Data object for qualitative data analysis.

Source: R/qda.R
qda.Rd

This function creates an object to manipulate data for qualitative analysis. The data is stored in a SQLite database by default, but can be configures to work with any SQL database through the DBI R package interface. Although you can manipulate the SQL database directly, we recommend using the methods (functions) defined in the returned object. This will ensure data integrity.

Usage

qda(
  file,
  users_passphrase = "ShinyQDA",
  users = c("admin"),
  users_names = users,
  users_passwords = rep("password", length(users)),
  users_is_admin = rep(TRUE, length(users))
)

Arguments

Value

a list with functions to access and edit qualitiative data.
