D9-W3-Assignment-Plotly

Generally idea of the assignment

I want to use plotly to create an interactive chart of three selected Internet Companies’ stock price My first screened stock pool: GOOGL(Google), AAPL(Apple), FB(Facebook), yet I encounted some errors.

-Error in data.frame(Date = index(AAPL), AAPL[, 6], FB[, 6], GOOGL[, 6]) : arguments imply differing number of rows: 2494, 1139

And I could not proceed the plot_ly to plot the interactive chart.

This is due to the fact that Facebook’s initial public offering (IPO) on Friday, May 18, 2012. Therefore, Facebook has different data row with other selected companied.

Thus, I modified my stock pool into : GOOGL(Google), AAPL(Apple), YHOO(Yahoo)

Steps to create interactive chart

1-Get StockExchange symbol of selected Stocks

2-Create dataframe with selected stocks

3-Plot interactive chart with selected stocks

    As of 0.4-0, 'getSymbols' uses env=parent.frame() and
 auto.assign=TRUE by default.

 This  behavior  will be  phased out in 0.5-0  when the call  will
 default to use auto.assign=FALSE. getOption("getSymbols.env") and 
 getOptions("getSymbols.auto.assign") are now checked for alternate defaults

 This message is shown once per session and may be disabled by setting 
 options("getSymbols.warning4.0"=FALSE). See ?getSymbols for more details.

[1] "AAPL"  "GOOGL" "YHOO"
