...;after\n")} >foo2() before after I expected invisible to have the same behavior as return, namely immediately return execution to the calling environment. I rechecked ?invisible and ?return and here I read in section 'See Also' [...] 'invisible' for 'return(.)'ing _invisibly_. Do I just misunderstand what this implies? Put another way what is the intention behind invisible() continuing until the last statement before returning? ?invisible does not hint at this.

Evaluate the following example to get the behavior : --- anybody: patch ? --- tst.i <- function(x) { if(missing(x)) return(invisible()) else if(!is.numeric(x)) stop("x must be numeric") ## else invisible((x+3)^2) } tst.i()#-- should NOT print anything !! print(mode(tst.i()))#--gives "NULL" both in S-plus 3.4 and R 0.60 tst.i(1)# nothing (ok in R and

Suppose we have a function such as the following F <- function(f, x) f(x)+1 which runs function f and then transforms it. I would like the corresponding function which works the same except that unlike F returns an invisible result if and only if f does. Is there some way of determining whether f returns an invisible result or not? Thus we want this: f <- function(x) x g <-

###Dear R users ###I have been using SensoMineR package from CRAN for most of my work in sensory data analysis and from my usage experience, I encountered some areas for improvement and considered ###modifying the function in SensoMineR package for my personal use. I felt that it could be useful to share this to the community for enabling adoption by other users where they might require a

As part of my 3 day training course on Rails, I hand out a 24 page "short reference" of Rails. It''s collection of the most used calls, methods, functions across a wide range of Rails functionality. I have released it under a Creative Commons license, so feel free to grab it and use it and improve it. It''s a bit rough around some of it''s edges, and I

{Nothing really harmful; R 1.1.0} dim(.) sets (or doesn't clear) the ``invisible flag'' for printing in certain circumstances: > dim(a <- cbind(1)) > does *not* print as it should : > dim(a) [1] 1 1 --- Question to the real "hackers" : How can I check this using R code alone (not using files), i.e. (how) can I ask an R expression if its

Dear R Core devs, I wonder if it makes sense to make function file.rename return invisible? This is not a big issue, but when running in RMarkdown or knitr, this function will print results. I have to manually call invisible to hide the output from showing in the final document: ```r invisible(file.rename(...)) ``` Otherwise knitr will print: ``` file.rename(...) #> TRUE ``` If this

...e are the commands I type to get the plot: x=read.table("data.txt",header=T) goa=(x[,3]) meplot(goa) I can see the plot, but I would like to see the values of the x and y axis. According to this page (http://rss.acs.unt.edu/Rdoc/library/VGAM/html/meplot.html), "A list is returned invisibly with the following components. threshold The x axis values. meanExcess The y axis values. Each value is a sample mean minus a value u. " So my question is, how can I see (or even export) threshold and meanExcess? Thanks, F -- View this message in context: http://r.789695.n4.nabble...

I thought that invisible works like return() However, it appears that it doesn't exit a function. Is it supposed to work this way? funInvisible = function(){ invisible(10) cat('I was not expecting this to print\n') cat('because it occurs after the invisible return\n') } funInvisible() funVisible = function(){ cat('start of function\n')

Hi Team, After performing the gluster clean up and again doing gluster configuration the sub directories become invisible. Even after they are present the directories are invisible. If I create a new directory by the same name it will say the directory already exists. Thanks & Regards, Sangeeta Ramapure -------------- next part -------------- An HTML attachment was scrubbed...

I noticed an issue where readChar does not return the correct value after a call to readline. It appears that readChar is not aware of the buffering, so it reads from the end of the buffer, rather than the current position in the file. This is a significant change of behavior from R-3.4.4. Below is a test case that I used to home in on the problem. --- p<-"test2.txt"

can you please describe a bit more about the steps taken to clean up and re-configure gluster?

...ue visibly. This means that if you for instance add: Sys.setlocale("LC_COLLATE", "C") to your .Rprofile file, it will print: [1] "C" at startup. The workaround is to wrap the call in invisible(), but I'd argue that any "setter" function should return invisibly. Some more details: > withVisible(Sys.setlocale("LC_COLLATE", "C")) $value [1] "C" $visible [1] TRUE > withVisible(Sys.setenv(FOO = "C")) $value [1] TRUE $visible [1] FALSE /Henrik

Hello! We are running distributed volume that contains 7 bricks. Volume is mounted using native fuse client. After an unexpected system reboot, some files are disappeared from fuse mount point but still available on the bricks. The way it disappeared confusing me a lot. I can't see certain directories using ls -la but, at the same time, can cd into the missed directory. I can rename the

Hi, My samba server "linux-1" (samba-3.0.2-7.FC1) has suddenly become invisible from all windows client. The samba server is a member of the "RASKNO" workgroup and was visible when browsing the workgroup from windows clients a few weeks ago. The weird thing is that it is now invisible. The only changes has been regular updates of FC1. The symptoms is that I can search for

I think this is a more problematic buglet in (implicit/explicit) ``invisible behavior''). Try this (all versions of R from 0.49 to 0.60): test0 <- function() c(1,2) test <- function(two = FALSE) c(1, if(two) 2) testR <- function(two = FALSE) return(c(1, if(two) 2)) test0()# 1 2 as it should test() #

Dear R devel list I was wondering whether zip() contains a windows specific call to system(), as the argument "invisible" seems to be windows specific, yet is used anytime by zip: invisible(system2(zip, args, invisible = TRUE)) Indeed, calling zip() on Linux results in a warning message: > file.create("try") [1] TRUE > zip("try.zip", "try")
