pivot

问题 Is there a quick way to "unpivot" an Excel matrix/pivot-table (in Excel or elsewhere), without writing macros or other code ? Again, I can write code (C# or VBA or whatever) that does that myselfs. I want to know if it is possible to do it without code, quickly ? E.g. I need to convert this permission matrix (given as Excel-table/matrix) into this half-normalized table (so I can insert it into a SQL database): e.g. in SQL I could do it like this: CREATE TABLE dbo.T_DocumentMatrix ( [Function]

问题 Im sure this is a simple technique although I can't find an answer so far! I have TIMESTAMP | POINTNAME | VALUE 2012-10-10 16:00:00 AHU01 20 2012-10-10 16:00:00 AHU02 25 2012-10-10 16:00:15 AHU01 26 2012-10-10 16:00:15 AHU02 35 etc... ( for approx 800 POINTNAMES) with many pointnames I dont want to list each one in the 'IN' clause of the pivot 'FOR' (as syntax given below) definition but would like to use perhaps a subquery. So what I would like is all the POINTNAME values as columns with A

问题 I have a dataframe: ID questions value A 1 8 A 1.1 7 A 1.2 -3 B 1 7 B 4.3 7 ... ... ... I'm trying to pivot the data on "questions" such that the data frame will look like this: ID 1 1.1 1.2 4.3 A 8 7 -3 NA B ... ... ... 7 ... Using the pivot_wider() function, I ran into an error: df %>% pivot_wider(names_from = question, values_from = value) Values in `rating` are not uniquely identified; output will contain list-cols. * Use `values_fn = list(rating = list)` to suppress this warning. * Use

问题 I am guessing this is a noob question so please bear with me.
