caret

I am building a KNN model to predict housing prices. I'll go through my data and my model and then my problem. Data - # A tibble: 81,334 x 4 latitude longitude close_date close_price <dbl> <dbl> <dttm> <dbl> 1 36.4 -98.7 2014-08-05 06:34:00 147504. 2 36.6 -97.9 2014-08-12 23:48:00 137401. 3 36.6 -97.9 2014-08-09 04:00:40 239105. Model - library(caret) training.samples <- data$close_price %>% createDataPartition(p = 0.8, list = FALSE) train.data <- data[training.samples, ] test.data <- data[-training.samples, ] model <- train( close_price~ ., data = train.data, method = "knn", trControl =

I am struggling to move the caret in a textbox editing control within a DataGridView , one line up and one line down, just as a user would get when pressing up and down arrows. So I don't mean lines as what is between newline characters, I mean lines as what is between the left and right side of a textbox. I cannot use GetCharIndexFromPosition and GetPositionFromCharIndex because not all text will always be shown in the textbox display area. Edit: I cannot simulate KeyPress because I am dealing with a textbox cell within a DataGridView. My aim is in fact getting arrow keys to do what they

I'm making a WYSIWYG editor, and I need to know how to get caret position working. It appears that there's no obvious way of doing it cross-platform. I just need the syntax. Please don't point me towards the Mozilla developer page; I didn't find it particularly useful. I'm using a content editable div. source that i looked at try this function doGetCaretPosition (oField) { // Initialize var iCaretPos = 0; // IE Support if (document.selection) { // Set focus on the element oField.focus (); // To get cursor position, get empty selection range var oSel = document.selection.createRange (); // Move

I have a simple textarea and I need to make transparent letters while allowing the text-caret to be visible. When I apply the following rules then I get invisible caret: textarea { background: transparent; opacity: 0; } When I type invisible text, I need to see the text-caret move. EDIT: I need to make editor to edit td cell in table. When I click on a cell I show a textarea and start typing. On a each character letter, I insert a context in a cell. After that, I hide a textarea. arttronics This jsFiddle DEMO uses an online tutorial method that has been slightly modified to create a non-native

I want to change color of caret and make it not relative from input text, because it's hard to make it look good when it is. There are two ways I have done this. If you want this to affect all carets on your site (probably not preferred) then you could override the caret css class in you: .caret{border-top:4px solid red;} Another option is to create a custom class and add it to the caret in your markup .red{border-top:4px solid red;} <div class="btn-group"> <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">Action<span class="caret red"></span></button> <ul

I have a contentEditable div. Let's say the user clicks a button that inserts HTML into the editable area. So, they click a button and the following is added to the innerHTML of the contentEditable div: <div id="outside"><div id="inside"></div></div> How do I automatically place the cursor (ie caret) IN the "inside" div? Worse. How can this work in IE and FF? For IE: var range= document.body.createTextRange(); range.moveToElementText(document.getElementById('inside')); range.select(); For Mozilla: var range= document.createRange(); range.selectNodeContents(document.getElementById('inside'));
