[Rd] read.table error upon package installation (PR#8230)

Upon upgrading to R 2.2.0 on my Windows box, I found that one of my packages no longer compiled, giving this error: Error in read.table(zfile, header =3D TRUE) : more columns than column names Execution halted After removing every line of code from my package and still not being able to c

Re: [Rd] as.character(list(NA))

Also perhaps a surprise that the behavior depends on the mode of the NA. > is.na(as.character(list(NA_real_))) [1] FALSE > is.na(as.character(list(NA_character_))) [1] TRUE Does this mean deparse() preserves NA-ness for NA_character_ but not NA_real_? -Original Message- From: R-devel [

[Rd] prettyNum digits=0 not compatible with scientific notation

R developers, Seems I get a bad result ("%#4.0-1e" in particular) when trying to use prettyNum digits=0 with scientific notation. I tried on both my Linux box and on an online R evaluator and saw the same problem, so it's not limited to my box at least. I see the problem in both R 3.5.3 and R 3.

[Rd] Matrix package breaks as.matrix method

Hi, The Matrix package and the as.matrix method do not seem to be compatible inside of a package. Here's an example. I've created a simple package "mat" that defines an eponymous class and as.matrix method on that class. All is well, unless that package has the Matrix package in its Depends or

Re: [Rd] non-infectious license for R package?

I have no direct experience in this regard, but this FAQ seems to answer your question. https://www.gnu.org/licenses/gpl-faq.en.html#IfInterpreterIsGPL I read this to mean that the answer may be different depending on whether your code links against R libraries or simply uses R as an interprete

Re: [Rd] Very hard to reproduce bug (?) in R-devel

Winston, I had a similar experience to you tracking down an insanely difficult bug in my R code that "disappeared" whenever slight changes were made to the script (e.g. like adding cat() statements). In my case, it coincided with my over-eager compilation of R and its library stack, as I was als

[Rd] Allow dot in RHS of update.formula's old formula

Feature request: I want to use update.formula to subtract an intercept (or other) term from a formula with a dot on the RHS. However, as this causes an error, I propose a patch below. Thus, I want: > update.formula(y ~ ., ~ . -1) [1] y ~ . - 1 Instead I get this error: Error in terms.formula(t

Re: [Rd] 'ordered' destroyed to 'factor'

Hi, It's been my experience that when you combine or aggregate vectors of factors using a function, you should be prepared for surprises, as it's not obvious what the "right" way to combine factors is (ordered or not), especially if two vectors of factors have different levels or (if ordered) ar

Re: [Rd] 'gsub' not perl compatible?

Hi Jean-Luc, FWIW, you're pointing out a common discrepancy between regex parsers, which is whether or not a regex parser advances after finding both a zero-length match and a non-zero-length match. I think this article is especially helpful for understanding the nuances here, particularly the
