Chart not rendering with Shiny R and NVD3

由 旧街凉风 提交于 2019-12-01 11:56:09
I have been attempting to create a Shiny timeseries plot using NVD3 library. Am relatively new to R, Shiny and NVD3. The problem is that when I run the ShinyApp, no chart renders on the browser. Using chromes developer tools, I can see that the div for myChart is created and populated with data, but not understanding why I cannot see the chart itself. Would appreciate any and all help on this matter... My code is like so: #ui.R require(rCharts) shinyUI(pageWithSidebar( headerPanel("Population Trend By Age Group:"), sidebarPanel( selectInput(inputId = "agegrp", label = "Choose Agegroup",

问题 I have a problem that seems to be quiet common but for which I haven't found a solution yet: When trying to publish a webapp using rCharts Parcoords, I get this error: ERROR: path[1]="": No such file or directory And the strange thing is that the app runs perfectly well on my laptop... Below is a simple version/example of the code that I'm using. Please note that you need to have downloaded the parcoords library and put it into the file where you're working before you run the code.

remove leaflet heatmap layer with rCharts and shiny

由 拟墨画扇 提交于 2019-12-01 08:39:17
I want to be able to let users see different heatmaps based on a parameter's choice in shiny, using rCharts and Leaflet. The first time the heatmap is displayed it looks great. All the other times the heat map is displayed as layers on top of the first one. How to reset the leaf map so that only the current layer / heat map is displayed? This sample code is based on the notorious Ramnath's Houston crime demo. library(shiny) library(rCharts) library(rjson) library(data.table) ## crimedt <- as.data.table(na.omit(ggmap::crime[,c("address","offense","lon","lat")])) crimedt <- crimedt[,offense:=as

rCharts - conflict between leaflet and nvd3 in Shiny

由 无人久伴 提交于 2019-12-01 05:26:22
问题 I am trying to include in the same shiny page both a leaflet map and a nvd3 rCharts graph. When I do so, leaflet is no longer displaying the circles / POI I used to display on the map (while not including nvd3). I suspect it is a JS / CSS conflict as when I try to include them separately it works just nice. Once I launch "runapp" and look at the html code, I can see the only difference when including both leaflet and nvd3 are the libraries in use: <link href="nvd3/css/nv.d3.css" rel=

Are rCharts and DT compatible in rmarkdown?

问题 I am trying to create a document with rmarkdown that includes both plots from the rCharts package and a datatable using the DT library included in htmlwidgets. For some reason I cannot display both of them together. --- title: "Untitled" output: html_document --- ```{r, echo=FALSE} library(DT) library(rCharts) df<-data.frame(Name=c("a","Z","h","k","j"),Value=(sample(10^7,5))) datatable(df, filter = 'top', options = list( pageLength = 10,iDisplaylength=10, autoWidth = TRUE )) ``` ```{r,

rCharts nvd3 library force ticks

由 爷，独闯天下 提交于 2019-11-30 22:18:33
I would like to force all tick marks and tick labels to appear along the axis in an rCharts nPlot from the nvd3 library. I have tried several approaches without success. This is the default behaviour: df <- data.frame(x = 1:13, y = rnorm(13)) library(rCharts) n <- nPlot(data = df, y ~ x, type = 'lineChart') n$yAxis(showMaxMin = FALSE) I would like to have all data in 1:13 show along the x axis. Ultimately, I have custom tickmarks I want to show equally-spaced with the following replacement: n$xAxis(tickFormat = "#! function (x) { ticklabels = ['0-1000', '1000-1500', '1500-1700', '1700-1820',
