sliding

问题 I'm trying to figure out how to a query to generate an ARRAY given a sliding window over a character column with Postgre. For example, if I have this: pid <chr> 1 WP_096038768.1 2 WP_013465871.1 3 WP_058155244.1 4 WP_011329269.1 5 WP_058374608.1 6 WP_089368983.1 7 WP_096739105.1 8 WP_089346667.1 9 WP_096041177.1 10 WP_010553306.1 ... I want a sliding window of size 1 before and after the row. The result is this: pid g <chr> <chr> 1 WP_013465871.1 WP_096038768.1,WP_013465871.1,WP_058155244.1 2

问题 Data flag 2017-01-01 17.2 False 2017-01-02 17.0 False 2017-01-03 16.8 False 2017-01-04 18.3 False 2017-01-05 19.1 True ... 2017-12-28 20.1 False 2017-12-29 19.8 False 2017-12-30 18.9 False 2017-12-31 19.5 False There is a pandas dataframe that has values and flag. I want to calculate mean values by rolling(window=30), if the flag is "NOT TRUE". 回答1: You can use pandas.rolling_mean() while subsetting the dataframe to only include entries where df.flag is false (the ~ operator inverts the truth

问题 I saw a couple libraries that can do this, but i would like to avoid them if possible. I managed to do left to right, but i couldn't find out how to do on both directions. so here is my code: final SlidingPaneLayout slidingPaneLayout = SlidingPaneLayout.class.cast(root.findViewById(R.id.slidingpanelayout)); slidingPaneLayout.setPanelSlideListener(new SlidingPaneLayout.PanelSlideListener() { @Override public void onPanelSlide(View view, float v) { } @Override public void onPanelOpened(View

问题 I am trying to solve this problem: where U is here: s=c*e(t)+e_dot(t) and e(t)=theta(t)-thetad(t) and e_dot(t)=theta_dot(t)-thetad_dot(t) where thetad(theta desired)=sin(t)-- i.e signal to be tracked! and thetad_dot=cos(t),J=10,c=0.5,eta=0.5 I tried first with odeint- it gave error after t=0.4 that is theta(solution of above differential equation) fell flat to 0 and stayed thereafter. However when I tried to increase mxstep to 5000000 I could get somewhat correct graph till t=4.3s. I want to

问题 I am quite new to python and programming in general, but I am trying to run a "sliding window" calculation over a tab delimited .txt file that contains about 7 million lines with python. What I mean by sliding window is that it will run a calculation over say 50,000 lines, report the number and then move up say 10,000 lines and perform the same calculation over another 50,000 lines. I have the calculation and the "sliding window" working correctly and it runs well if I test it on a a small

问题 If I have three activities, I want to move from one activity to another when touching the moving on the screen horizontally(from left to right or right to left). how to access the action of sliding the screen and ? 回答1: try this: try { Intent newIntent = new Intent(view.getContext(), NewActivity.class); startActivityForResult(newIntent, 0); overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.slide_out_right); } catch(Exception ex) { } 回答2: http://android-developers.blogspot

问题 I am using a sliding menu from here in my application. My app also has a GraphView in which I set some data in real time. The graph is a linear graph which is scrollable, to the left and to the right. But, having the sliding menu by a left to right gesture, the user cannot scroll in the graph because the menu keeps popping out. Is there any way I can overwrite the menu functionality when a certain item is pressed? The graph item is just a LinearLayout. I am also using fragments, so each menu

问题 I'm adding pages run time when swipeleft is happened. But when swiperight happened I can't return the previous page that I'm created with sliding from left to right . I have added the data-direction="reverse" to the pages but it didn't create left-to-right effect. Is there any way to do this? 回答1: A maybe easier way using JQM would be: <a href="page.html" data-transition="slide" data-direction="reverse">Link Text</a> or also, within js as: $.mobile.changePage("page.html", { transition: 'slide

问题 I have some picture, let's say like rectangular piece of paper. I want to position it on the center of the screen, and when user slides left or right with its finger (let's say left), that piece of paper should go left (with the finger), and from the right should come new piece of paper with some new information. I hope that my description isn't confusing. I guess that this functionality should be easy to do with iOS SDK, I just don't know what to use ... Thanks for any help ;) 回答1: You'll

问题 I'm making a view and an activity extending SherlockMapActivity and using SlidingMenu libraries to make my main view to scroll like Google+ does. I've added the SlidingMenu by XML and my view scrolls perfectly showing the hidden menu but it only scrolls the view below the action bar. In Google+ app it also scrolls the action bar and I've seen there's a function for making my action bar sliding enabled but it does not work. What would be the best way to make my action bar sliding with the full
