When I tried your code, it also stated that the function was deprecated and to use data_to_hierarchical. Although, it's never quite that simple, right? I tried multiple ways to get hctreemap2 to work, but wasn't able to discern that issue. From there I turned to the package recommended data_to_hierarchical. Now that worked without an issue--once I figured out the right type, which in hindsight seemed kind-of obvious.

That being said, this is what I've got:

QUESTION

Only show these panels if the plot type is a barplot. R shiny

Asked 2021-Dec-16 at 20:01

I want the user to select the type of plot to display.

In case the type of plot is 'barplot' new selection variables should appear. In this case "binning" and "breaks".

However, the code below is not working properly. No new variables are display after conditionalPanel.

Here you have the RepEx.

ANSWER

Answered 2021-Dec-16 at 20:01

You have to add "input.graph == 'Barplot'" to the conditions. These conditions are not R code but JS passed as a string and then converted by the function itself.

Datatable output for Apriori results not displaying in R Shiny App

Asked 2021-Aug-05 at 01:37

I'm developing a Shiny app which takes specific city/state inputs and processes these inputs through the Apriori function (arules package). I am running into an issue where I can not get the results to output as a datatable. I have tried various combinations; both utilizing the DT and shiny packages. My current code is below. I know the Apriori function is working because I receive an output in the console when I run the application. (1st screenshot show the app and the error I am receiving, 2nd screenshot show the output from the console, 3rd screenshot shows that by using renderPrint I receive a text output (not listed below in Server or UI code).

Thanks in advance! I appreciate any and all feedback!

I was able to figure out the issue by changing the server side script to read (for whatever reason the DT is visible when I run the App in Rstudio but not visible once published in shiny server):

Association rules having same support but different confidence values

Asked 2020-Dec-01 at 00:42

I am generating rules from my data and one thing I noticed were a few duplicated rules. These rules have the same support, lift and count values but different confidence and coverage values.

I initially thought this was due to a white space in one of the product names but I have trimmed and cleaned the product info before mining for rules.

R Arules Item Frequency Plot Rotate Axis labels

Asked 2020-Jun-01 at 23:30

I'm doing some pattern mining in R using library(arules). Using ItemFrequencyPlot I am trying to rotate the x-axis labels and scale the axis names.

...

ANSWER

Answered 2020-Jun-01 at 23:30

itemFrequencyPlot does not appear to allow you to control those labels, but it is after all just a barplot, which does give you more control of the appearance. So just make your own. Here is how. Get the top 20 frequencies. Leave lots of room for the long axis labels. And plot!

shiny docker image build failed due to ubuntu package issue

I'm trying to build docker image for my R shiny app. Below is theDockerfile.

ANSWER

Answered 2020-May-18 at 08:14

The error message you are receiving is not Docker specific, but rather concerns your package manager apt.

Although you are updating the package list using apt-get update, you do not install newer versions of packages. What happens now is that you are trying to install a newer version of an already installed package which leads to the error message.

If you use apt-get upgrade, apt will install the newer versions of your installed packages.

Changing the 5th line as shown below will fix that issue:

RUN apt-get update && apt-get upgrade -y && apt-get install -y \

When I build my images, everything else seems fine, except I got error message Error in library(devtools) : there is no package called ‘devtools’ Execution halted. I also tried devtools::install_github('nik01010/dashboardthemes') with no success. I have non clue why? What could go wrong? Do anyone know what is wrong with my dockerfile? Thanks a lot.

ANSWER

Answered 2020-May-13 at 05:11

There are a few approaches you might try.

Easiest:

Use remotes::install_github instead of devtools. remotes has many fewer dependencies if you don't need the other functionality.

Second Easiest:

Use rocker/tidyverse image from Docker Hub instead of baseR image.
