How to make a dataframe with lists or vectors as its elements












0












$begingroup$


This is something I have been wondering for ages but I am never able to get an answer.



I am trying to understand how to make a dataframe in R, where each element of the dataframe is itself a vector or a matrix.



For example, lets say we have a regular vector V with elements being real numbers.



Then to acess any number we would have



V[3] which would give the third element of said vector.



Now I want to know how to do this with say a dataframe D,



where each element of the dataframe is itself a vector or matrix, so that say



D[3] is not a real number, but a vector.



How can this be done in R?



Thanks all

          Dataframe is a representation of 2 D matrix in R. R does not support MultiIndex dataframes that can represent more complex structures.



          Maybe you can model the problem as a Tensor ( https://cran.r-project.org/web/packages/tensorr/vignettes/introduction.html , https://www.rdocumentation.org/packages/rTensor/versions/1.4/topics/Tensor-class)

                    How to label and detect the document text images

                    Image
                    1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...

Tabula Rosettana, [1] etiam titulo OGIS 90 agnita, est stela decreto de rebus sacris in Aegypto anno 196 a.C.n. lato inscripta. Tabula iuxta Rosettam Aegypti, urbem in delta Nili et ad oram maris Mediterranei iacentem, anno 1799 a milite Francico reperta est.
