Since I've developed my R into 3.6.1, mailR package is not working anymore getting this error: there is no package called ‘R.utils’.
Installing this package does not work either. Is there any way to fix it?
The package mailR depends on rJava package.
"It’s a wrapper around Apache Commons Email, an email library built on top of the Java Mail API. Due to this, mailR has a dependency on the rJava package, a low-level interface to Java VM.", source.
Therefore, you need to install the package rJava in order to use mailR, and you need to have Java Runtime Environment on your operating system in order for rJava to work properly. I recommend using either Oracle's or OpenJDK.
After you have these installed, you need to include both libraries:
library(rJava)
library(mailR)
Note that you might run into an error that says Error in library(mailR) : there is no package called ‘mailR’ even though you have it installed. In this case, restart your PC, run R Studio again and then include the library, and there should be no issues.

I'm having a bit of a pickle right now with the package tidyverse, that I need for an assignment on layering maps. I tried installing the package using install.packages("tidyverse") and install.packages ("tidyverse", dependencies = TRUE) but when I ran library(tidyverse) it wasn't installed. I searched online and found that I had an older version of RStudio IDE so I uploaded the latest version (1.3.1056).
After installing the newest version, I reinstalled the package but R tells me the following:
"Rtools is required to build R packages but is not currently
installed".
So, I did it, but the R tells me Rtools package is not available for R version 3.5.3.
What can I do to use tidyverse?
It could be a permissions issue, try setting the directory for where you install R packages/libraries on your computer using libpaths. I have to do this on my work laptop because the university has it set up to store things like this in a tempporary directory on the remote server which isn't desirable.
.libPaths("C:/R")
.libPaths()
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.
In trying to install package "RevoScaleR", I get the following error. I have tried installing this package with various versions of R but get the same error every time. Does anyone have any idea why?
install.packages("RevoScaleR")
Warning in install.packages :
package ‘RevoScaleR’ is not available (for R version 3.1.2)
Any help is appreciated.
Just to update this post,to install the RevoScaleR package you need to install Microsoft R client, see here for details:
https://www.blue-granite.com/tutorials/sql-server-r-services
R Client includes the ScaleR (rx[…]) functions in the RevoScaleR package. I don't believe this package is open source so isn't available on cran, install.packages() therefore won't work.
The RevoScaleR package is only available if you install the Microsoft R Client or if you use Microsoft RStudio Server via Azure. After you install this you don't need to do install.packages("RevoScaleR") for it is already installed.
R Studio will automatically have the R version [64-bit] C:\Program Files\Microsoft\R Client\R_SERVER under "Global options"
The link below gives more detail information about Microsoft R client. Once you install Ms R client and update the R-studio path to the R client you don't need to install 'RevoScaleR' anymore, it comes pre-installed with Microsoft R client. Read the link fore more.

I am not sure what R version you are currently using but the latest stable version is 3.1.2. If the package installation warning is telling that the package you're trying to install is not available, that basically means that the package developer has not yet made a version of the package that is compatible with the R version you're currently running.
If you really need to use this package (if your work heavily depends on it and you are on some kind of deadline) I would advise to install an earlier version of R (like 3.1.1 or 3.1) and do your work with it.
I would also suggest that you reach out to Revolution Analytics, as suggested by Andrie.
Thanks!
You just have to set the propper CRAN repos:
options("repos" = c(CRAN = "https://mran.microsoft.com/"))
and then
install.packages("RevoScaleR")
will run properly.
I installed a R package as suggested by How do I install an R package from source?, using R CMD INSTALL [my_pkg_path.tgz]. Package sources are downloaded from r-project.org, e.g., http://cran.r-project.org/web/packages/fields/index.html
However, when I try to load the package using say library(fields), I got the error that complains the package are built for universal-apple-darwin:
Error: package ‘fields’ was built for universal-apple-darwin9.8.0
Guess it's something to do with architecture, but no idea how to resolve it. Any idea? Thanks.
It looks like you downloaded the package's Mac OSX binary file, which usually ends in .tgz - try downloading the package source (usually something ending in .tar.gz) and installing the package again.
Depending on what your operating system is, you may need an additional set of software before you can install packages from source. If the above suggestion doesn't work, would you provide some information about the OS, for example from sessionInfo()?
Currently, on my R 2.10.1 installation on Windows XP,
capabilities()["cairo"]
returns False. Loading the package cairoDevice fails with the message "LoadLibrary failure" however the shared library "C:/Programme/R/R-2.10.1/library/cairoDevice/libs/cairoDevice.dll" is there. Any ideas how I can make cairo work on windows?
The capabilities refers to the R binary and its compile-time options.
The add-on package could or should still work. You may need to install the Gtk2 libraries this depends upon. This is the same for other packages using RGtk2 such as, say, Rattle. See eg this message by Brian Ripley.
