complex NA's match(), etc: not back-compatible change proposal
On 'factor', I meant the case where 'levels' is not specified, where 'unique' is called. > factor(c(complex(real=NaN), complex(imaginary=NaN))) [1] NaN+0i <NA> Levels: NaN+0i Look at <NA> in the result above. Yes, it happens in earlier versions of R, too. On matching both NA and NaN, another consequence is that length(unique(.)) may depend on order.

complex NA's match(), etc: not back-compatible change proposal
This is an RFC / announcement related to the 2nd part of PR#16885 https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16885 about complex NA's. The (somewhat rare) incompatibility in R's 3.3.0 match() behavior for the case of complex numbers with NA & NaN's {which has been fixed for R 3.3.0 patched in the mean time} triggered some more comprehensive "research". I

complex NA's match(), etc: not back-compatible change proposal
With 'z' of length 8 below, or of length 12 previously, one may try sapply(rev(z), match, table = rev(z)) match(rev(z), rev(z)) I found that the two results were different in R devel r70604. A shorter one: > z <- complex(real = c(0,NaN,NaN), imaginary = c(NA,NA,0)) > sapply(z, match, table = z) [1] 1 1 2 > match(z, z) [1] 1 1 3 An explanation of the behavior: With normal

batch job GLM calculations
Hello I want to batch job the calculation of many GLM-models, extract some values and store them in a file. Almost everything in the script below works (read file, extract values and write them to file) except I fail in indexing the GLM with the modelstructure it should run. Running GLM's conventionally is no problem. Conventionally a GLM is calculated as:

complex tangent (PR#7781)
Full_Name: Peter Fortini Version: 2.0.1 OS: Windows 2000 Submission from: (NULL) (65.246.187.164) When the imaginary part of the argument is very large, the complex tangent function returns 0+NaNi. For example, tan(1+1000i)=0+NaNi; it should be 0+1i Easy to fix in complex.c, as the original NaN came from division of sinh and cosh that had reached machine infinity. static void z_tan(Rcomplex

rsync mirroring and hardlink issues
I'm running a mirror of several repositories that are fetched using separate rsync runs. Since some of those repositories are hosting related files, I'm using the hardlink utility[1] in order to save disk space. However, I've noticed an issue that may lead to potential file metadata inconsistencies when using hardlink. Consider the following scenario: - two repositories (rep_a and

retrieve version information for a package?
Hi, I am looking for a way to find out the version information of installed R packages. ex: >library(affy) >SOME_COMMAND_FOR_VERSION(affy) I know I can do either getRversion() or R.Version() could give me the version of R. I assume there must be a way for me to get version information for the add-on paclages,right? Thanks! Yupu

complex NA's match(), etc: not back-compatible change proposal
I am raising this again. With z <- complex(real = c(0,NaN,NaN), imaginary = c(NA,NA,0)) , results of sapply(z, match, table = z) and match(z, z) are different in R 3.4.0 alpha. I think they should be the same. I suggest changing 'cequal' in unique.c such that a complex number that has both NA and NaN matches NA and doesn't match NaN, as such complex number is printed as NA.

R (>= 3.4.0): integer-to-double coercion in comparisons no longer done (a good thing)
Hi, there was a memory improvement done in R going from R 3.3.3 to R 3.4.0 when it comes to comparing an integer 'x' an double 'y' (either may be scalar or vector). For example, in R 3.3.3, I get: > getRversion() [1] '3.3.3' > x <- integer(1000) > y <- double(1000) > profmem::profmem(z <- (x < y)) Rprofmem memory profiling of: z <- (x < y)
