### Convert JSON-stat to R and Back

Source: https://github.com/ajschumacher/rjstat/blob/master/README.md

Demonstrates converting JSON-stat data to R data frames and then back to JSON-stat, highlighting compatibility.

```r
library(rjstat)

# Assuming irisJSONstat is already created from the previous example
# irisJSONstat <- toJSONstat(list(iris=irises))

head(fromJSONstat(irisJSONstat)[[1]])
```

--------------------------------

### Read JSON-stat Data

Source: https://github.com/ajschumacher/rjstat/blob/master/README.md

Reads data from a JSON-stat formatted URL into a list of R data frames. Supports reading by labels or IDs.

```r
library(rjstat)

oecd.canada.url <- "https://json-stat.org/samples/oecd-canada.json"

# Read from JSON-stat to a list of data frames:
results <- fromJSONstat(readLines(oecd.canada.url))
names(results)

# Read using IDs rather than labels:
results <- fromJSONstat(readLines(oecd.canada.url), naming="id")
names(results)
```

### Convert R Data to JSON-stat

Source: https://github.com/ajschumacher/rjstat/blob/master/README.md

Converts a list of R data frames into a JSON-stat formatted string. Requires data frames to have exactly one value column.

```r
library(rjstat)
library(reshape)

irises <- melt(cbind(iris, Specimen=rep(1:50, 3)),
               id.vars=c("Species", "Specimen"))
irisJSONstat <- toJSONstat(list(iris=irises))
cat(substr(irisJSONstat, 1, 76))
```
