Rscript “there is no package”

由 可紊 提交于 2019-12-11 11:56:06
问题 I have a script that loads data, processes it, and saves the processed data out. I run it manually without a problem, but it does not work with Rscript. It uses the data.table package, and Rscript cannot find it. I have tried the solution here but get the following error message: Error in eval(expr, envir, enclos) : could not find function ".getNamespace" In addition: Warning message: package ‘data.table’ was built under R version 3.1.1 Error : unable to load R code in package ‘chron’ Error:

问题 How to invoke an R script like the following scan() in Windows? When using either R or Rscript , nothing is read. With Rscript or littler (both on Linux) the script works as expected. # Doesn't work because stdin is already redirected R --no-save < test.R # Works on Linux, doesn't on Windows Rscript test.R # Works on Linux, doesn't exist in Windows r test.R Is there any way at all to achieve this without changing the R code? Perhaps related: Why is there no --interactive switch in Windows?

问题 The binary of Rscript is available but when I try to use it I get: Rscript helloworld.r Rscript execution error: No such file or directory If I just do Rscript, it brings the help/usage for it through. R CMD BATCH is working fine. I tried adding shebang lines in the R code at the start but it didn't work. #!/sys_apps_01/R/R-3.2.0/bin/R #!/sys_apps_01/R/R-3.2.0/bin/Rscript 回答1: It's likely this was installed to (configured for) another directory and then moved after installation. Afterwards

问题 Where can I install Rscript from? I need to run an R script from a php file using exec. However I need to install Rscript first. 回答1: Search the ubuntu repositories. Have you checked the littler package? 回答2: The main package for R is called r-base. For the scripting and command-line front-end see littler (or r-cran-littler in xenial (16.04LTS) and beyond): sudo apt-get install littler 回答3: The answers posted so far are generally useful, but they don't directly answer the question. I recently

问题 I have a Homebrew version of R installed on my Mac (OS X, El Capitan 10.11.5). I've been using rscript successfully for about two weeks now.

问题 Suppose that I have a R script called test.R , stored at C:\ , with the following content: x <- "Hello Stackoverflowers" print(x) To run it via terminal one could simply call: Rscript C:\test.R And as expected, the result will be: However, what I wonder is whether there is a way to run test.R via Windows console but after that staying within the executed R session instead of closing and going back to the console cursor? That is, staying inside the R session instead of going back, in the image

问题 I'm using R, via Rscript and H2O, but H2O is crashing. I want to review the logs, but the R tempdir that contains them seem to be removed when the R session ends (i.e. when the Rscript finishes). Is it possible to tell R/Rscript not to remove the tmp folder it uses? 回答1: A work around for this would be to use on.exit to get the temporary files and save them in a different directory. An example function would be like this: ranfunction <- function(){ #Get list of files in tempdir on.exit
