i trying extract date, time, x, y, s, , dis variables , save them in r data frame. think can find way clean shell script read in r hoping there nice trick in r only. thanks

each of lines appear in json format (but not whole file, cannot parse such). return each line list , make list of results

res <- readlines("test.txt") library(jsonlite) allofit <- sapply(res, fromjson) 

which give list of lists (of lists ..) containing data
