panel

问题 Please help me out. I have been stuck for a long time. I am an R beginner, and I want to know how to perform operations on data frame elements using multiple indices e.g. firms and time as in the below case elegantly? I want to perform some typical operations e.g year-wise mean on some other variables for each firm, and here is an example: I am want to calculate year-wise mean from daily data of variables A and F for all firms in the dataset. This is my dataset. I have used dplyr and hydroTSM

问题 I have an ASP panel with a modalpopupextender attached to it that is shown dynamically. Within the panel there are two labels that are dynamically populated with text when the panel popup is shown. however, when it is shown the labels are blank (missing). Below is my code for the HTML markup and code behind: HTML MARKUP <asp:Panel ID="pnlalert" runat="server" CssClass="modal"> <div class="rel"> <div class="modal-inner-wrapper-alert rounded-corners"> <div class="content rounded-corners"> <div

问题 I want to represent a tree factor dotplot with error bar combined with boxplot. I have complete almost all the graphic except that my error bar are overlapped. Concretely my idea is to jitter the dots and the error bars set.seed(1) data<-sample(rnorm(50,2,2),40) sd<-sample(rnorm(50,0.2,2),40) factor<-sample( LETTERS[1:3], 40, replace=TRUE, prob=c(0.3,.3, 0.3) ) frame<-data.frame(data,sd,factor) frame<-as.data.frame(frame) up=frame$data+frame$sd lo=frame$data-frame$sd bwplot(data ~ factor,

问题 I'd like to have a ListBox that sizes to its content, until some MaxRow property is met. So, if the MaxRow value was 3, it would behave in the following manner. Items.Count == 0 -> SizeToContent Items.Count == 1 -> SizeToContent Items.Count == 2 -> SizeToContent Items.Count == 3 -> SizeToContent Items.Count == 4 -> limit height to 3 rows and enable scrollbar Items.Count == 5 -> limit height to 3 rows and enable scrollbar etc etc I thought the correct way to do this would be to use a custom

问题 SOLUTION I was being an idiot and dynamically adding data-role="content" to the #wrapper element on page load, making it unrecognizable by JQM. I'm trying to implement a basic menu panel, but I'm having no luck getting it to animate or close. Below is the basic markup as generated by JQM. <div data-role="page" data-url="/" tabindex="0" class="ui-page ui-body-c ui-page-panel ui-page-active"> <div id="menu-panel" data-role="panel" data-position="left" data-display="reveal" data-dismissible=

问题 I want to write a questionnaire. It will be in a tab. I would like three columns: Question Number, Question, Group Box. I will have 14 of these so everything has to have their own row. The text in column 2 will sometimes be long enough to wrap. I feel like I have tried every combination, but I either get really big font or really small font. I'd like to be able to resize the window. Whatever I have done most recently makes it resize vertically, but no horizontally. I am very much a beginner

问题 Is there any way to put the JLabel in front of the rectangle? Currently, the JLabel is underneath the rectangle. Here is my relevant code: public class MainMenu_South extends JPanel { MainMenu_BlueJay t; JLabel start=new JLabel("START"); @Override public void paint(Graphics g) { super.paint(g); Graphics2D g2d = (Graphics2D) g; g2d.setColor(Color.blue); g2d.drawRect(0, 30, 900, 30); g2d.fillRect(0, 30, 900, 30); } public MainMenu_South(MainMenu_BlueJay t){ setLayout(null); this.t=t;

问题 I have a quick question. I am sure it is easy to do but I am missing something. How do I create a View Context of All Content/Node Types. Then I want to display my nodes in Panel 3 based on NID/Node ID? Is this the right way to go? Background: There are many teachers as Content Types. There is a page for all teachers eg www.example.com/all-teachers. If a user clicks on "a particular teacher" from this page they should be taken to: www.example.com/teacher-name - this page should display

问题 I am having trouble getting my graphs to appear in the 'plots' window of R studio - once I run the script they appear in a separate R graphics window, separate to R Studio, with the 'plots' tab blank. when i use dev.off() it gives the error *error in dev.off(): cannot shut down device 1 (the null device)* Even if i ran this command twice the error still there. I tried restart Rstudio- did not work 回答1: You might try suppressing the output of dev.off() Use- temp <- dev.off() Also refer similar
