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 ignored: > "aaa\ + bbb" [1] "aaa\nbbb" We could use

...espaces as it's counter-intuitive, misleading and makes it impossible to continue spaces on the next line. None of the languages that I can think of with multiline strings do that as that's way too dangerous.

...a big fan of that syntax but it is widely used. A backslash at the end of the line leads to errors when you accidently put a space after the backslash and the editor doesn't flag it.

The obvious guess would be that Rstudio is attempting something like redirecting output and getting itself confused. However, it is pretty clearly Their Problem, no? Rstudio has their own support infrastructure. -pd > On 26 Jan 2018, at 09:17 , Andreas Kersting <r-devel at akersting.de> wrote: > > Just noticed that this problem only occurs from within RStudio (v1.1.414).

One way to at least emulate something like that is the following. `%+%` <- function(x,y) paste0(x,y) "hello" %+% " pretty" %+% " world" -Mark Op wo 14 jun. 2017 om 13:53 schreef Andreas Kersting <r-devel at akersting.de>: > On Wed, 14 Jun 2017 06:12:09 -0500, Duncan Murdoch < > murdoch.duncan at gmail.com> wrote: > > > On 14/06/2017 5:58 AM, Andreas Kersting wrote: > > > Hi, > > > > > > I would really like to have a way to split long string literals across...

Hi, what is the correct way to specify a C standard in a package's Makevars file? Building a package with e.g. PKG_CFLAGS = -std=gnu11 does work but R CMD check issues a warning: * checking compilation flags in Makevars ... WARNING Non-portable flags in variable 'PKG_CFLAGS': -std=gnu11 (Same for -std=c11.) Thanks! Regards, Andreas Kersting

Hi, Installing a source package on Windows using utils::install.packages() with quiet=TRUE fails, while it works with the default quiet = FALSE. The problem seems to be caused by the fact that when quiet = TRUE, stdout and stderr are set to FALSE when calling "R CMD INSTALL" with base::system2() here:

Hi, I am facing a very weird problem with parallel::mclapply. I have a script which does some data wrangling on an input dataset in parallel and then writes the results to disk. I have been using this script daily for more than one year always on an EC2 instance launched from the same AMI (no updates installed after launch) and processed thousands of different input data sets successfully. I now

Just noticed that this problem only occurs from within RStudio (v1.1.414). Any ideas why?
