[Rd] duplicated factor labels.

Dear R devel I've been wondering about this for a while. I am sorry to ask for your time, but can one of you help me understand this? This concerns duplicated labels, not levels, in the factor function. I think it is hard to understand that factor() fails, but levels() after does not > x <-

Re: [Rd] [bug] droplevels() also drop object attributes (comment…)

In R devel r72789, the added part in 'factor' documentation (factor.Rd) is the following. Undocumentedly for a long time, \code{factor(x)} loses all \code{\link{attributes}(x)} but \code{"names"}, and resets \code{"levels"} and \code{"class"}. In the code of function 'factor', names(x) is

Hello bioc developers, The same error appeard for RTCGA as the one year ago. It is impossible to find dependent RTCGA.rnaseq package. http://bioconductor.org/checkResults/release/bioc-LATEST/RTCGA/tokay2-checksrc.html This is the only platform that has such an error. It appeared frequently

Re: [Rd] spurious warning in ave()

You can avoid the warnings and the unneeded calls to FUN by adding drop=TRUE to the call to ave(), since all of its ... arguments are passed to interaction (I think). In TERR we dealt with this problem by adding drop=TRUE to ave's argument list and we pass ... and drop=drop to interaction. I'm

Re: [Rd] [WISH / PATCH] possibility to split string literals across multiple lines

I don't think it is reasonable to change the parser this way. This is currently valid R code: a <- "foo" "bar" and with the new syntax, it is also valid, but with a different meaning. Or you can even consider a <- "foo" bar %>% func() %>% print() etc. I like the idea of string literals, but

Re: [Rd] [WISH / PATCH] possibility to split string literals across multiple lines

If you are changing the parser (which is a major change) you might consider treating strings in the C/C++ way: char *s = "A" "B"; means the same as char *s = "AB"; I am not a big fan of that syntax but it is widely used. A backslash at the end of the line leads to errors

As I recall this has been discussed at least a few times (unfortunately I'm traveling so can't check the references), but the justification was never satisfactory. Personally, I wouldn't mind string continuation supported since it makes for more readable code (I had one of my packages raise a

Hi Mark, I got you. I just pointed out the obvious to illustrate why your emulation didn't eliminate the need for the real thing. I didn't mean to imply you weren't aware of this, even though it may seem so. Sometimes I'm not 100% aware of the subtleties of the English language. This seems one of

Re: [Rd] [WISH / PATCH] possibility to split string literals across multiple lines

I know it doesn't cause construction at parse time, and it was also not what I said. What I meant was that it makes the syntax at least look a little as if you have a line-breaking character within string literals. Op wo 14 jun. 2017 om 14:18 schreef Joris Meys : > Mark,

Re: [Rd] [WISH / PATCH] possibility to split string literals across multiple lines

Mark, that's actually a fair statement, although your extra operator doesn't cause construction at parse time. You still call paste0(), but just add an extra layer on top of it. I also doubt that even in gigantic loops the benefit is going to be significant. Take following example: atestfun <-

Re: [Rd] [WISH / PATCH] possibility to split string literals across multiple lines

Having some line-breaking character for string literals would have benefits as string literals can then be constructed parse-time rather than run-time. I have run into this myself a few times as well. One way to at least emulate something like that is the following. `%+%` <- function(x,y)

[Rd] [WISH / PATCH] possibility to split string literals across multiple lines

Hi, I would really like to have a way to split long string literals across multiple lines in R. Currently, if a string literal spans multiple lines, there is no way to inhibit the introduction of newline characters: > "aaa + bbb" [1] "aaa\nbbb" If a line ends with a backslash, it is just
