QUESTION
I am currently attempting to run a for loop on about 500 stock tickers and attempting to create a chart for all of them. I have succeeded in doing this but my for loop breaks on this error Error in runSum(x, n) : n = 20 is outside valid range: [1, 5]
I got the stock tickers from BatchGetSymbols library.
Here is my script at the bottom is my for loop:

QUESTION
My aim is to download stock prices using the quantmod library for a large number of ticker symbols (~700) and merge the results in a single dataframe which I will save as a csv file. I have a list of ticker symbols but not all of them are downloadable by quantmod.
So when I pass the list with the ticker symbols to the getSymbols() method, once it encounters a problem with a particular ticker symbol it stops and returns an exception. I am trying to circumvent this behavior with a for loop and the try method, but I fail.
Let's look at some code:

In an ordered dataset, I want to aggregate data until a condition is met, but grouped by a certain key.
To set some context to my question I simplify my problem to the below problem statement:
In spark I need to aggregate strings, grouped by key when a user stops "shouting" (the 2nd char in a string is not uppercase).
Dataset example:

What you want to do is possible, but it may be very expensive.
First, let's create some test data. As general advice, when you ask something on Stackoverflow please provide something similar to this so people have somewhere to start.

...ANSWER
Answered 2018-Feb-22 at 11:17Well, for some reason, Google don't seem to have the day-series price data for Lockheed Martin for 2017 (the ticker symbol your query failed on.)
Also, Google don't like automated queries on financial data: if I run your code I regularly get a response including the text "We're sorry... but your computer or network may be sending automated queries. To protect our users, we can't process your request right now."
If you just want the price data, one simple answer is to use Yahoo instead. Here's a test program (based on your code) that I ran on Yahoo, to check for how many of your symbols it could supply price data:

- You don't use strings correctly; strings must be enclosed in quotes.
- You use a hyphen-separated key in your object which must also be enclosed in quotes, or you'll get a syntax error.
