R Quick Tip: Upload multiple files in shiny and consolidate into a dataset
In shiny, you can use the
fileInput with the parameter
multiple = TRUE to enable you to upload multiple files at once. But how do you process those multiple files in shiny and consolidate into a single dataset?
The bit we need from shiny is the
We can use
lapply() with data.tableâ€˜s
fread() to read multiple CSVs from the
fileInput(). Then to consolidate the data, we can use data.tableâ€˜s
rbindlist() to consolidate these into a dataset.
For more info on using data.table for consolidating CSVs, read my post on
If you wanted to process things other CSVs then you might consider alternative libraries, and of course, you donâ€™t just need to put them all into one big table.
View the code on Gist.
