I have a problem with the toJSON function in RJSONIO package in R. Values seem to be rounded when reading from a data frame.
I would like to understand whether this is a bug or something deeper within R.
Here is a reproducible example:
sal <- structure(list(a = c(1250.00, 1250.04, 1250.08, 1250.12, 1250.16, 1250.2, 1250.24),
b = c(1, 1.06, 1.12, 1.18, 1.24, 1.3, 1.36)),
.Names = c("a", "b"), row.names = c(NA, 26L), class = "data.frame")
When I run toJSON function from RJSONIO:
library(RJSONIO)
RJSONIO::toJSON(sal)
[1] "{\n \"a\": [ 1250, 1250, 1250.1, 1250.1, 1250.2, 1250.2, 1250.2 ],\n\"b\": [ 1, 1.06, 1.12, 1.18, 1.24, 1.3, 1.36 ] \n}"
For comparison, I get this result using toJSON function from rjson:
library(rjson)
rjson::toJSON(sal)
[1] "{\"a\":[1250,1250.04,1250.08,1250.12,1250.16,1250.2,1250.24],\"b\":[1,1.06,1.12,1.18,1.24,1.3,1.36]}"
The RJSONIO package appears to be rounding the values. For example 1250.04 is rounded to 1250.
Here is my relevant sessionInfo()
R version 3.2.1 (2015-06-18)
Platform: i686-pc-linux-gnu (32-bit)
Running under: Ubuntu 14.10
other attached packages:
[1] rjson_0.2.15 RJSONIO_1.3-0
Can anyone please suggest why this is happening?
There's a digits parameters for that in RJSONIO:toJSON
library(RJSONIO)
toJSON(sal, digits = 6)
[1] "{\n \"a\": [ 1250, 1250.04, 1250.08, 1250.12, 1250.16, 1250.2, 1250.24 ],\n\"b\": [ 1, 1.06, 1.12, 1.18, 1.24, 1.3, 1.36 ] \n}
