I'm in need of some R for-loop and grep optimisation assistance.

I have a data.frame made up of columns of different data types. 42 of these columns have the name "treatmentmedication_code_#", where # is a number 1 to 42.

There is a lot of code so a reproducible example is quite tricky. As a compromise, the following code is the precise operation I need to optimise.

I need to map peripheral memory addresses to access the hardware in linux. To make things a bit more generic (aka complicated...) I created a following function:

I am trying to download data gotten from a GET request as a .txt file but I keep getting 'undefined' as the content of the downloaded file. I only need the data portion of the response. A sample response is provided below as well as my redux action, reducer and my export function My action:

I am using the 'esoph' data in R. It is a data frame with records for 88 age/alcohol/tobacco combinations. Here is an excerpt of its data:

.

What I am trying to achieve is to pracitcally remove the alcgp column but keep its data for the ncases and ncontrols columns. So for every entry which has the same age group (agegp) and tobacco group (tobgp) but different alcohol group (alcgp) to add up the values for cases and controls and store them in a single row.

For example row 1, 5, 9, 12 would be merged.

I have a scatterpie plot with pies plotted over x and y axes and a "trend line" connecting them. In the spirit of this answer, I would like to add an annotation over each line to mark the percent increase/decrease between the y-values underlying each adjacent pies.

I'm mystified by this curiosity. (I'm using ConcurrentHashMap rather than ConcurrentSkipListSet because the class doesn't implement Comparable.) I've got plenty of free CPUs on the computer and there is no difference between the classes that are run in the stream (other than random number generation). It's suspicious that the even numbers run first (consistently).

Here are the code and output with nRuns=10. I would expect all 10 threads to fire up and run simultaneously (as they usually do in my other uses of ConcurrentHashMap). Could it be due to some static code in LIBSVM that gets called by SvmCrossValidator? That's all I can think of. It seems to me from a basic Java perspective this stream should launch all 10 processes at once.
