json - Iteratively read a fixed number of lines into R -


i have josn file i'm working contains multiple json objects in single file. r unable read file whole. since each object occurs @ regular intervals, iteratively read fixed number of lines r.

there number of questions on reading single lines r have been unable extend these solutions fixed number of lines. problem need read 16 lines r @ time (eg 1-16, 17-32 etc)

i have tried using loop can't seem syntax right: 

## file file <- "results.json"  ## create connection con <- file(description=file, open="r")  ## loop on file connection for(i in 1:1000) {   tmp <- scan(file=con, nlines=16, quiet=true)   data[i] <- fromjson(tmp) }

the file contains on 1000 objects of form:

{   "object": [     [       "a",       0     ],     [       "b",       2     ],     [       "c",       2     ]   ] }

with @tomtom inspiration able find solution. 

## file file <- "results.json" ## loop on file  for(i in 1:1000) {   tmp <- paste(scan(file=file, what="character", sep="\n", nlines=16, skip=(i-1)*16, quiet=true),collapse=" ")   assign(x = paste("data", i, sep = "_"), value = fromjson(tmp)) }

i couldn't create connection each time tried connection close before file had been read. got rid of step.

i had include what="character" variable scan() seems expect number default.

i included sep="\n", paste() , collapse=" " create single string rather vector of characters scan() creates default.

finally changed final assignment operator have bit more control on names of output.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
