It would break any call to *apply() that used X= to name the first argument. There are currently 3020 such calls in the R code in CRAN. One can avoid the problem

I don?t know if my question is answerable, but it is worth a try. I have a data set that I am trying to analyze in R for a course and the instructions were to get a standard deviation which I already computed in R and use that number and change it to a biased standard deviation?.(I have the two equations and I understand the difference between the two and how the unbiased has the degree of

Is the reason you want a block comment containing code (as opposed to arbitrary text) that you want to be able to easily run the commented out code? If so the 'if()' construct has the advantage that you only need to change code at the start of the comment, not at both ends. The if(FALSE) could be if(isTRUE(getOption("DEBUG_ISSUE_XYZ"))) so you would not even have to change code

R-devel, I discovered a segfault in my R code that boiled down to my incorrect use of the Recall() function embedded within a with() function. Since segfaults are generally bad things, even when it's the user's fault for writing nonsense code, I thought I'd pass along the offending code. I've tested the crash on R 2.11.1 (on Linux and Mac), but not in devel versions of R. HTH,

I am trying to build a function in a context where the environment concept would appear to be useful. But I'm a bit foggy about this concept and would appreciate some pointers and advice. Basically the function I'm building, say foo(x,t), is a function of two variables). Depending on the value of t, foo will return one of the values f1(x), f2(x), ..., fk(x), where each of f1, ..., fk is

OK. I see

Prof. Brian Ripley solved the problem. He wrote: > I was not aware that this works with relative paths for any version > of R. Try using a full path, which always works for me. I tried it using a full path, and bingo! It worked like a charm. Under Unix the relative path also works, but.
