This is my first time using R and I was wondering what to do. I thought I installed these two packages but I got this message after I tried to run the library.
What I see when I try to run the code:

I'm writing an R package using devtools and roxygen2. Note that this is my first time making a package, so maybe I am missing something important.
I want to add a dependency, the package, DESeq2. I have tried to do this in a number of ways, but believe the right way is to add the following to my DESCRIPTIONS file.
Depends:
DESeq2
If I add this, when I build and reload I get a fatal error. When running in RStudio it just gives a "Fatal Error" dialog and restarts the application. It appears to build, but when it does, library(myPackage), it crashes immediately.
If I remove the Depends section from the DESCRIPTIONS file it builds and loads fine. What's more, if I include a different package, for example, ggplot2, then it builds and loads fine as well.
What about a package would cause it to fail to load as a dependency and completely crash? Is there another way to require it or is there any way to dig deeper into the cause?
Thanks very much in advance.
I have plotted the graph using a code in R using library function which is part of certain package.
I want to use this code in powerbi to plot the graph. But I am not able to add the package (library function) in power bi?
For a Power BI Desktop scenario, it calls the R Installation specified in the Power BI Options. So you need to add the packages you want via that R Installation.
For an app.powerbi.com scenario, you are limited to the list of packages they support, ref:
https://powerbi.microsoft.com/en-us/documentation/powerbi-service-r-visuals/
Just to clarify, are you trying to install packages or add packages that you already have into R?
Unfortunately Power BI isn't an IDE for the R language, so you will need to install the packages that you want via your R IDE or command prompt.
If you are trying to use packages that are already installed on your machine, for example, the package plotrix, then you can use the R script editor in the Visualisations tab like this:
require(plotrix)
or
library(plotrix)
Please post an update to show if this has helped you. :)
Was just now gone through the same problem: everything was loading fine except the visual created with R which required me to use ggplot2 and it was giving an error saying
there is no package called ggplot2
In order to solve it, opened RStudio and in the console ran
install.packages("ggplot2")
Then, went back to PowerBI and clicked "Atualizar" (which means "Update" in portuguese)
and the visual showed up without any errors.

I have configured RStudio to run R code natively on Greenplum. I have searched online but I couldn't find answer to the problem I am facing at the moment.
I have imported the library(PivotalR) and library(RPostgreSQL). But, when I type madlib it just comes up with few of the functions:
The Greenplum database has also been configured with Madlib functions including madlib.forest_train, which does not show up in RStudio. I am assuming it has something to do with the PivotalR package for RStudio. Is there a way to make the forest_train work directly from RStudio?
Can anybody give me some direction on editing source code of an R package? From what I've seen, changing the package from within R does not seem to be possible. In editing outside of R, I'm stuck at unpacking the tar.gz. While I can now modify the function to my heart's content, the folder looks nothing like the working snow library. I presume I will need to turn the contents into a tar.gz once again and install it in the standard way?
My colleagues and I have been attempting to get makeSOCKcluster() to work with remote IPs for the past three days. Hangs indefinitely. After digging into the snow package I've found the issue to be in the way newSOCKnode() calls socketConnection(). If I run makeSOCKcluster("IP", manual=T) and then put the output into powershell, it results in the connection being made but the program not completing. However, I can run makeSOCKcluster("IP", manual=T) in one R instance and then run system("output", wait=F, input="") in another instance which results in the program completing. I believe I can simply modify snow to do this automatically.
