 Nov2 comment How to deal with too much recursion This works nicely, thanks! Feb20 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. Feb20 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. :) Feb20 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. Feb14 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. Feb10 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. Feb6 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. Feb6 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. :) Feb2 comment Exporting Mathematica expression as SVG My hope is to be able to distribute the svg files to other people. Jan27 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. Nov9 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. Oct8 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. Oct3 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. Oct3 comment Getting the 557th element of a table Sounds more like Part is what he is looking for. Aug12 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. Aug12 comment Importing tabular data that has been exported from Evernote The cell is empty, which means Evernote puts a simple
tag in the cell. Aug12 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. Jul4 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. Jun6 comment Standard errors for maximum likelihood estimates in FindDistributionParameters @SjoerdC.deVries Isn't this a good use-case for ParallelTable? May22 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.
