Test Match and Order between two vectors in R

由 拟墨画扇 提交于 2019-12-24 08:49:04
问题 I would like to test the match and order between two vectors. I'm aware of the match function; are there overlays to assess the order simultaneously? For example: x <- c("a", "b", "c") y <- c("b", "a", "c") x %in% y There are perfect matches, but the ordering is not correct. Thoughts on how to identify that? Thanks. 回答1: test_match_order <- function(x,y) { if (all(x==y)) print('Perfect match in same order') if (!all(x==y) && all(sort(x)==sort(y))) print('Perfect match in wrong order') if (

Getting last match from multiple matches

问题 I am trying to match and get the last occurrence of a pattern in my file using notepad++. My text: X12 Source =asdjkasjd file="x/y1.dun" "x/y2.dun" "x/y3.dun" asds12 X22 p/q/xy.dun asda=23 source =asdf X44 1000 1001 file="abc.dun" What I expect using find-and-replace is this: X12 x/y3.dun X22 p/q/xy.dun X44 abc.dun What I have tried so far: (X\d{2}).*?([^"\s]+dun)((?!X\d{2}).)* replace with: $1\t\t$2\n But it returns me this: X12 x/y1.dun //Which is the first match X22 p/q/xy.dun X44 abc.dun

Regex: String match including punctuation

问题 From another question, I have this expression to match words in a sentence: var sentence = "Exclamation! Question? Full stop. Ellipsis..."; console.log(sentence.toLowerCase().match(/\w+(?:'\w+)*/g)); It works perfectly. However, now I am looking for a way to match exclamation marks, question marks, and full stops separately. The result should look like this: [ "exclamation", "!", "question", "?", "full", "stop", ".", "ellipsis", "." ] Only matching one dot from the ellipsis, not all three

Index match x 2?

问题 I am using the following index match formula: =IFERROR(INDEX(Data!V:V,MATCH(Home!F16,Data!C:C,0)),INDEX(Contacts!E:E,Home!H16 & "*",Contacts!B:B,0)) I am trying to lookup a vlaue on sheet Data, and if the value is not found then look up the value on sheet contacts. This always seems to be returning 0. Please can someone show me where i am going wrong? 回答1: You are missing the MATCH on the second INDEX: =IFERROR(INDEX(Data!V:V,MATCH(Home!F16,Data!C:C,0)),INDEX(Contacts!E:E,MATCH(Home!H16 & "*"

conditional data.table match for subset of data.table

问题 This post is related to the previous post here: match rows of two data.tables to fill subset of a data.table Not sure how I can integrate them together. I have a situation where other than the NA for one column of DT1, a couple of more conditions should apply for merging, but that doesn't work. > DT1 <- data.table(colA = c(1,1, 2,2,2,3,3), colB = c('A', NA, 'AA', 'B', NA, 'A', 'C'), timeA = c(2,4,3,4,6,1,4)) > DT1 colA colB timeA 1: 1 A 2 2: 1 <NA> 4 3: 2 AA 3 4: 2 B 4 5: 2 <NA> 6 6: 3 A 1 7:

Ignore date in a string with numbers using regular expression

由 十年热恋 提交于 2019-12-24 03:51:28
问题 I have a little Problem. i use [0-9\,.]* to finde a decimal in a string. And ([^\s]+) to find the text behind the first number. The string looks normally like this. 1 number a text and than a date: 1.023,45 stück 24.05.10 but sometimes I had just the date and then i become 240510 as decimal. And sometimes I had just the decimal. How should I modify the regex to find the date if existing and remove it? And then look for a decimal an select this if existing. Thanks in advance. 回答1: Divide and
