if-statement

问题 Hi I am having trouble trying to get ifelse statements to work in a plotweb fuction (from bipartite ) to color interaction based on the total quantity of interaction of each cell in the matrix. I had the same problem with the high bar colors, but since there were only a few values and one vector, it was easy to manually code. Here is the code I am using, I want to color interactions greater than 15 as dark turquoise and keep the rest as default grey (grey80). I have tried many different

问题 I'm learning reactive programming with Reactor and I want to implement registration scenario where a user can have many accounts assigned to the same profile. However the username assigned to the profile and the phone assigned to the account must be unique. As you can see in the following snippet, this scenario will be easy to implement if Reactor was offering the operator switchIfNotEmpty . public Mono<PersonalAccountResponse> createPersonalAccount(PersonalAccountRequest request) { return

问题 I have two toggles (toggle-1 and toggle-2) with different contents in a header. I would like to prevent the user to have both toggles active simultaneously (otherwise they overlap). In the code below I tried to use if statements to hide one of the toggles if the other is already opened but it does not work. Ideally, what I would like to happen is that if toggle-1 is active and the user clicks on toggle-2, then toggle-1 would come back to its original state and toggle-2 would be now active.

问题 I have a dictionary with each keys having multiple values in a list. The tasks are: To detect whether a given word is in the dictionary values If it is true, then return the respective key from the dictionary Task 1 is achieved by using an if condition: if (word in dictionary[topics] for topics in dictionary.keys()) I want to get the topics when the if condition evaluates to be True. Something like if (word in dictionary[topics] for topics in dictionary.keys()): print topics 回答1: You can use

问题 I have a number of variables with the same name but different suffixes. For example, var1, var2, var3, var4, var5, var6, ... and so on. Each of these variables has a random sequence of 0, 1, and 2. Using these variables, I am trying to create a new variable called testvariable . If any of the already existing variables has 1, I will set testvariable to 1. If they have 0 or 2, I will assign 0. Is there a simple loop and/or ifelse statement I can use to create this variable? My real data is a

问题 I have below xslt where ID and LASTNAME are the input parameters. When ID matches the EMPLOYEE_ID in the VW_JAX_EMP_JOB_DEPTRECORDSELECT then set the Last_Name element as s0:PREFERREDLASTNAME otherwise se the input parameter LASTNAME. Below one doesnt work. <xsl:template name="GetLastNameVW_JAX_EMP_JOB_DEPT"> <xsl:param name="ID" /> <xsl:param name = "LASTNAME" /> <xsl:element name="Last_Name"> <xsl:choose> <xsl:when test="//s0:VW_JAX_EMP_JOB_DEPTRECORDSELECT[s0:EMPLOYEE_ID = $ID]/s0

问题 Say, I have a function in Python where if (age<20): young=True if (age>80): old=True My question is, if I want to call or print the values which are held as True. I want to write this line: The person wasn't selected for the job because he was old/young etc. One person could also violate many criteria. How would I do that? 回答1: To be sure: you want to print something if old or height is True . # This is needed if you want to check if old = false or true old = False height = False Your begin

问题 Just been playing with some basic functions and it seems rather strange how ifelse behaves if I use which() function as one of the arguments when the ifelse condition is true, e.g.: #I want to identify the location of all values above 6.5 #only if there are more than 90 values in the vector a: set.seed(100) a <- rnorm(100, mean=5, sd=1) ifelse(length(a)>90, which(a>6.5), NA) I get this output: [1] 4 When in fact it should be the following: [1] 4 15 25 40 44 47 65 How then can I make ifelse

问题 I have this Makefile $(MAIN) : $(OBJECTS) $(OBJECTS) : %.c compile file And i want to use printf for print something like "compiling" whenever a file needs compile and "done" if a file has been compiled at the end of every compiled for example: Compiling file1.c file2.c file3.c Done I have tried to use sentences like if from shell or ifeq from makefile but i need a variable and makefile doesn't let me change the value of a variable inside of a if i don't know why. How can i archive this? 回答1:

问题 I have a google sheet where people submit tasks they are working on and they'll submit a status update which is either 'in progress' or 'complete' for let's say task A. Task A is in column D[4] and Status is in column E[5]. I'm trying to get this code to only delete the 'in progress' row for Task A when there is duplicate Task A with the status being 'Complete'. This works for identifying the duplicate and removes the duplicate rows in order, but I'm not sure how to get it to only delete
