similar to: Pause in non-interactive mode

Dear R-help members, I have several large data sets from certain simulations I did and now I want to plot the results nicely. I don't know anything about the size of the x and y values in advance. Plotting these values is not a problem. However, I want to add errorbars (errbar in the Hmisc package). 1) For this I'm factoring the data (xdata00 varies from 0 to max(xdata00)) xfactor00 =

Dear R users, I am using function bandplot from the gplots package. To my understanding (viewing the source of bandplot) it calls function plot (add = FALSE) with the same parameters (except for a few removed). I would like to give extra parameters 'xlab' and 'ylab' to function bandplot, but, as can be seen below, that raises warnings (and the labels do not show up at the end).

Dear R-members, Suppose I have a vector with the following strings: V = c("Welfare_Group_1024", "Welfare_Group_1536", "Welfare_Group_160") I want to 'automatically generate a nice y-axis label for this data. A good candidate is something close to "Welfare Group". Is there an easy way to compute something close to the greatest common

Hi Does anyone know if there is a function similar to as.numeric that will extract a numeric prefix from a string as in the following examples? x<-c(3, "abc", 5.67, "2.4a", "6a", "6b", "2.4.a", 3, "4.2a") df.x<-data.frame(Code=x) x.str<-levels(df.x[,1]) # required function result 2.40 3.00 4.20 5.67 6.00 NA Thanks Mike White

Dear All, I'm developing an R application running inside of a Java daemon on multiple threads, and interacting with the parent daemon via stdin and stdout. Everything works perfectly fine except for having some memory leaks somewhere. Simplified version of the R app: while (TRUE) { con <- file('stdin', open = 'r', blocking = TRUE) line <- scan(con,

I am using the RGL library in scripted (non-interactive) mode, but wish to give the data analyst an opportunity to exam the 3D plots. The "data analysts" understand the data, but not R. My intent is to provide simple Windows (XP) batch files that call R and automatically pass scripts to it, and thus permit the analyst to easily access graphics without having to cut and paste commands

Hi: I have also just stumbled into this bug. Unfortunately, I can not change the data my program receives from stdin. My code runs in a larger system and stdin is sent to a Docker container running my R code. The protocol is I read a line, readLines("stdin", n=1), do some actions, send output on stdout, and wait for the next set of data. I don't have control over this protocol, so

Dear all, I would like to draw you attention to this question on SO: https://stackoverflow.com/questions/50372043/readlines-function-with-new-version-of-r Based on the OP's code I used the script ####################################### create_matrix <- function() { cat("Write the numbers of vertices: ") user_input <- readLines("stdin", n=1) user_input <-

Hello, I am trying write a script that includes a prompt for user input using readlines() and was told that folks at R-devel might be able to help. I am running into the problem that when I run readlines() as a single line the prompt works perfectly, but when I try to run a block of code which includes the readline function, the script doesn't wait for the user input. I have seen this

Hi Michael: I can confirm Martin's comment. I tested my software with r-devel (r74914) and it works, while with r-patched (r74914) it does not work (it hangs, as it did in R 3.5.0). I apologize for it taking so long for me to test this, but is there any chance this fix could make into R 3.5.1? Thanks. Jen.

Hi, is it intended that one cannot install packages in non-interactive mode, without explicitly setting a CRAN mirror (see below)? Couldn't a default mirror be used in that case? Thank you. Bests, Renaud $ Rscript --vanilla -e "install.packages('whatever')" Installing package into '/home/renaud/R/x86_64-pc-linux-gnu-library/3.0' (as 'lib' is unspecified)

DeaR list, let us assume we have stored a couple of functions in 'test.R'. Is it possible to run R CMD BATCH "test.R" or R --file="test.R" interactively and if yes how? A better formulated question sounds like this: how can I source "test.R" interactively OUTSIDE R? Another clarification try: I want to fix the "<my-command> in non-interactive

Hi I've been stumbling over a simple issue that undoubtedly has an easy solution. I need to have some way for a user to enter some values into a data frame which R will then work on. I know that data entry should ideally be done otherwise and I should use R only for the computation, but R's data manipulation abilities makes it efficient for me to write the entire code in it. When I ran

Hi, i want to use R as a filter in a Unix-like way. So i want to start it with producerTool | R --no-save --no-restore --slave < Rscript | anotherConsumerUnixTool inside the Script i put the results to stdout, works fine, but how to read in from stdin? Its obvious that i have to source the Rscript in a different way. Any Hints? My second question is, if there is a possibility to use

Hello, I have this script which will be invoked as Rscript a.r < a.r a.r follows #!/usr/bin/Rscript --vanilla f=file("stdin") while(TRUE){ y=readLines(f,n=1,warn=TRUE) if(length(y)==0) break else print(y) } But it only reads one line from a.r How can I read line by line from standard input? Thank you Saptarshi

Bug 17432 (https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17432) is still a problem when using pipes for IPC. The bug is evident when calling R from another process and trying to communicate via StdIn. R will buffer the input and not read lines until the buffer is exceeded or StdIn is closed by the sending process. This prevents interactive communication between a calling process and a

Michael: I don't see any comments on Bug 17432 ( https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17432) later than June 1, 2018. Would you please supply a link pointing to the followup to this discussion on bugzilla? Thanks.
