%=>% would have precendence ('order of operations') problems also. A + B %=>% C is equivalent to A + ( B %=>% C) and I don't think that is what you want. as.list(quote(A + B %=>% C)) shows the first branch in the parse tree. The following function, str.language, shows the entire parse tree, as in > str.language(quote(A + B %=>% C)) `quote(A + B %=>%

I suppose it would work, although "=>" is rather a descriptive symbol and less a function. But choosing between quoting: "A + B => C" and a regular function: A + B %=>% C probably quoting is the most straightforward, as the result of the foo() function has to be a string anyways (which is parsed by other functions).

Hi, Field RdMacros was introduced in file DESCRIPTION to allow users to import LaTeX-like macros from other packages. Currently 'R CMD Check --as-cran' gives a NOTE: > Unknown, possibly mis-spelled, field in DESCRIPTION: > ?RdMacros? A small package demonstrating this is available at http://www.maths.manchester.ac.uk/~gb/testRdMacro_0.0.2.tar.gz (and this is the source:

Would making it regular function %=>%, using "%" instead of quotes, work for you?

I thought it was parsed inside the function, but if it's parsed before then quoting is the

In the help page for ?is.integer, there is this function is.wholenumber <- function(x, tol = .Machine$double.eps^0.5) abs(x - round(x)) < tol A quick question: is there a case where this alternative function will not work? function(x) x %% 1 == 0 Best, Adrian -- Adrian Dusa University of Bucharest Romanian Social Data Archive Soseaua Panduri nr.90 050663 Bucharest sector 5

Dear list, I've noticed for some packages the Index file in the help system has a single list of objects (arranged alphabetically), while for other packages this list is offered separately by letters... presumably when the number of help objects is high. Is there a way to manually split the help objects into categories? For example, I would like to have an alphabetic order for the group

Yes, that does have to do with floating point representation. I use this function for these types of comparisons (works with values as well as with vectors): check.equal <- function(x, y) { check.vector <- as.logical(unlist(lapply(x, all.equal, y))) check.vector[is.na(check.vector)] <- FALSE return(check.vector) } See: ?all.equal Hth, Adrian On Tue, Apr 5, 2016 at 2:34 PM,

Dear Bill, I already tried this, and it would have been great as (currently) the sufficiency relation is precisely "=>"... but: foo <- function(x) return(substitute(x)) foo(A => B) Error: unexpected '>' in "foo(A =>" It seems that "=>" is a syntactic error for the R parser, while "<=" is not because it denotes less than or

You could use something like this x <- abs(0.95 - 1) treshold <- 0.05 x < treshold | abs(x - treshold) < 1e-6 ir.

You are right. >= is not as evocative as =>. Perhaps > and < would do? %=>% and %<=% would work.

To do this in C, it would probably be easier and faster to just do the string manipulation directly. Luckily, there are already packages that have done this for you. See an example below using the S4Vectors package. foo2 <- function(mymat, colnms, tilde=FALSE) { chars <- colnms[col(mymat)] lowerChars <- if (tilde) paste0("~", chars) else tolower(chars) chars <-

Dear All, I understand the R CMD checks with only the base package attached, everything else (including the other packages bundled with the base R) should be imported and most importantly declared in the Imports field from the DESCRIPTION file. However, I do use functions from other packages than base (utils, grDevices, stats, graphics), for which it is sufficient to declare importFrom() in the

Thank you for your replies, this actually has little to do with the regular R code but more to signal what in my package QCA is referred to as a necessity relation A <- B (A is necessary for B) and sufficiency A -> B (A is sufficient for B). If switched by the parser, A -> B becomes B <- A which makes B necessary for A, while the intention is to signal sufficiency for B. Capturing in

Thanks Adrian and Thierry (from the previous answer). I was aware of the all.equal function, but there is nothing similar for <= (e.g. all.smallerEqual)? cheers, jo On 05 Apr 2016, at 14:31, Adrian Du?a <dusa.adrian at unibuc.ro<mailto:dusa.adrian at unibuc.ro>> wrote: Yes, that does have to do with floating point representation.
