similar to: Invisible doesn't exit function?

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

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 <-

{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

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

Why doesn't this work? x = zoo(1:5, as.Date('2001-01-01')+1:5) x[as.Date('2001-01-05')] x[as.Date('2001-01-05')] = 0 x I think this is especially bad because it doesn't cause an error. It lets you do something to x, but then you can't see x again to see what it did. [[alternative HTML version deleted]]

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() #

Does anyone know if Is there a way to manually install RSPython? I get this error when I try to run the script from my DOS prompt.

** Disclaimer: I'm looking for general suggestions ** I'm sorry, but can't send out the file I'm using, so there is no reproducible example. I'm using read.table and it's taking over 30 seconds to read a tiny file. The strange thing is that it takes roughly the same amount of time if the file is 100 times larger. After re-reviewing the data Import / Export manual I think

I thought the "apply" functions are faster than for loops, but my most recent test shows that apply actually takes a significantly longer than a for loop. Am I missing something? It doesn't matter much if I do column wise calculations rather than row wise ## Example of how apply is SLOWER than for loop: #rm(list=ls()) ## DEFINE VARIABLES mu=0.05 ; sigma=0.20 ; dt=.25 ; T=50 ;

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. A small example called 'test.R': ##### #! /usr/bin/R invisible(capture.output(library(R2HTML))) HTML(summary(as.numeric(scanText(formData$numbers))), file=stdout()) ##### The script gets its input via 'CGIwithR.cgi' and contains the variable "numbers." The 'HTML' output (-> summary() in

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.
