I have installed the following extensions to VSC running on Windows: R, R Debugger, and R Tools. Nevertheless, when R server tries to start, I get this error message: Error in loadNamespace(x) : there is no package called 'languageserver'.
I haven't found how to get and install such package. Thanks for your help.
languageserver is a regular R package. Install it from CRAN with install.packages("languageserver"), like with any other package.

I tried to install R packages using RStudio Package Manager using the following code:
install.packages("dplyr", type = "source")
and
install.packages("dplyr")
and it gives the following error:
Error in install.packages : invalid version specification 'r56550'
What should I do? I tried to google the error but nothing comes up. I have tried to delete and reinstall R and RStudio but i still received the error. I tried to download both the existing binary and the source file and neither ways worked. I tried to install different packages and repeated in both R and Rstudio and nothing worked.
Thank you!
Update 1: I'm using R version 4.0.5 and RStudio version 1.4.1106. I have also downloaded Rtools40 according to the instruction in the following website: https://cran.r-project.org/bin/windows/Rtools/. I'm using Windows. By 'R Manager' I meant the package manager console in RStudio.
Update 2: I'm not sure if there is no network issue or proxy. If I download the packages directly through the CRAN mirror, then it works. But we are trying to download packages in an offline environment, that's why I need RStudio Package Manager.
I am trying to create clustered box plots in R. Everything about my code seems on track, but when I try to run it I get the error warning
"Error in loadNamespace(name) : there is no package called ‘digest’.
When I try to download the package digest in the R package Installer I get a bunch of errors stating that the download of digest failed.
How do I get the digest package, OR is there a way to do clustered box plots without this? Thanks!
I had the same problem with install.packages("digest") on OS10.11.6 (running with the defaults). But it worked by specifying the repos:
install.packages('digest', repos='http://cran.us.r-project.org')
I had a similar error message recently and managed to solve the problem by downloading the tar.gz file directly from the CRAN Repository (see https://cran.r-project.org/web/packages/digest/index.html and download "digest_0.6.15.tar.gz") and then you can install it in RStudio (Tools -> Install Packages -> Install from Package/Archive File).
I am very new to this community.
My aim is to use R for statistical analysis but some errors occurred.
In the first step, I want to load the "XLConnect"-package, in order to open an xlsx-data file, with this code:
install.packages('XLConnect')
library(XLConnect)
Answer was "package ‘XLConnect’ successfully unpacked and MD5 sums checked", after which the following error was given:
Error in library(XLConnect) : the package ‘XLConnect’ doesn't exist.
I also tried the xlsx package, but in this case always got:
Error in -library('openxlsx') : invalid argument to unary operator
or, that the package openxlsx, doesn't exist but some line before it told me the download, installation and check sums were correct!
Additionally, when I try to change the directory in a script, using
getwd(), the following error occurs:
Error in -getwd() : invalid argument to unary operator
When I type it in the console it works.
I downloaded R here: https://cran.r-project.org/bin/windows/base, installed R version 3.4.3 as well as R Studio.
I already looked in the community for some hints but neither could solve my problem:
XLConnect function is not passing argument to system.file
Error when installing XLConnect in RStudio
MY OS is Windows 10, I tried the 32-bit as well as the 64-bit version of R and installed fitting Java-Versions for both verisons( that was the first error that occured but now isn't there anymore).
I tried to load the packages from several CRAN-Mirrors but always the same error occurs (e.g. Germany(Göttingen),Germany(Münster), Belgium(Ghent) or Switzerland ).
Maybe I missed some very basic setting. Is the information I provided enough or do you need more?
Thanks a lot in advance for your support!
Thanks a lot! I installed java 32-bit and 64-bit versions the way it is recommended here: https://www.r-statistics.com/2012/08/how-to-load-the-rjava-package-after-the-error-java_home-cannot-be-determined-from-the-registry/ and I installed the rJava package like this: install.packages("rJava")
library(rJava) and here: https://askubuntu.com/questions/176115/what-is-the-best-way-of-installing-the-r-package-xlconnect I found that this here should work to register R correctly: sudo R CMD javareconf but then I get the error that the console got an unexpected symbol. Or Do you know how to register Java Development Kit in R correctly. I installed jdk-8u161-windows-x64.
Make sure you have Java Development Kit installed and correctly registered in R.
I have made a shiny app which works fine on windows, but when I tried running the same on my ubuntu system the app exists abruptly and I get following error
Loading required package: TTR
Version 0.4-0 included new data defaults. See ?getSymbols.
Error in library(rstudio) : there is no package called ‘rstudio’
After this I tried installing the 'rstudio' package and I am getting the following message:
Warning in install.packages :
package ‘rstudio’ is not available (for R version 3.2.1)
My R version is: 3.2.1 and my RStudio version is: 0.99.467
Note: I am new to ubuntu and the only reason I shifted to ubuntu, was to to use shiny-server.
The rstudio package comes with the installation of RStudio (Desktop or Server). If you need to use the rstudio package, you probably need to install RStudio (Dekstop or Server version).
You can do that from here:
https://www.rstudio.com/products/rstudio/download-server/
That said, I'm not clear on why you would need to load the rstudio package.
That is because there is no package called rstudio (at least not on CRAN anyways). Either there is a typo and you really meant the rstudioapi package, or on your windows system you actually did install a package named rstudio that, however, was distributed from another source other than CRAN. I'd suggest try removing the line library(rstudio) and see if it works.
windows 7 -pro
r studio 0.98.945
r 3.1.1
I am trying to install manipulate:
install.packages("manipulate").
Warning in install.packages :
package ‘manipulate’ is not available (for R version 3.1.1)
is this package not available or is something wrong in my machine or how to get it ?
thanks for all update/help
best regards, Guy Przytula
It's not on CRAN. It's usually installed as part of the RStudio install process. I'd suggest to re-install RStudio.
Another possibility is offered by the RStudio support:
1.) The easiest workaround is to just install the package manually from its location in Program Files - you can zip up the C:\Program
Files\RStudio\R\library\manipulate folder and install it using
install.packages() - this will get the manipulate package installed
and running.
If that doesn't solve your issues, you should post at the RStudio support forum.
