similar to: dim(a <- ...) sets invisible flag erronously (PR#587)

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() #

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 <-

Hello, The "[" primitive operator currently has the 'eval' flag set to 0 in src/main/names.c. This means that the result of subsetting, whether R-native or implemented by a method, will never be invisible(). This is a very reasonable default: if the user goes as far as to subset a value, they probably want to see the result. Unfortunately, there also exists at least one

Hi, I stumbled across the following (unexpected for me) behavior after replacing a return() statement in the middle of a function by invisible(). Example: foo <- function() { cat("before\n"); return(); cat("after\n")} >foo() before NULL foo2 <- function() { cat("before\n"); invisible(TRUE); cat("after\n")} >foo2() before after I expected

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

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...

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

Dear all, First, I recently had reasons to read the help page of as.vector() and noticed in the example section the following example: x <- c(a = 1, b = 2) is.vector(x) as.vector(x) all.equal(x, as.vector(x)) ## FALSE However, in all versions of R in which I executed this example, the all.equal command returned TRUE which suggest that either the comment in the help file

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

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

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

Dear alltogether, I want to use CGIwithR in conjunction with R2HTML.

Hi, I'm new to R. I'm trying to do some extreme value theory analysis, looking at the Mean Excess Plot of a series. These 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.

Hello! Unfortunately no. Directory still not listed using ls -la, but I can cd into. I can rename it and it becomes available when I rename it back to the original name it's disappeared again.
