问题 i am having some trouble masking a panel in the same way that I would a DataFrame. What I want to do feels simple, but I have not found a way looking at the docs and online forums. I have a simple example below: import pandas import numpy as np import datetime start_date = datetime.datetime(2009,3,1,6,29,59) r = pandas.date_range(start_date, periods=12) cols_1 = ['AAPL', 'AAPL', 'GOOG', 'GOOG', 'GS', 'GS'] cols_2 = ['close', 'rate', 'close', 'rate', 'close', 'rate'] dat = np.random.randn(12,

I am drawing box-percentile plots in R, using the box-percentile panel function from Hmisc ( panel.bpplot ) with bwplot from lattice . I have a numeric vector ( Length ), and would like to show its distribution across the levels of a factor variable ( Month ). Here's an example with fake data: For example, set.seed(13) Length<-sample(1:10, 1000, replace=TRUE) Month<-sample(c("Apr","May","Jul","Aug","Sep","Nov"), 1000, replace=TRUE) df<-cbind(Month, Length) df<-as.data.frame(df) df$Month<-factor(df$Month, levels=c("Apr","May","Jul","Aug","Sep","Nov")) df$Length<-as.numeric(df$Length) #plot

Does Android have the equivalent of a JPanel?

阅读更多关于 Does Android have the equivalent of a JPanel?

Is there an Android equivalent to Java's panel? I need something with a set size that I can add different views in dynamically. Is there such a technique? I'm basically wanting a blank area with a set size in xml code where I can add buttons later through the activity. The reason for adding later is the number of buttons and size of the buttons will range dramatically, but still needing the area to fill. There isn't a JPanel class in Android but you can use layouts just as effectively. Check out this link. 来源： https://stackoverflow.com/questions/11044984/does-android-have-the-equivalent-of-a

Primefaces 5 overlayPanel broken after update

阅读更多关于 Primefaces 5 overlayPanel broken after update

Today I discovered a new bug in P5. When I update the button which the overlay panel is referring to, it doesn't work anymore - The overlaypanel is not shown anymore. As a workaround I do use PF('widgetVar').loadContents(); but this feels very uncomfortable. In PF4 this did work without any workarounds. Anyone got some solution? I don't know exactly what you are pointing at. What do you mean with updating the button? For me the following code works fine with PrimeFaces 5.0: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java

Hausman's specification test for “glmer” from lme4

阅读更多关于 Hausman's specification test for “glmer” from lme4

I want to make a "Fixed/Random Models for Generalized linear model" (family="binomial"), because I have a data base where observations come from a population and there is a grouping structure. Then I use the function glmer from the lme4 package, also I have read that I can use the glmmPQL function from library MASS (Faraway,2006). My problem arises when I want to justify the use of random versus fixed model using the Hausman's test (Greene,2012), I don't find a specific function that allows me to do this similar to the phtest test featured in the package plm . How to justify using the random
