[R] plot problem

Hi, I am just curious why does this happen: I use Goldencheetah to analyse my run. It can call R to do further analysis. I run into interesting problem (for me at least). If I plot data using plot(d$time,d$heart.rate) everything is OK if I use plot(d$heart.rate~d$time) I got error: Error in

[R] Possible Improvement to sapply

2018-03-13 Thread Doran, Harold
While working with sapply, the documentation states that the simplify argument will yield a vector, matrix etc "when possible". I was curious how the code actually defined "as possible" and see this within the function if (!identical(simplify, FALSE) && length(answer)) This seems superfluous

Martin In terms of context of the actual problem, sapply is called millions of times because the work involves scoring individual students who took a test. A score for student A is generated and then student B and such and there are millions of students. The psychometric process of scoring

Could your code use vapply instead of sapply? vapply forces you to declare the type and dimensions of FUN's output and stops if any call to FUN does not match the declaration. It can use much less memory and time than sapply because it fills in the output array as it goes instead of calling

Quite possibly, and I’ll look into that. Aside from the work I was doing, however, I wonder if there is a way such that sapply could avoid the overhead of having to call the identical function to determine the conditional path. From: William Dunlap [mailto:wdun...@tibco.com] Sent: Tuesday,
