traminer

I am querying the github public dataset on BigQuery. Currently, my best query for what I need looks like the following. SELECT type, created_at, repository_name FROM [githubarchive:github.timeline] WHERE (created_at CONTAINS '2012-') AND repository_owner="twitter" ORDER BY created_at, repository_name; This gives me all the events ("type") from the repository_owner twitter (or any other user) for all the repositories ("repository_name") that this user owns, but in a single column. However, what I really want is to have all the events ("type") in columns, one column for each repository (

I want to select columns from a data frame so that the resulting continuous column-sequences are as long as possible, while the number of rows with NAs is as small as possible, because they have to be dropped afterwards. (The reason I want to do this is, that I want to run TraMineR::seqsubm() to automatically get a matrix of transition costs (by transition probability) and later run cluster::agnes() on it. TraMineR::seqsubm() doesn't like NA states and cluster::agnes() with NA states in the matrix doesn't necessarily make much sense.) For that purpose I already wrote a working function that

enter image description hereA common problem 1 2 in the publication of a sequence analysis or generally of graphs with many categorical states is that they are not easily transferable to b/w paper publications. There are some tools, like Colorbrewer , which can help to make a well informed decision on grey scale colors. Nonetheless, the results are unsatisfactory if the color palette exceeds 5 or more shades of greys. Thus, it would be really helpful to add pattern fills to certain graph areas in these cases (although this is not recommended by the famous Edward Tufte). Would it be possible to

Suppose there are three sequences to be compared: a, b, and c. Traditionally, the resulting 3-by-3 pairwise distance matrix is symmetric , indicating that the distance from a to b is equal to the distance from b to a. I am wondering if TraMineR provides some way to produce an asymmetric pairwise distance matrix. No, TraMineR does not produce 'assymetric' dissimilaries precisely for the reasons stressed in Pat's comment. The main interest of computing pairwise dissimilarities between sequences is that once we have such dissimilarities we can for instance measure the discrepancy among sequences,

I am trying to create a sequence object with seqdef using SPELL format. Here is an example of my data: spell <- structure(list(ID = c(1, 3, 3, 4, 5, 5, 6, 8, 9, 10, 11, 11, 12, 13, 13, 13, 13, 14, 14, 14, 14, 14, 14, 14, 14, 14, 15, 15, 15, 15, 15, 15, 15, 16, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19), status = c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 2, 3, 1, 2, 3, 2, 3, 1, 1, 1, 3, 1, 3, 3, 1, 3, 1, 1, 1, 1, 1, 3, 3, 1, 3, 1, 1, 1), time1 = c(1, 1,
