README for pieDivPlots

========================================================

A function for making plots where points are pie charts showing compositions. Code from work by Jillian Dunic wrapped into a function by Jarrett Byrnes.

```{r eval=FALSE}

#first install the multifunc library to get the data for the example

library(devtools)

install_github(multifunc, "jebyrnes")

#now install some key packages if you don't have them already

install.packages("plotrix")

install.packages("RColorBrewer")

```

Here's an example using data from Duffy et al. 2003

```{r  fig.height=12, fig.width=16, out.height="600px", out.width="800px"}

source("./pieDivPlot.R")

library(multifunc)

data(duffy_2003)

#which columns have species?

sp <- 18:23

#plot the raw data

pieDivPlot(diversity, Zost_change_mass, sp,

           data=duffy_2003, cex.axis=2, cex.lab=2, radius=0.1)

```

To alleviate overlap, usee the jitterAmount argument as pieDivPlot can call the jitter function to spread out values on the X axis.

```{r  fig.height=12, fig.width=16, out.height="600px", out.width="800px"}

set.seed(697)

pieDivPlot(diversity, Zost_change_mass, sp,

           data=duffy_2003, cex.axis=2, cex.lab=2, radius=0.1,

           jitterAmount=0.2)

```

           

Or you can plot the data after aggregating it and show error bars.

```{r fig.height=12, fig.width=16, out.height="600px", out.width="800px"}

#plot the aggregated data with error

library(plyr)

duffy_2003_Zost <- ddply(duffy_2003, names(duffy_2003)[c(4:5,sp)], summarise,

                       mean_zost_change = mean(Zost_change_mass), se_zost_change = sd(Zost_change_mass)/sqrt(length(Zost_change_mass)))

#for treatments with only one replicate

duffy_2003_Zost$se_zost_change[which(is.na(duffy_2003_Zost$se_zost_change))] <-0

set.seed(697)

pieDivPlot(diversity, mean_zost_change, 3:8, se_zost_change,

           data=duffy_2003_Zost, ylim=c(-8,13), cex.axis=2, cex.lab=2, radius=0.1, jitterAmount=0.3)

abline(lm(Zost_change_mass ~ diversity, data=duffy_2003), lwd=1.5, lty=2, col="red")

```
