similar to: ambiguity in the documented return value of Null() from package MASS

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

Bringing up an old topic on a small technicality. In the help documentation on seq. Value: The result is of 'mode' '"integer"' if 'from' is (numerically equal to an) integer and 'by' is not specified. The arguement in seq specifying length also creates "double" which is not obvious in the wording, as "by" is not specified

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

After library(quantreg), ls("package:quantreg") will list all the names you currently export. So cat(ls("package:quantreg"), sep = ", ") will print the list in a form suitable for including

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

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

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

I'm sorry Martin, but I don't understand your point here. I'm assuming that you want the (S3) matrix, x, to be converted to an (S4) Matrix. However, this is not a

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'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 ... WARNING Documented arguments not in \usage in

Is it possible to consider adding .emacs.desktop and .emacs.desktop.lock to files ignored by R CMD build?

I cloned therneau/survival and the installation failed since there is no definition for exported function survfit(). A file seems to be missing - there is survfit0() and survfit0.R but, compared to CRAN, no survfit.R.

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

Windows XP. I have just updated to R 2.11.0 and then run update.packages. In the series of updates, a few will succeed, then I get a failure like package 'mvtnorm' successfully unpacked and MD5 sums checked package 'party' successfully unpacked and MD5 sums checked package 'PBSmodelling' successfully unpacked and MD5 sums checked Error in normalizePath(path) :

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

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

I run checks with R-devel rev. 76756 on several of my packages which use S4, with no ill effects. With the risk of not adding much, it seems that Martin's example, which I repeat below, suggests a crossover between several "signatures" involved here - the signature of the generic, the signature of the method (the argument for setMethod()), and the signature of the function object
