问题 i hope this one isn´t stupid. I have two dataframes with Variables ID and gender/sex. In df1, there are NAs. In df2, the variable is complete. I want to complete the column in df1 with the values from df2. (In df1 the variable is called "gender". In df2 it is called "sex".) Here is what i tried so far: #example-data ID<-seq(1,30,by=1) df1<-as.data.frame(ID) df2<-df1 df1$gender<-c(NA,"2","1",NA,"2","2","2","2","2","2",NA,"2","1","1",NA,"2","2","2","2","2","1","2","2",NA,"2","2","2","2","2",NA)

问题 I would like find the fastes way in R to indentify indexes of elements in Ytimes array which are closest to given Xtimes values. So far I have been using a simple for-loop, but there must be a better way to do it: Xtimes <- c(1,5,8,10,15,19,23,34,45,51,55,57,78,120) Ytimes <- seq(0,120,length.out = 1000) YmatchIndex = array(0,length(Xtimes)) for (i in 1:length(Xtimes)) { YmatchIndex[i] = which.min(abs(Ytimes - Xtimes[i])) } print(Ytimes[YmatchIndex]) 回答1: R is vectorized, so skip the for loop

问题 why does my sintax is not right? SELECT *, MATCH(tags,title,description) AGAINST ('asd jhbdckdsb' IN BOOLEAN MODE) AS score FROM blogs WHERE score > 0 ORDER BY score DESC, insert_datetime DESC, id DESC ; the problem seems to be on WHERE condition :/ 回答1: invisible columns and column alias are not allowed in WHERE so use HAVING HAVING score > 0 instead of WHERE 回答2: You cannot use a column alias in the WHERE clause. You must repeat the MATCH a second time. 来源： https://stackoverflow.com

问题 I have a bunch of rows and 25 columns in a worksheet, and need to find the value in the 4th column based on columns B and C using VBA. I am using a combination of index and multiple condition match functions. I tried to follow along via https://www.mrexcel.com/forum/showthread.php?650832-VBA-Multiple-Criteria-Index-Match and pass an integer variable into vba array formula to no avail. I made this macro which works: Sub VariablesInArrayFormula() SA = "Apples" C1 = "Oranges" Range("D27").Select

问题 I'm trying to match the highlighted parts of this string: <iframe maybe something here src="http://some.random.url.com/" and the string continues... I need to match the src="" if it's placed inside of an tag. The iframe tag can be placed anywhere in the source. Thanks in advance! :) 回答1: You should use a DOM parser for that.
