paste

问题 Anyone know the keyboard shortcut to copy/paste a line into a new line in Eclipse , without having to highlight the entire line? ctrl - alt - down turns my whole screen upside down (I'm on windows). Interestingly, that's what's specified in the windows->preferences. 回答1: Ctrl - Alt - Down : copies current line or selected lines to below Ctrl - Alt - Up :: copies current line or selected lines to above Ctrl - Shift - L : brings up a List of shortcut keys See Windows/Preference->General->Keys.

问题 Say there's a vector x: x <- c("a", " ", "b") and I want to quickly turn this into a single string "a b". Is there a way to do this without a loop? I know with a loop I could do this: y <- "" for (i in 1:3){ paste(y, x[i], sep = "") } > y [1] "a b" but I will need to do this over many, many iterations, and having to loop over this and replace the original with the new each time would become very time consuming. I always want to be able to do something like this: x <- paste(x) as if paste()

问题 I would like to take a data frame with characters and numbers, and concatenate all of the elements of the each row into a single string, which would be stored as a single element in a vector. As an example, I make a data frame of letters and numbers, and then I would like to concatenate the first row via the paste function, and hopefully return the value "A1" df <- data.frame(letters = LETTERS[1:5], numbers = 1:5) df ## letters numbers ## 1 A 1 ## 2 B 2 ## 3 C 3 ## 4 D 4 ## 5 E 5 paste(df[1,]

问题 I'm looking for a way to sanitize input that I paste into the browser, is this possible to do with jQuery? I've managed to come up with this so far: $(this).live(pasteEventName, function(e) { // this is where i would like to sanitize my input return false; } Unfortunately my development has come to a screeching hold because of this "minor" issue. I would really make me a happy camper if someone could point me to the right direction. 回答1: OK, just bumped into the same issue.. I went around the

问题 I am using a Windows machine connected to CentOS 7 through MobaXterm . I want the middle mouse button to work in Vim 7.4 (compiled without the clipboard option) as it does on the linux command line, which is to paste from my Windows clipboard. In my ~/.vimrc : nnoremap <MiddleMouse> :set paste<cr>:startinsert<MiddleMouse><esc> At first, I worried that this might not do what I expect because maybe I don't understand how Vim does recursion, so I tried it with Shift + Insert , since that is what

问题 I made custom contextual action bar in Webview. And there are copy and paste buttons. Copy action is working with ClipboardManager. But pasting method doesn't work. I referenced this link and problem with setting enabled. MenuItem mPasteItem = menu.findItem(R.id.menu_paste); if (!(clipboard.hasPrimaryClip())) { mPasteItem.setEnabled(false); } else if (!(clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN))) { mPasteItem.setEnabled(false); } else { mPasteItem.setEnabled(true)

问题 I am using the paste command as below: message+=$(paste <(echo "${arr[0]}") <(echo "$starttimeF") <(echo "$ttime") <(echo "$time") | column -t) echo "$message" It gives me the following output: ASPPPLD121 11:45:00 00:00:16 00:02:23 FPASDDF123 11:45:00 00:00:16 00:02:23 ZWASD77F0D 09:04:58 02:40:18 03:51:10 DDPADSDSD5 11:29:41 00:15:35 01:17:33 How do I redirect this to a CSV or an EXCEL FILE? OR How do I put it into HTML table? 回答1: You have three questions in one. The easiest to solve is the

问题 I am trying to run a "for" loop in R to analyze multiple variables. I have a data set ("DataSet") with column names ("AppleTag1", "AppleTag2", "CherryTag1", "CherryTag2"....). The loop is to compare "Tag1" with "Tag2" columns for each unique column name listed in "ColumnName" and obtain a vector with unique values from both columns. My question is how do I refer to the result of a paste function as a variable. I know the first past function used to collect the unique results can be fixed with

问题 I am trying to write an excel macro that will copy all my worksheets into one single worksheet. All worksheets are layed out the same, 4 columns with data in every cell of every row. Each sheet has a header. I am trying to copy the prefiltered data from each sheet to a results sheet, the data from each sheet will be stacked on top of each other. So far this is what I have and it's almost working. Dim sh As Worksheet Dim iRows As Long iRows = 0 For Each sh In ActiveWorkbook.Worksheets sh
