facet

问题 I'm fairly new to Lucene's Term Vectors - and want to make sure my term gathering is as efficient as it possibly can be. I'm getting the unique terms and then retrieving the docFreq() of the term to perform faceting. I'm gathering all documents terms from the index using: lindex = SimpleFSDirectory(File(indexdir)) ireader = IndexReader.open(lindex, True) terms = ireader.terms() #Returns TermEnum This works fine, but is there a way to only return terms for specific fields (across all documents

问题 Does anybody know a good link with a list of all existign JSF/Tobago facets containing explanation what the facet is good for? Until now I know about the "layout" and "confirmation" facet but I haven't found a website showing up all the other existing facets... Thanks in advance! 回答1: Usually the documentation for the individual tags has a description for their facets. For example, http://java.sun.com/javaee/javaserverfaces/1.2/docs/tlddocs/h/dataTable.html describes some of the facts it

问题 I have been having trouble with the tag <f:facet> . I am working form other examples of code which use it, but I'm not sure exactly what purpose it serves. I have written some code which in method is exactly the same as other code I have seen which works, except there's is wrapped in a <f:facet name=actions> tag. When I add this around my code the drop down box I am wrapping it around disappears when I deploy. Anyone able to suggest a reason for this or give me an insight into how and when to

问题 I have the a problem in ploting the data with ggplot. I couldn't make the data inside each facet to be ordered correctly. my sample data is: data <- structure(list(Parameter = c("{0.1, 0.7, 0.0, 0.2}", "{0.2, 0.7, 0.0, 0.1}", "{0.3, 0.7, 0.0, 0.0}", "{0.0, 0.7, 0.0, 0.3}", "{0.0, 0.6, 0.0, 0.4}", "{0.1, 0.6, 0.0, 0.3}", "{0.2, 0.6, 0.0, 0.2}", "{0.3, 0.6, 0.0, 0.1}", "{0.4, 0.6, 0.0, 0.0}", "{0.1, 0.3, 0.2, 0.4}", "{0.1, 0.7, 0.0, 0.2}", "{0.2, 0.7, 0.0, 0.1}", "{0.3, 0.7, 0.0, 0.0}", "{0.0,

问题 I've a data.frame that looks like this: > foo class type (0,10] (10,20] (20,30] (30,40] 1 A <NA> 0.6 0.2 0.1 0.1 2 B <NA> 0.7 0.1 0.1 0.1 3 C 1 0.5 0.4 0.1 0.0 4 C 2 0.5 0.3 0.1 0.1 5 D 1 0.7 0.3 0.0 0.0 6 D 2 0.7 0.2 0.0 0.1 7 E 1 0.4 0.3 0.2 0.1 8 E 2 0.5 0.3 0.1 0.1 I melt by class & type and do a barplot: ggplot(melt(foo, id=c("class", "type")), aes(x=variable, y=value, fill=class)) + geom_bar(position="dodge") + facet_grid(type ~.) In fact, facet_grid() creates 3 graphs, but what I want

问题 I have created a plot like the one here with ggplot2 package and facet_wrap function, and I would like to suppress some of the x-axis text to make it more legible. For example, here it would be more legible if the x-axis scales appeared only on boxes D, F, H and J. How could I do that? Thanks in advance! EDIT : the reproducible code library(ggplot2) d <- ggplot(diamonds, aes(carat, price, fill = ..density..)) + xlim(0, 2) + stat_binhex(na.rm = TRUE) + theme(aspect.ratio = 1) d + facet_wrap(~

问题 I feel like I keep going in circles with this one. I followed the Getting Started guide for Google App Engine (https://developers.google.com/appengine/docs/java/gettingstarted/) in Eclipse and everything went relatively well until I uploaded it to the App Engine. I was getting 500 errors so I checked the logs and found this: "guestbook/SignGuestbookServlet : Unsupported major.minor version 51.0]" I then search for this problem (on stackoverflow, of course) and found this solution: Google App
