JSON practice (2)
We prepared two more JSON strings in the sample code. Can you change them and call jsonlite
's fromJSON()
function on them, similar to the previous exercise?
This exercise is part of the course
Intermediate Importing Data in R
Exercise instructions
- Remove characters from
json1
to build a 2 by 2 matrix containing only 1, 2, 3 and 4. CallfromJSON()
onjson1
. - Add characters to
json2
such that the data frame in which the json is converted contains an additional observation in the last row. For this observations,a
equals 5 andb
equals 6. CallfromJSON()
one last time, onjson2
.

# jsonlite is already loaded
# Challenge 1
json1 <- '[[1, 2], [3, 4], [5, 6]]'
