new 1.3.7 and fix for CVE-2018-10392 (issue 2335)?
...mp(), but also for releasing an official 1.3.7 release with these fixes and other bug fixes! We really appreciate your work on clarifying the CVE fix. Plus with the new release I can upgrade from 1.3.6 to 1.3.7 instead of having to patch piecemeal from the master branch. Please let us know how MathWorks can help with the libvorbis project moving forward. We’re happy to work with you!

inverse F distribution in R?
Dear all, I'm looking for a function that calls the inverse F-distribution. Something equivalent to FINV in matlab or excel. Does anyone know if such a function already exists for R? (I haven't been able to find one.) Thanks for any leads. Best, Jennifer

New matrix function
Hi All, I was looking for a function to find a small matrix inside a larger matrix in R similar to the one described in the following link: https://www.mathworks.com/matlabcentral/answers/194708-index-a-small-matrix-in-a-larger-matrix I couldn't find anything. The above function can be seen as a "generalisation" of the "which" function as well as the function described in the following post: https://coolbutuseless.github.io/2018/...

return first index for each unique value in a vector
...he unique values (2,5,9) but also their first indices (2,4,1). I tried using a for loop with which(A==unique(A)[i])[1] to find the first index of each unique value but it is very slow. What I am trying to do is easily and quickly done with the "unique" function in MATLAB (see http://www.mathworks.com/help/techdoc/ref/unique.html).

How can I slightly offset plots?
Dear R help contributers, I have several x,y scatter plots and I would like to plot them slightly offset, similar to: http://www.mathworks.com/matlabcentral/fx_files/24368/2/content/style4.jpg I've looked all over for this answer with no luck. Just a function name or previous example would probably be enough for me to figure it out. Thank-you in advance, Carly

I finally used the function combn([0 1],3) that I found at the following link http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=7147&objectType=FILE written by Jos van der Geest in Matlab which generated the above.

Fit a 3-Dimensional Line to Data Points
...perts, I am new to R, and was wondering how to do 3D linear regression in R. In other words, I need to Fit a 3-Dimensional Line to Data Points (input). I googled before posting this, and found that it is possible in Matlab and other commercial packages. For example, see the Matlab link: http://www.mathworks.com/products/statistics/demos.html?file=/products/demos/shipping/stats/orthoregdemo.html#10 Is there a way to achieve this in R? Thanks!
