Read the records of formr data_quality items

A survey page that holds a data_quality item stores one record for that page: a JSON object of counts, durations and yes/no values about the browser and about how the answers were made. dq_parse() turns such records into a data frame with one row per page.

Usage

dq_parse(x)

Arguments

x

a character vector of JSON records, typically the data_quality columns of one participant. Missing and empty values, and values that are not JSON, are dropped.

Value

A data frame with one row per record and one column per field; an empty data frame if x holds no record.

Details

Records never hold what was typed, mouse paths, clipboard content, an IP address or a device fingerprint. Their fields are described in formr's documentation for administrators.

See also

dq_flags() to turn the records of one participant into indicators, dq_flags_by_session() to do so for a whole results table.

Examples

dq_parse(c('{"v":2,"ld":1,"keys":12,"pd":3}', NA, '{"v":2,"ld":1,"keys":40,"pd":5}'))
#>   v ld keys pd
#> 1 2  1   12  3
#> 2 2  1   40  5
