DT in Shiny and R: Custom number formatting

Question

I have a shiny-app that displays a datatable using the DT-package. What I want is to be able to format columns in a custom way. For example I want a currency value

Answer 1

You can change the position of the currency symbol in the .js file from the datatable package.

Edit the line of the DTWidget.formatCurrency function

 $(thiz.api().cell(row, col).node()).html(currency + markInterval(d, interval, mark));

to simply

 $(thiz.api().cell(row, col).node()).html(markInterval(d, interval, mark) + currency);

in the DT/htmlwidgets/datatables.js file in the directory of your R librarys.

As for the € Symbol,

formatCurrency(c('cur'), currency = "\U20AC", interval = 3, mark = ",", digits = 2)

does work for me, thats what you tried and you don't see any symbol?
