问题 I have a string like this: 100 Stupid Street ; Government Tower 7; Chicago Palm, MA 92111 I want to return all the characters to the left of the last semicolon. To the left of the last semicolon would be: 100 Stupid Street ; Government Tower 7 That was step 1. I would also like to extract characters from this string: Chicago Palm, MA 92111 I want to return all the characters to the right and left of the second to last space. So, To the right of the second to last space would be: MA 92111 To

问题 My SUMIFS needs to add up column D (D11:D172) and the first criteria is a range called qbplistcomp (which is column B so B11:B172) for multiple hits (e.g. CHF, COPD, and all STROKE so using STROKE*) and the second criteria is in column C (C11:C172) looking for the criteria which is a label "qbp volumes" ... so far without subtotaling, this formula works as: =SUM(SUMIFS(D11:D172,qbplistcomp,{"CHF","COPD","STROKE*"},C11:C172,"QBP Volumes")) Now my column A has the ability to filter on Category,

问题 I have the following example data set in excel. Currently, for reference, John,Smith is in A4 and Smith Johnson is in B4. Column 1 = Names of Members Column 2 = Attended (list of members that attended a meeting). Applied to column 1, I would like to add a function that turns GREEN any members that are in column 2 (attended) that are also in column 1. Like so: The solution used in the end was to use this formula, which does the trick: =SUMPRODUCT(--(MID($A4&" "&$A4,FIND(",",$A4)+2,FIND(",",$A4

问题 A newbie here, can someone help me to figure it out. I have the follwoing data in Excel: Column A: T1 T2 T3 2T1 3T2 1T3 I want to return how often T1 occurs in column A.. T1 in column A should be 3 (T1 + 2T1) Does someone know how to solve this problem? 回答1: Possibly multiple ways, one way would be: Formula in C2 : =SUM(IF(MID(A$1:A$6,SEARCH("T",A$1:A$6),LEN(A$1:A$6))=B2,IFERROR(LEFT(A$1:A$6,SEARCH("T",A$1:A$6)-1)*1,1),0)) Note: Confirm through Ctrl Shift Enter 来源： https://stackoverflow.com

问题 I have a column in Excel that looks like the below: And what I want is a formula that can copy the column into the next column splitting each cell with multiple values so that each cell will only contain a single value. Similar to this: Thanks for your help! 回答1: Use Powerquery, Split by linefeed and into new rows =) Let's imagine this set of data: Select your data, A1:A7 in this example. Import this data into PowerQuery AKA Get&Transform (including headers). Under "Home" click, "Split Column

问题 I came pretty close to solving my problem with this answer given by "barry houdini" But I run into problems incorporating it to my needs. =SUMPRODUCT(VALUE(0&SUBSTITUTE(A1:A8,"*",""))) Edit #3 - @Rory came with a very good answer to solving my problem. But what I hadn't thought about was if you enter a non-numerical value inside a cell, then the formula returns an error. So I would really like to tweak the following formula to ignore the letter "x" , or non-numerical values (if that's easier)

问题 I use an excel file in which I determine the names of sensor, and a formula allowing me to create a new "synthetic" sensor based on real sensors. I would like to write the formula as string like for example "y1 + y2 + y3" and not "df ['y1'] + df ['y2'] + df ['y3]" but I don't see which method to use? Excel file example: My script must therefore create a new sensor for each line of this excel file. This new sensor will then be uploaded to my database. The number of sensors to calculate the new

问题 I'm building a model in R, while excluding 'office' column in the formula (it sometimes contains hints of the class I predict ). I'm learning on 'train' and predicting on 'test': > model <- randomForest::randomForest(tc ~ . - office, data=train, importance=TRUE,proximity=TRUE ) > prediction <- predict(model, test, type = "class") the prediction resulted with all NAs: > head(prediction) [1] <NA> <NA> <NA> <NA> <NA> <NA> Levels: 2668 2752 2921 3005 the reason is that test$office contains NAs: >
