  • Fractional y-var in ggplot

    - by Misha
    How can I easily create a fractional y-value when using ggplot? t <- as.factor(test=sample(seq(0,100,10),1000,rep=T)) d <- as.factor(sample(c(0,1),1000,rep=T) p <- data.frame(t,d) My best shot was: ggplot(p,aes(x=t,y=prop.table(table(t,d),1)[,1])) + geom_point() However this doesnt work and I guess there is an easier way around this...

  • Managing trace files on Sql Server 2005

    - by Sophtware
    I need to manage the trace files for a database on Sql Server 2005 Express Edition. The C2 audit logging is turned on for the database, and the files that it's creating are eating up a lot of space. Can this be done from within Sql Server, or do I need to write a service to monitor these files and take the appropriate actions? I found the [master].[sys].[trace] table with the trace file properties. Does anyone know the meaning of the fields in this table?

  • Excel: VLOOKUP that returns true or false?

    - by Svish
    In Excel we have the VLOOKUP function that looks for a value in a column in a table and then returns a value from a given column in that table if it finds something. If it doesn't, it produces an error. Is there a function that just returns true or false depending on if the value was found in a column or not?

  • What do you call the concept of dynamic data definition?

    - by DJTripleThreat
    Maybe this is simpler and more straightforward then what I'm thinking but I can't seem to find this concept on google anywhere. The concept is this: You have a table in a database and the table has a specified number of columns. However, it has been asked of me by previous clients that there also be a set of dynamic user defined columns that can be added on the fly. What is this concept called and is it considered a design pattern?

  • Extending DataGrid/Changing DataGrids header

    - by drasto
    Is there any way how to override DataGrids header line ? Or at least its behaviour ? I'm trying to implement Outlook-like grouping of the table. That is allow user to drag column header out of the table to the dedicated area to sort by that column (for example XamDataGrid has that feature, you can see how it works here). I cannot use any commercial solutions. I will be thankfull for any experiences, ideas, code, notes or tutorials.

  • How can I change column length using HQL query?

    - by gmugmu
    I tried session.createSQLQuery("ALTER TABLE People MODIFY address VARCHAR(1000);").executeUpdate(); but this throws org.hibernate.exception.SQLGrammarException: could not execute native bulk manipulation query After a lot of googling, the recommendation is to use HQL instead of SQL query to do bulk updates. Not sure how to use HQL to accomplish this. There seems to be no decent HQL documentation for updating column length in a table. Thanks so much for the help.
