Is k equivalent to k:k ?
Hi, I wonder if the following (apparent) inconsistency is a bug or feature. Since scalars are simply vectors of length one I would think that a and a:a produce the same result. For example, > identical(4.01,4.01:4.01) [1] TRUE However, identical(4,4:4) [1] FALSE and > identical(4.0,4.0:4.0) [1] FALSE A closer look reveals that the colon operator produces objects

Rd parser throws error for user macros invoked with empty argument
While on the topic of Rd macro arguments, it seems that if a multiline argument is supplied, the lines after the first are silently ignored: f <- tempfile() mac6 <- "\\newcommand{\\mac6}{mac6: #1}" cat(mac6, "\\mac6{2*3 2+2 sin(pi) }\n", file = f) rd <- tools::parse_Rd(f) > rd mac6: 2*3 --- Georgi Boshnakov -----Original Message----- From: Tomas Kalibera

incomplete results from as.character.srcref() in some cases involving quote()
Hi, The result of as,character() on 'srcref' objects doesn't have the closing ')' in some cases involving 'quote': > e4 <- quote({2+2}) > class(attr(e4, "wholeSrcref")) [1] "srcref" > as.character(attr(e4, "wholeSrcref")) [1] "e4 <- quote({2+2}" As a result printing the object also lacks it and gives an

slight anomaly in formals<- ? (PR#9758)
Hi, The R input/output after the following paragraph is from a session with version.string R version 2.4.0 Patched (2006-11-23 r39958). The last element, x$c, of x has no value and after the assignment of x to the formals of f, x$c does not become a formal argument of f. The second assignment does the job. It seems that x$c actually becomes the body of f after the first assignment. There is no

> ... reports that the fortran names of all the registered fortran functions are ?undocumented objects?... Those symbols should not be exported. In quantreg v5.33, NAMESPACE has 'exportPattern(".")'. Maybe it is a good time to remove that and export explicitly the symbols that are meant for export. Georgi Boshnakov ------------------------------ Message: 6 Date: Fri, 28

Rd parser throws error for user macros invoked with empty argument
Bug or feature? I get the following error from parse_Rd() when a user Rd macro (including system ones) is invoked with empty argument {}, eg \mymacro{}: Error in tools::parse_Rd(fn) : Value of SET_STRING_ELT() must be a 'CHARSXP' not a 'NULL' A full example is further below with the system macro \CRANpkg{}. In this example it doesn't make sense to use empty argument but

disappearing paragraphs in html rendering of text from Rd macros
Recent changes in R-devel seem to change the HTML rendering of text returned by Rd macros, in that now empty lines do not cause paragraphs to end (the empty lines are kept but <p> tags are not set). As a result, multiple paragraphs are output as a single one. A complete example Rd file is at: https://github.com/GeoBosh/reprexes/blob/master/disappearingParagraphs/a.Rd rendered (2018-10-28)

R CMD check does not report redundant '...' argument described in Rd File
R's checks seem to be failing to notice a redundant '...' argument described in the documentation of a function. Consider a function: fun_3 <- function(arg1, arg2, arg3) { "I am fun_3" } If its documentation describes an argument, say 'dummy', R check reports something like: * checking Rd \usage sections ...

bug in na.contiguous? Doesn't give the first tied stretch if it is at the start
Hi. The description of na.contiguous says: "Find the longest consecutive stretch of non-missing values in a time series object. (In the event of a tie, the first such stretch.)" But this seems not to be the case if one of the tied longest stretches is at the start of the sequence/series. In the following example, there are three stretches of length 3, so I expect the result

. Possible issue with R-tools on Windows
I encountered this issue a couple of months ago and resolved it by installing Rtools in the default directory C:\Rtools, see below for details. I didn't have time to prepare a proper error report and in fact suspected that I may be messing up something. I tracked down the error by installing from the command line, rather than with install.packages(). On Windows I keep multiple versions of

ambiguity in the documented return value of Null() from package MASS
Hi, Function Null from package MASS seems to return a matrix with zero columns and the expected number of rows when the null space of the argument contains only the zero vector, e.g. > library(MASS) > diag(nrow=3) [,1] [,2] [,3] [1,] 1 0 0 [2,] 0 1 0 [3,] 0 0 1 > Null(diag(nrow=3)) [1,] [2,] [3,] But the documentation of Null seems to imply that
