gertstulp / ggplotgui Goto Github PK

I am using R for several years with statistics and plot, but not worked with GitHub yet.

This project is so great because I also want to combine shiny with ggplot2 before years ago, but I dont know where to start.

So I am really happy when I saw this project, and I want to work together to make this better.

Are you still maintaining this, and what can I do ?

Thank you

Changing delimiter for uploaded CSV files has no effect. This is due to a bug in the code: the block

 if (input$file_type == "text") {
          data <- read_delim(file_in$datapath,
                             delim = input$text_delim,
                             col_names = TRUE)

upload_delim must be used instead of text_delim

There is a problem on ggplotgui startup, an error with DataTable does not load data.

"DataTables warning: DataTables_Table_0 - requested unknown parameter '4' for row 0.

I LOVE this web app and have started using it to help teach ggplot to four labs of 11-13 students each.

I'm running into a pair of issues that is making this more difficult (though not impossible).

First issue:
When students run the web app, it crashes due to the traffic of 8-13 students using it at the same time.

Second issue:
When we install and run the app directly via RStudio, we get the following error...
DataTables warning: table id=DataTables_Table_0 - Requested unknown parameter '4' for row 0. For more information about this error, please see http://datatables.net/tn/4
...the same issue appears for both standalone app and rstudio.cloud, and same issue also appears for installation of either CRAN version or devtools version.

So my question is whether it might be possible either to:
(1) Up the capacity of the web app to be able to handle more parallel traffic, or
(2) Squash the bug in the directly loadable version (or share any quick thoughts or advice that might help me to fix it myself, which I'll be working on in any case)

Many thanks for creating this wonderful resource!

p.s. In the meantime, we'll just alternate our usage of the web app so only a few folks are using it at once, which is totally workable.

The URL of the shiny app is not opening, got 404?

Not sure what the root of the problem is, but it's impossible to submit any file on https://site.shinyserver.dck.gmw.rug.nl/ggplotgui/: file upload goes smoothly, but upon hitting the "Submit datafile" button the server disconnects and no data is loaded. Local version works fine.

For the sake of context, my request header looks as follows:

Hi
is there some possibility to subset the data (eg by selecting specific groups in one or more variables) through the application?
I think it would facilitate the useres a lot !

Using the GitHub example:

ggplot_shiny(mpg)

1) If you select the [ ggplot ] tab, ggplot plot is shown ok.
But....
2) If you select the [ plotly ] tab, error msg appears instead of plotly plot.
"Error: cannot open file '~/R/i686-pc-linux-gnu-library/3.4/plotly/R/sysdata.rdb': No such file or directory".

Ubuntu Linux 14.04 32-bit, R version 3.4.1 and latest version Rstudio
plus Plotly PKG installed: version 4.7.1.90...

Wouldn't it make more sense to use fill instead of colour in Boxplot and Violin plots?

With colour (now):

With fill (proposed):

The link https://site.shinyserver.dck.gmw.rug.nl/ggplotgui/ shows the following error:
