I'm super new to all of this so please excuse any mistakes in my terminology. I'm trying to install the MRInstruments package in R using the following-
install_github("MRCIEU/MRInstruments")
But i am getting this message-
Skipping install of 'MRInstruments' from a github remote, the SHA1 (efa2ca0d) has not changed since last install.
Use force = TRUE to force installation
I've tried doing as it says and using force = TRUE to force the installation but it just creates a value in the environment and still doesn't install.
Can anyone shed any light on what I am doing wrong please?
I tried installing from Github using devtools(),
devtools::install_github("MRCIEU/MRInstruments")
And got no errors. Try uninstalling the package, and re-install it and see what happens.
remove.packages("MRInstruments");
devtools::install_github("MRCIEU/MRInstruments")
I know this topic is not new but still I havent found a solution.
The TAB autocomplete/ intellisense for Jupyter notebooks doesnt seem to work properly.
I have tried the following possible fixes from several sources:
downgrade jedi=0.17.2
downgrade parso=0.6.2
install pyreadline
nothing really worked reliably. The only thing which seems to fix this is to add the following line on top of each notebook.
%config Completer.use_jedi = False
But thats not a proper solution. So I figured maybe uninstall jedi altogether.
So my question is: is JEDI really needed to run Juypter Notebooks properly?
Many thanks in advance

I use Anaconda to start Jupyter notebook.
However, since this week, I get the error that Jupyter cannot find Mathplotlib, but it is look in the wrong directory, I think.
I think it should look in a directory under'Anaconda3'? The problems started when I installed Python again, I think. It's as if there are two versions installled and Jupiter Notebook cannot find my libraries anymore.
Reinstalling Anaconda navigator may fix the issue!
I installed Scilab 5.5.2 on Windows 10, and then installed the Scilab Code Generator toolbox.
However, when I start Scilab, the following message appears and I can't use the toolbox. This problem occurs for every toolbox.
Start Scilab Code Generator
Version: 0.9.20190122
Load macros
atomsLoad: An error occurred while loading 'xcos_code_generator-0.9.20190122':
File "C:\Users\光\AppData\Roaming\Scilab\SCILAB~1.2\atoms\x64\XCOS_C~1\09E129~1.201\macros\names" does not exist or read access denied.
(光 is my username.)
I suppose the problem comes from "\Scilab\SCILAB~1.2" in the middle of the file path. In my computer, the only folder in "Scilab" is "scilab-5.5.2", so indeed the software cannot find the file it's looking for.
Does anyone have any ideas?
I need to use the toolbox at work soon, so any help is greatly appreciated. Thank you in advance.
Note: I'm not using the latest Scilab 6.0.2 because it fails to work on my computer. It closes immediately after I open it.
I solved the problem by myself.
It was my user name "光" that caused the problem. I found people saying that user names in full-width characters such as Japanese sometimes cause problems like this.
The solution is to create another user account with a name in half-width characters and install Scilab in that account. (Just changing the full-width user name doesn't work because it doesn't change the filenames that already exist.)
I couldn't find the solution until today because I was searching for solutions only in the context of Scilab, not in the context of software in general.
I hope this answer helps someone.
I'm not sure why you are using an outdated version of Scilab. The latest version is 6.0.2 on Windows. If the newer version doesn't work properly then that's the problem you need to fix first. To test your Scilab installation you may run it in the terminal. Find the installation folder. For me, it is C:\Program Files\scilab-6.0.2\bin the on cmd go to the path and run Scilex.exe. If not uninstall everything and install it in a proper way. My recommendation is to uninstall the old Scilab you already have. Then:
Install Chocolatey package manager
Open PowerShell as Admin and run choco update all -y, once in a while update your packages this way.
run choco install Scilab -y
then open the Scilab software
run the atomsInstall("xcos_code_generator") in the console
runt the atomsLoad("xcos_code_generator") to make sure your package is installed properly. You should see this as a result:
--> atomsInstall("xcos_code_generator")
Scanning repository http://atoms.scilab.org/6.0 ... Done
ans =

When I start RStudio, none of the windows inside the main frame come up, and none of the menu options display menu options when clicked. It's just an blank page.
It feels like some kind of graphics rendering or window management problem.
I'm running Windows 7. I have the latest version of R, which is 3.1.1. I have the latest RStudio, which is 98.1062.
How to fix it?
Reset the RStudio state. Do this:
Close RStudio if open.
Go to this directory: %localappdata%\RStudio-Desktop
Rename that directory as a type of backup.
Start RStudio.
RStudio will see the configuration directory is missing and regenerate it with correct values.
Everything should work after that.
Other threads I found helpful here are:

https://support.rstudio.com/hc/communities/public/questions/200666647-RStudio-096-16-Windows-7-gives-empty-screen?locale=en-us
Thanks!
Renaming the RStudio state by renaming %localappdata%\RStudio-Desktop did not work for me. However i made it work by renaming another config folder in %appdata% instead.
Close RStudio
Go to this directory: %appdata%\RStudio
Rename the folder
Restart RStudio
I faced the same issue when I downgraded my version of R.
I did try the above solutions. However, it didn't work for me.
After some googling, I found out that the issue was because now I had a different version of R installed. Here's how you can choose the version of R and rectify the issue.
Navigate to the RStudio installation folder. (C:\Program Files\RStudio\bin)
Press and hold Control Key
Double click on rstudio.exe
Choose a specific version of R (whichever you want to work with)
Click OK and RStudio should open without any issues.
NB: I use 64bit Windows 8.1.
I had the same issue and I almost gave up about solving it but then I found a suggestion that GitHub might be the problem. I am not sure how that is happening but the minute I uninstalled GitHub and re-launched Rstudio, it worked perfectly as nothing happened!? Here is the link for where I found the suggestion on Rstudio community page: (https://support.rstudio.com/hc/communities/public/questions/200983187-R-studio-0-98-797-for-mac-opens-as-blank-white-page)
I had the same problem and figured out that for some reason R was blocked on the step of loading my library from a website (I added it to Rprofile for auto-load). You can test the following:
1) Try to run just R console, not RStudio, and then click on blank space - normally some information should appear
2) Try to launch without network connection
On a Mac (Running Yosemite 10.10.3) this is what worked for me:
Move/Rename ~/.rstudio-desktop
(Many responses have mentioned this, but this by itself didn't help.)
Then I shutdown my Mac and restarted it. RStudio worked when I logged back in.
Before that, I tried every one of the steps mentioned here and in many other links, including re-downloading R and RStudio, but unfortunately none of those steps helped in my case.
Search this documentation for 'Blank GUI'.
This is what I found which worked for me:
In Windows Explorer, go to C:\Users\currentUser\AppData\Roaming\RStudio.
Delete the Desktop.ini file
This technique forces RStudio to refresh and default to open-source R as the engine
Same issue I faced so I unistalled the windows installer and downloaded zip version from this link https://www.rstudio.com/products/rstudio/download/
Unziped It and pasted it into c drive and created shortcut from Rstudio/bin/rstudio.exe file.
Working properly after that no issue. In windows installer checked that r session is not working due to an missing dll.
So try to install from ZIP
I had the same problem like Thomas
When I start RStudio, none on the windows inside the main frame come up, and none of the menu options display menu options when clicked. It's just an blank page.
My problem was, that i uninstalled R because is thought RStudio will work on its own.
So i uninstalled RStudio and deleting every existing file which was created by R or RStudio.
In the next step i installed RStudio again.
It was asking for a Version of R (which i dont had in this state). So i installed R again and everything is working fine now. I hope this helps
I had a slight variation of the problem that might be of interest. I had set up an aliases.cmd to run my cygwin bash shell automatically upon launch of a cmd terminal as per:
https://superuser.com/questions/302194/automatically-executing-commands-when-a-command-prompt-is-opened
What RStudio was doing was launching a few cmd windows in the background to (I assume) populate each pane and the console.
This was triggering a bash shell which wasn't returning and was hanging RStudio.
If you have this issue you can just manually kill the sub bash terminals spawned by cmd via ProcessExplorer/TaskManager and RStudio will continue to launch normally.
If anyone else has set anything to launch automatically on init of a cmd terminal then this could interfere in the same way with RStudio.
The RStudio devs could probably fix this behind the scenes by changing the way they spawn cmd terminals in the gui.
I had a similar problem. After trying the options above with no luck, I uninstalled Rx64 3.5.0 and installed an older version, R x64 3.2.2.
Rstudio then worked perfect.
