loops

问题 I have a spatialtemporal dataset with various indicators for a set of location that I wish to map overtime. Here is my facet_wrap + loop #basemap basemap <- ggplot() + geom_sf(data= country_adm2) + coord_sf() + theme_void() print(basemap) #joining dataframe to polygons df_poly <- left_join(country_adm2, df, by= "County") ##joins the data by County. #loop & facet_wrap plots ## This goes over the dataset (df_poly) to plot the the three variables, and facet_wrap over ~Date to see time variation

问题 I am working on two tables as follows: A first table df1 giving a rate and a validity period: rates = {'rate': [ 0.974, 0.966, 0.996, 0.998, 0.994, 1.006, 1.042, 1.072, 0.954], 'Valid from': ['31/12/2018','15/01/2019','01/02/2019','01/03/2019','01/04/2019','15/04/2019','01/05/2019','01/06/2019','30/06/2019'], 'Valid to': ['14/01/2019','31/01/2019','28/02/2019','31/03/2019','14/04/2019','30/04/2019','31/05/2019','29/06/2019','31/07/2019']} df1 = pd.DataFrame(rates) df['Valid to'] = pd.to

问题 Problem: Refresh graphical representaion of Series in ChartObject after each iteration of for loop Ex. y=m*Cos(x) y - Values m - parameter I have some data counted from formula with parameter. I want to visualise what influence has the change of parameter on XYgraph. I want to do it in for loop (added Sleep do have some time to see results). Data and formula are in Excel SpreadSheet. Update script of parameter is in VBA module. Update works on values in spreadsheet but doesn't affect graph.

问题 for (Uri mUri : mSelected) { imagesRef = storageRef.child(postid + mUri.getLastPathSegment()); imagesRef.putFile(mUri).addOnSuccessListener(task4 -> db.collection("posts").document(postid).update("photo_id", FieldValue.arrayUnion(imagesRef.getDownloadUrl()))); } So, now i am working with firestore and firebase storage. I uploaded (multiple) images to the storage, and when it is uploaded, i get the download url and wants to add it into my firestore. So, the problem is, only the last image is

问题 My Code: while(scanf("%f", &number) && number > 0) while(scanf("%f", &number) == 1 && number > 0) What does this == 1 and is this necessary? 回答1: As, Weather Vane said in the comments, the ==1 is important if scanf() returns EOF (End Of File or -1) which would be evaluated to true and since the value in number remains unchanged from the previous iteration the condition of the while loop would be evaluated to true . This is not appropriate since we have an error at the scan process then and

问题 I have simple log file with timestamp in milliseconds like this one: [02/03/2020 07:53:58.859000] 5 [02/03/2020 07:53:58.935300] 2 [02/03/2020 10:04:50.355600] 0 [02/03/2020 10:04:51.028900] 1 [02/03/2020 10:38:13.468200] 6 And I want to achieve better readability so +-2seconds separate logs by dashes like this one: [02/03/2020 07:53:58.859000] 5 [02/03/2020 07:53:58.935300] 2 ------------------------------ [02/03/2020 10:04:50.355600] 0 [02/03/2020 10:04:51.028900] 1 ------------------------

问题 I was able to identify and extract all necessary e-mails I need. I also saved the attachments per e-mail to another variable. However, I'm having issue saving these attachments to a local folder, specifically those that are of file type = .xlsx. library(RDCOMClient) setwd("C:/Updated") outlook_app <- COMCreate("Outlook.Application") search <- outlook_app$AdvancedSearch( "Inbox", "urn:schemas:httpmail:subject like '%Daily Efficiency Tracker%'" ) Sys.sleep(10) results <- search$Results()

问题 Possible duplicate Hello, I'm struggling with output redirection within a bash for loop. I have several similar bash scripts, each scripts being launched on a different input file. The scripts called a tool with a few arguments. The bash scripts are like this : my_tool --input input_file --arg1 arg1_name --arg2 arg2_name > output_dir/result_X.dat X being a string which is unique for each script. I run all of them in a for loop : for script in scripts_dir/*.sh do bash $script done However, the
