fresh)
wilcox.test(feces_ultralow,feces_Fresh,paired=T)
```
