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

Non repetitive permutations/combinations of elements
...number of columns. e.g. 1s and -1s for 3 columns can be done uniquely in 2^3 ways. -1 -1 -1 -1 -1 1 -1 1 -1 -1 1 1 1 -1 -1 1 -1 1 1 1 -1 1 1 1 and for 4 columns in 2^4 ways and so on. 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. How can I do this is R? I have looked at permn and combn in the combinat library and permutations and combinations in the gtools library and I am still confused as to how...

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/2018/04/03/finding-a-l...

2d color coded line plot
Hi! I'm not experienced very experienced with R and i'm looking for a way doing plots like in this example http://www.mathworks.de/matlabcentral/fx_files/23566/2/color_line3.png, which basically it is a 2d plot in which the 3rd dimension (variable) is color coded. I have only seen elsewhere that it is possible to color code dots in a scatter plot and I tried it with success although I I didn't find a way of including the color ba...

Problem in calling R functions from Matlab
...(on both 64 bit and 32 bit OS) . For this I have installed StatConnector (http://rcom.univie.ac.at/download/current/statconnDCOM.latest.exe) for calling R from within Matlab (R2009a) on Windows XP platform. I have added all the files of MATLAB_RLINK folder (downloaded from http://www.mathworks.com/matlabcentral/fileexchange/5051) into the default?Matlab working path?(D:\User\MATLAB) and also added the folder MATLAB_RLINK to the matlab path C:\Program Files\MATLAB\R2009a\toolbox . It seems that Matlab is able to connect to R however I am facing a problem while trying to call R functions from within Matla...

File Exchange?
Hi, I've been using R for a number of years, and must say I really like it. This past summer, however, I started using MatLab for a course at school and found the file exchange it has ( http://www.mathworks.com/matlabcentral/fileexchange/loadCategory.do) to be extremely useful. I know that R has packages that people share, and that there's also RForge for more advanced tools... But is there anywhere where people share R scripts? For example, if I make a function that does one specific task, but I don't want...

R function for Woody Average (Average with alignment)?
Dear R users, I'm looking for a function to align multiple waveforms that contain random phase shifts. The "Woody Average" is one such method -- is there any comparable function already coded for R? Matlab code for this type of average exists [http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=12459&objectType=FILE] but I don't speak matlab. Cheers, Uri
