Interactive Embedded Plots with Plotly and ggplot2

Largley lifted from this r-bloggers post

install.packages("devtools")  # so we can install from GitHub
devtools::install_github("ropensci/plotly")  # plotly is part of rOpenSci

py <- plotly(username="jflournoy", key="mg34ox914h")  # open plotly connection
# I'll change my key after this, but you can still use: plotly(username="r_user_guide", key="mw5isa4yqp")
# Or just sign up for your own account!

gg <- ggplot(iris) +
    geom_point(aes(Sepal.Length, Sepal.Width,color=Species,size=Petal.Length))

#This looks a little object-oriented like python  

You can embed code like this (which you get from the plotly ‘share’ dialogue):

<a href="" target="_blank" title="Sepal.Width vs Sepal.Length" style="display: block; text-align: center;"><img src="" alt="Sepal.Width vs Sepal.Length" style="max-width: 100%;width: 797px;"  width="797" onerror="this.onerror=null;this.src='';" /></a>
<script data-plotly="jflournoy:16" src="" async></script>
Sepal.Width vs Sepal.Length

You can also directly embed a plotly plot using a code chunk if you set plotly=TRUE for the chunk, and include session="knitr" in the call.

#Set `plotly=TRUE`
py$ggplotly(gg, session="knitr")

There’s a wide world of plotly fun just waiting out there.

    In the last case, i.e. `py$ggplotly(gg, session=”knitr”)` how can one change the width and height of the plot?
