| Hello all, I have been working on technical analysis algorithms since the year 2000. As an Electrical Engineer with a Ph.D., with a specialization in signal processing and Pattern Recognition as well as 18 years of teaching Computer Science at a... |
| Hello Eric, Based on your suggestion that the x means that the interpreter seems to see a multiplication, I went ahead and tried different scenarios and indeed whenever an implicit multiplication was a possibility, the x would appear. That solves... |
| As I played more with my problem, I decided to convert my Dataset to its Normal form as a local Association variable in the function using Module so: f[dataset_Dataset] := Module[{localVar = dataset // Normal}, .......]; In this way, I now deal... |
| Thank you Rohit. I will go back and reread that part of the documentation. |
| Rohit, I now have a further question. Join[d1,d2] works great. But how would I Join N files whose names are in a list. For example, assume I have filenames = {fn1,fn2,fn3,fn4,..fnN} I could use a loop that reads each csv file as a Dataset and... |
| I am providing the file. The problem is that others seem to be able to read that file using SemanticImport[]. When I edit the sample file so that it has 200 rows rather than the 257, I am able to read it directly with SemanticImport[] but beyond... |
| After thinking a bit about it I think that I might actually have an answer to my own question. I think I have been thinking the wrong way about Mathematica's capabilities with respect to events. As usual, Mathematica surprises me with its approach to... |
| I will do that though I have read a lot about patterns. In any case, something that would be great would be a repository of patterns. Some already exist in the documentation, but we would need more. I know that with regular expressions there are... |
| In the past when I would type 1+1 and hit SHIFT ENTER I would get out[some number]= 2 Now I get out[some number] 2 Note the extra empty line after the out[number] Did I inadvertently change... |
| Thank you again Rohit, That was what I thought I might have to do. I will use that approach. |
