rhandsontable

问题 I have the dataframe below: DF2 = data.frame(agency_postcode = factor(rep(c(12345,45678,24124,32525,32325),2)), car_group=factor(rep(c("Microcar","City car","Supermini","Compact","SUV"),2)), transmission=factor(rep(c("automatic","manual"),5))) and after subseting it by one of the values of the 1st column newdata <- DF2[ which(DF2$agency_postcode =='12345'), ] and re-factoring in order to set accordingly the dropdown values of the second and third column to only available values after the

问题 I am posting a link to the question - Rhandsontable in Shiny By removing xi as mentioned in the answers by @Ben https://stackoverflow.com/users/3460670/ben I was able to get the desired result. I have additional questions I want to change the column names into latex form. I am trying to use the latex2exp package, not sure where to include it When I hover over a data point, I want to get something like (a,b) instead of datavalues$data[,3]:a datavalues$data[,4]:b. You can see that in the 2nd

问题 I'd like to apply color highlighting for a entire row depending on a value and retain check boxes functionality of rhandsontable. In the simple example below, I'd like row 3 to be pink and row 4 to be green. library(rhandsontable) DF = data.frame( bool = TRUE,val = 1:10, big = LETTERS[1:10], small = letters[1:10], stringsAsFactors = FALSE) ###Checkboxes not Present/Entire row not highlighted rhandsontable(DF, readOnly = FALSE, width = 750, height = 300) %>% hot_cols(renderer = " function

问题 EDIT: I included observeEvent() in server.R as described in this video : https://www.youtube.com/watch?v=BzE1JmC0F6Q. It works partially. When I update A and B, the graph gets updated, but the columns C,D and E are giving wrong values and the number of rows keep growing. Any help is appreciated. I have 2 columns A and B. The user has the option to drag and drop values into A and B , and hence I am using rhandsontable (Source: https://jrowen.github.io/rhandsontable/) I have the code below for

问题 I am struggling to color full row of rhandsontable in my shiny app based on a cell value. In the following example, I would like to format full row instead of one cell. library(rhandsontable) DF = data.frame(val = 1:10, bool = TRUE, big = LETTERS[1:10], small = letters[1:10], dt = seq(from = Sys.Date(), by = "days", length.out = 10), stringsAsFactors = FALSE) col_highlight = 2 row_highlight = c(5, 7) rhandsontable(DF, width = 550, height = 300) %>% hot_cols(renderer = " function (instance, td

问题 I have an rhandsontable inside a shiny app. My goal is to color all cells in a column based on the sum of the column. Ex : if the sum of the values in the column is 1, then, all cells in this column are colored in green. The expected outcome displayed to the user is like this: It seems possible to do so with a JS formatting like this : rhandsontable(myrhandsontable) %>% hot_cols(renderer ="some JS script") I have never done any JS before and I struggle to get the sum of the column inside the
