comment create a comma separated list containing the names of all variables starting with a prefix
Thanks! Both work solutions great. I added an extra line s="${s%?}" in order to remove the last ',' at the end of the string.

comment R function returns unexpected input error
@MrFlick Yes you're right. My guess is that he has a open bracket / parentheses lying around elsewhere in the code.

comment R function returns unexpected input error
To confirm: I can define the function using R 3.1.1 and RStudio 0.98.1079. That said, it is difficult to debug the function without the CSV files. Could you link to the tutorial?

comment Passing variables to a bash script with default values
Thank you for this! This is the best option by far since it doesn't require input arguments to be specified in a given order / can handle multiple input arguments.

comment How to install the CPLEX Python API so that it is accessible in PyCharm 4.0
@xnx Thanks! I had installed it under that location but for some reason it was inaccessible since the installer put it in /Library/Python/2.7/site-packages/cplex/lib/python/cplex (it should have been /Library/Python/2.7/site-packages/cplex/).

comment Late Night Ground Transportation from El Calafate to Puerto Natales / Torres del Paine
I disagree. I'm not looking for a shopping recommendation. I'm asking whether there is a ground transportation option to get from one city to a national park. The question is specific / transportation related and seems to be on topic.

@pnuts Yeap the car rental ends up costing us over $600 + gas so I'm trying to get a price point for the comparison.

comment Driving from El Calafate to Torres del Paine National Park and back?
Thanks for this! One more question: do you think it would be possible to park the car at one of the head trails, do the W trail, and then grab a shuttle back to the parking lot (i.e. avoid having to trek back to the parking lot)?
