Feb 20	comment	How to achieve Set+Part like behaviour in custom Set function? @Mr.Wizard Yes, I made sure both symbol have `HoldFirst`. Looking at `Trace` it looks like it gets evaluated just before being passed to `DFSetInner`, but, fair warning´, I'm not very good at interpreting the output of `Trace`.
Feb 20	comment	How to achieve Set+Part like behaviour in custom Set function? The first version with `Block` doesn't work. `Part` is still getting evaluated. The later two do work, though. :)
Feb 20	comment	How to achieve Set+Part like behaviour in custom Set function? Yes, that is correct. The code isn't there for wading through, but so that one can have a complete test case to copy/paste.
Feb 14	comment	Get DownValues that do not involve patterns? Nice! This also seems to be the faster solution when the number and size of the `DownValues` get big.
Feb 10	comment	Different highlight for each cluster in DendrogramPlot I was hoping for that each cluster, according to the `HighlightLevel` would have each own color. In the example the cluster of 1, 4, 2, 3 would have one color and the cluster of 7, 5, 6, 8 would have another color and so on.
Feb 6	comment	Creating a R DataFrame like construct in Mathematica One problem: If there are only three or fewer variabled in the dataframe then the `DataFrame["Names"]` and `Format[DataFrame` don't work.
Feb 6	comment	Creating a R DataFrame like construct in Mathematica Wow what a great answer. I didn't know about `TagSet`. It opens up all kinds of interesting ways of extending dataframes. :)
Feb 2	comment	Exporting Mathematica expression as SVG My hope is to be able to distribute the svg files to other people.
Jan 27	comment	Summing along rows or columns of a matrix I think you may have confused rows and columns. By default `Total` sum along the columns.
Nov 9	comment	Getting slightly different results in fitting a logit model in R and Mathematica Thank you. It was one of those mistakes that seems obvious in hindsight.
Oct 8	comment	Customizing FrameTicks in DistributionChart Thank you. Your workaround works perfectly. `DistributionChart` seems quite buggy. This is not the first bug in it I've run in to.
Oct 3	comment	Getting the 557th element of a table `Select` is for picking out all elements in a list that match some criteria. Using it to simply get the 557th elements is making things complicated.
Oct 3	comment	Getting the 557th element of a table Sounds more like `Part` is what he is looking for.
Aug 12	comment	Importing tabular data that has been exported from Evernote That works! It ends up wrapping it in a bunch of {}, but that is just and excuse for `First@First@First@First`. Thank you. I must have spent hours trying to get this to work, and what I could come up with was much more brittle and complex and still kept messing up the data. I must admit the second argument for `Import` remains a mystery for me.
Aug 12	comment	Importing tabular data that has been exported from Evernote The cell is empty, which means Evernote puts a simple <br /> tag in the cell.
Aug 12	comment	Importing tabular data that has been exported from Evernote It works almost perfectly. The one edge case it stumbles upon is the one I didn't think to include in the text example: missing data. If there is a value missing in a row it just leaves it out making that particular sub-list shorter, which mean the columns end up misaligned.
Jul 4	comment	How do you round numbers so that it affects computation? Ah! Now I feel stupid. I did look at that but for some reason I assumed a had to be a whole number.
Jun 6	comment	Standard errors for maximum likelihood estimates in FindDistributionParameters @SjoerdC.deVries Isn't this a good use-case for `ParallelTable`?
May 22	comment	LogLikelihood function from the Time Series package is apparently missing @Szabolcs Thank you. I found it in the `$BaseDirectory`. After browsing through the code I also managed to figure out what the problem is. Apparently they've renamed the function, they just haven't bothered to update the documentation.
May 22	comment	LogLikelihood function from the Time Series package is apparently missing @SjoerdC.deVries I've exactly tried several of the examples from the documents, including the one on page 80. None work.
