For completeness, the answer is: you can’t do that from within RStudio. @agstudy has it right – you need to install the newer version of R, then restart RStudio and it will automagically use the new version, as @Brandon noted. It would be great if there was an update.R() function, analogous to the install.packages() function … Read more
For better or worse, this omission is intentional. Relying on objects created outside the document makes your document less reproducible–that is, if your document needs data in the global environment, you can’t just give someone (or yourself in two years) the document and data files and let them recreate it themselves. For this reason, and … Read more
The solution is to explicitly call print() on ggplot object: library(ggplot2) p <- ggplot(mtcars, aes(wt, mpg)) p <- p + geom_point() print(p) ggplot function returns object of class ggplot; ggplot2 works by overloading print function to behave differently on objects of class ggplot – instead of printing them to STDOUT, it creates chart. Everything is … Read more
I have further issues with the previous answer. For that reason, I have extended the answer with further steps (which I experienced currently) as below: Uninstall R, RStudio and RTools from Windows “Programs and Features” menu. Delete everything in folders that was shown after running .libPaths() instruction in R to know where R packages are … Read more
See https://anaconda.org/r/rstudio: $ conda install -c r rstudio Then from command line: $ rstudio (It is how I installed it and it works.)
Perhaps this example due to Winston Chang is helpful: Shiny example app with dynamic number of plots Here is the full example just in case of linkrot: server.R max_plots <- 5 shinyServer(function(input, output) { # Insert the right number of plot output objects into the web page output$plots <- renderUI({ plot_output_list <- lapply(1:input$n, function(i) { … Read more
First of all, I think this question is easier to answer if you limit the scope to the “Compile PDF” button, because the “Knit HTML” button is a different story. “Compile PDF” is only for Rnw documents (R + LaTeX, or think Sweave). I’ll answer your question following the three points you suggested: Currently RStudio … Read more
Rstudio’s behavior Rstudio’s object browser modifies objects it examines in a way that forces copying upon modification. Specifically, the object browser employs at least one R function whose call internally forces evaluation of the object, in the process resetting the value of the object’s named field from 1 to 2. From the R-Internals manual: When … Read more
I had the same problem and went through the same steps as you. The final step to allow starting RStudio through Finder/Spotlight was to link libjvm.dylib to /usr/local/lib: sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib -f flag is added to force overwriting existing file/link
The proper solution is to set environment variable R_LIBS_USER to the value of the file path to your desired library folder as opposed to getting RStudio to recognize a Rprofile.site file. To set environment variable R_LIBS_USER in Windows, go to the Control Panel (System Properties -> Advanced system properties -> Environment Variables -> User Variables) … Read more
