Change cell background of rHandsontable with afterChange event on client side

由 让人想犯罪 __ 提交于 2020-12-30 01:38:58
问题 I'd like to change the background color of a handsontable cell after it's been edited by the user on the client side. The handsontable is defined through a Shiny application; so this is really a question about how to define event hooks in rHandsontable in the Shiny application. The general use case that I'm trying to accomplish is: users edit cell data; the background color change to indicate that it's been changed and is pending saving to a database; the change is passed back to Shiny's

在数据科学方面，python和R有何区别?

　　python和R都是当下比较流行的编程语言，拥有强大的生态系统和社区，受到大家的追捧和喜欢，那么在数据科学方面，python和R有何区别?我们来看看吧。 　　大多数深度学习研究都使用python完成的，因此Keras和PyTorch之类的工具具有python优先的开发，你可以在Keras的深度学习简介中了解这些主题。 　　python和R之上具有优势的另一个领域就是将模型部署到其他软件中，python是一种通用的编程语言，因此，如果您在使用python编写应用程序，包含基于python的模型的过程是无缝的。我们在python设计机器学习工作流中介绍了部署模型和构建python的数据工程管道。 　　python通常被认为是一种通用语言，具有易于理解的语法。 　　在R中进行大流的统计建模研究，有多种模型可供选择。R的另一个大窍门是使用Shiny轻松创建仪表板，对于没有太多技术经验的人来说，可以创建发布仪表板并进行分享。 　　R的功能在开发时考虑了统计学家的问题，从而赋予特定领域的优势，比如说数据可视化功能。 　　python最初是用于软件开发的编程语言，对于具有计算机科学或者软件开发的人员来说可以更容易使用，而且从其他语言过度到python要比R更加简单。 来源： oschina 链接： https://my.oschina.net/u/4408222/blog/4839636

Shinyjs is not working properly due to shiny reactivity

问题 I have the shiny app below in which the user uploads a file (here I just put the dt in a reactive function) and from there he can choose which columns he wants to display as selectInput() via a pickerInput() . Then he should be able to click on Update2 and see the map. The user should also be able to update the depth and stations values by multiplying all of them with the numericInput() value1 and value2 respectively and create a new sliderInput() and therefore update the dataframe that is

问题 I'm trying to make a shiny module that will alter a datatable based on a custom searchbar. I managed to make an app that will print the results of a searchbar search into R-Studio console, but, how do I return the results from the module and update the reactive data storage? Here is an example app, I want to return what is printed to update the reactive: myModuleUI <- function(id) { ns <- NS(id) tagList( fluidRow( column(width=2, textInput(ns("searchField"), "Search"), dataTableOutput("table"
