R-Shiny错误：“ renderDataTable”和“ server = FALSE”

Question

My app uses

drop_download(path = path1, local_path = path2)
d <<- read.csv(path2)

to read the data.frame, d, where d is a global variable (though I am not sure whether this piece of information is relevant).

And I have

output$t <- DT::renderDataTable(d, server=FALSE) 

which throws an error:

Error: C stack usage  15923744 is too close to the limit

However, if I comment server=FALSE then it runs smoothly.

Could anyone explain what is going on and what the implications of commenting out server=FALSE ?

Answer 1

This is explained in ?renderDT . With server = FALSE , all the data are sent to the client-side (the browser), while only the displayed data are sent to the browser with server = TRUE . You get an error because your dataset is too big, and sending it entirely to the browser would slow down the app or even crash it. Using server = FALSE can simplify some things, for example you don't need to use a proxy when you edit some cells. But if you don't modify the table contents (editing the cells for example), using server=TRUE does not cause any complication.
