Paste all combinations of a vector in R

由 北城余情 提交于 2019-11-28 02:01:58
I have a vector say: vec = c("A", "B", "C") And I want to paste single combinations of every item in the vector to get the result AB AC BC I know I can use outer to get all possible combinations of the vector, but I am stumped as how to only get the result above. Order doesn't matter in this case, so the result could plausibly also be BA CA CB I just need to combine the single pairs. Sam Try combn combn(vec,2, FUN=paste, collapse='') #[1] "AB" "AC" "BC" 来源： https://stackoverflow.com/questions/29549562/paste-all-combinations-of-a-vector-in-r

Paste two text lists (one list a file) into one list separated by semicolon

由 北战南征 提交于 2019-11-28 00:56:19
问题 An example of the process/output would be: File1: hello world File2: foo bar Resulting file after concatenation: File3: hello;foo world;bar For a large list of non-predictive text (no-wild cards - but lines are aligned as above). I cannot figure out how to do this with the paste command under Ubuntu. 回答1: paste -d';' File1 File2 > File3 回答2: cat concatenates by lines (or, more accurately, doesn't care what the contents are). What you seem to need is something more like paste . $ paste -d\;

Use “pastefromword” Filtering on All Pasted Content in CKEditor 3

由 自作多情 提交于 2019-11-28 00:45:06
问题 CKEditor is a great editor and the pastefromword plugin is very good. I'd like to have the filtering provided by the plugin applied to all pasted text. For example, when pasting from word, all fonts and sizes are stripped. This does not happen when pasting from an email. That said, I came up with the following solution and posting it here to get some feedback. I'm wondering if I made it too complicated, or if there is an easier way. I kind of just copied the code from pastefromword/plugin.js.

Paste/Collapse in R

由 主宰稳场 提交于 2019-11-27 22:14:28
I'm confused by paste, and thought it was just simple concatenating. whales <- c("C","D","C","D","D") quails <- c("D","D","D","D","D") results <-paste(whales, quails, collapse = '') Why would this return "C DD DC DD DD D" instead of CD DD CD DD DD? Moreover, why would results <-paste(whales[1], quails[1], collapse = '') return "C D" ? with a space? Thanks, D EDIT OK, I see that results <-paste(whales, quails, collapse = NULL, sep='') will get me what I want, but an explanation of why the previous code didn't work? And also thank you to the answerers. For the first question, try the following

Assigning and removing objects in a loop: eval(parse(paste(

由 我与影子孤独终老i 提交于 2019-11-27 21:58:15
问题 I am looking to assign objects in a loop. I've read that some form of eval(parse( is what I need to perform this, but I'm running into errors listing invalid text or no such file or directory. Below is sample code of generally what I'm attempting to do: x <- array(seq(1,18,by=1),dim=c(3,2,3)) for (i in 1:length(x[1,1,])) { eval(parse(paste(letters[i],"<-mean(x[,,",i,"])",sep="") } And when I'm finished using these objects, I would like to remove them (the actual objects are very large and

How to disable Pasting in a TextField in Swift?

由 柔情痞子 提交于 2019-11-27 20:01:10
I've got a TextField with a number pad and the function runs only if it contains numbers. The only option that the user will crash the app is if he will paste letters in the TextField and click OK. How can I disable pasting in the TextField? TimeString I agree with Leonardo Savio Dabus, if I were you I'll use string checking and just give out a warning, it makes things easier. BUT, if disabling paste option is a fancy feature you really want to put into your app, then you need to do more work. I'll provide the steps below. Step 1: You need to create another class which extends the UITextField

javascript cut/copy/paste to clipboard: how did Google solve it?

由 给你一囗甜甜゛ 提交于 2019-11-27 17:38:01
Yes, this question has been asked again and again: how to copy and paste from and to the system clipboard with javascript? I have found only partial solutions and hacks so far. The reason that it has been asked so often in the past is that there still is no working solution. However, I saw that Google Docs actually has a working solution now for both keyboard events as well as buttons. So, it is possible, but how do they do it? Software Salad article, Accessing the System Clipboard with JavaScript – A Holy Grail? , gives a nice overview of the problem (but it's a few years old). In short: you

How do you copy/paste from the clipboard in C++?

由 孤者浪人 提交于 2019-11-27 14:05:49
I'm still a C++ newbie who has only recently learned some file manipulation. I looked it up online and the codes given are way beyond my current skill. Is there a simple way to do this, or are there any good tutorials that can explain this from the very basics? In windows look at the following API: OpenClipBoard EmptyClipboard SetClipboardData CloseClipboard GetClipboardData An extensive discussion can be found here . Obviously this topic is strongly operating system related. And if you are using some framework (ie MFC/ATL) you generally find some helper infrastructure. This reply refer to the
