Hello! Is it posible to apply /cumsum()/ along the 3rd dimension of 3D array? Something like matrlab function - /cumsum (*A*,dim)/ which returns the cumulative sum of the elements along the dimension of *A* specified by scalar dim. Thanks in advance ?eljka -- View this message in context: http://r.789695.n4.nabble.com/cumsum-in-3d-arrays-tp4110470p4110470.html Sent from the R help mailing

Hi, I want to convert my MATLAB programs to R studio programs. Kindly guide on the same. [[alternative HTML version deleted]]

Hi, Using Google with a search phrase such as "MATLAB to R" will yield a number of possible resources for you such as: http://www.math.umaine.edu/~hiebeler/comp/matlabR.pdf which provides a reference for associating MATLAB code to R equivalents. You can then take it from there. Also, a clarification on your misunderstanding above, which seems to be prevalent from what I can tell on various online fora. R Studio is a third party GUI that sits on...

I'm a new R user and am looking for an R equivalent to the Matlab 'cp2tform' function (see: http://www.mathworks.com/help/toolbox/images/ref/cp2tform.html). cp2tform accepts pairs of 2D control points and produces a least-squares optimized spatial transformation from one set of points to the other. Specifically, I'm looking to produce the coefficients of a 3rd order polynomial

Hi, I am trying to convert some Matlab code into R for running some experiments and I was wondering if there is some function in R which does the work of the gradient function in Matlab calculating the "gradient" of 1-, 2- and 3-d images. I only need the 3-d calculations for running these experiments. Many thanks and best wishes, Ranjan

I made some matlab codes... Is there any method to perform matlab codes in R program?? -- View this message in context: http://r.789695.n4.nabble.com/hi-guestion-tp2311219p2311219.html Sent from the R help mailing list archive at Nabble.com.

Hi there I am new user of r, i would need some help to translate som code for vectors in matlab to r. I have managed to translate the first 7 rows, but not the rest. Could anyone give me any suggestions for this problem?? Matlab code: tempo=[]; temps=[]; tempn=[]; tempao=[]; tempas=[]; tempan=[]; for k=1:5 tempo = [tempo n_o(k,:)]; temps = [temps n_s(k,:)]; tempn = [tempn

HI, I'm looking for a function that does the same as deal() in MATLAB, i,e, for an array x[1 2 3] [a,b,c]=x; such that a=1, b=2, c=3 Does R have any functions similar to this? [[alternative HTML version deleted]]

Hi, I have what I think is a simple question/issue but I have unable to find the answer for it either in the R-manual or by browsing the web. I would like to know if there is a "mode" function in R, such that from a vector or matrix the function returns the most common value. In other programs I use (such as Matlab) I can have for exampe a 3X3 matrix A, A=[1 2 3; 1 3 2; 3 3 2] and I

Hello all, I am new to R but have some experience with MATLAB and am trying to make the switch. I generally find the two languages easy to adapt but there are a few routine tasks which I would like to run smoother in R and I am having trouble finding a help resource. Could someone suggest a guide to filtering, selecting, sorting, and processing biological matrix data? Here is a rudimentary

Dear All, Currently, I am translating Matlab code to R. I met difficulties to translate such Matlab codes into R: fprintf(fid,(' SPLITTING RESULTS ')); fprintf(fid,(' \n')); fprintf(fid,' Data base to analyze is a matrix %4i x %2i ',[n m]); fprintf(fid,' \n'); fprintf(fid,' h is %2i',h); fprintf(fid,' \n'); fprintf(fid,' group=0

The rules for conformability of objects required for various operators remain a mystery as do some related problems like the rules for recycling in creating arrays etc. Would someone be able to direct me to where such rules are stated? In a related vein, there are all manner of operations that are readily coded in Gauss or in MATA that fail, often mysteriously, in R. Are there some

So, trying to convert a very long, somewhat technical bit of lin alg MATLAB code to R. Most of it working, but raninto a stumbling block that is probaably simple enough for someone to explain. Basically, trying to 'line up' MATLAB results from an element-wise division of a matrix by a vector with R output. Here is a simplified version of the MATLAB code I'm translating: NN = [1,
