Assign a variable from one of the app data frames to all_apps_wide.

assignv_to_aaw(oTree, app, variable, newvar, resafter = NULL)

Arguments

oTree

A list of data frames that were created by import_otree().

app

Character. The data frame from which the variable is taken.

variable

Character. The name of the variable that should be assigned to all_apps_wide.

newvar

Character. The name of the newly created variable in the all_apps_wide data frame.

resafter

Character. The name of the variable that precedes the new variable. If NULL, the new variable will be placed at the end of the data frame.

Value

This function returns a duplicate of the original oTree list of data frames but with an additional column in the all_apps_wide data frame that contains the variable in question.

Examples

# Use package-internal list of oTree data frames
oTree <- gmoTree::oTree

# Create a new variable
oTree$survey$younger30 <- ifelse(oTree$survey$player.age < 30, 0, 1)

# Assign the variable younger30 to all_apps_wide
oTree2 <- assignv_to_aaw(
  oTree = oTree,
  app = "survey",
  variable = "younger30",
  newvar = "younger30")
#> Warning: New variable is created. However, there is an unequal number of participants in "all_apps_wide" (29) and app "survey" (25). Did you forget to delete dropouts and empty cases or did you forget to import app data? Sometimes, this can happen if you import data from within a session or room where you can only import "all_apps_wide" but not the separate app data, time data or chat data.

# Show the new variable in the all_apps_wide data frame
