Delete duplicate rows from all oTree app data frames and all_apps_wide.

delete_duplicate(oTree)

Arguments

oTree

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

Value

This function returns a duplicate of the original oTree list of data frames but without duplicate rows in all app data frames and all_apps_wide. This function has no effect on the data frames Time and Chats.

This function does NOT add information to $info$deleted_cases, because it does not delete any important information but only cleans up a messy data import.

However, the function adjusts info$initial_n, if an all_apps_wide data frame exists.

Examples

# Set data folder first
withr::with_dir(system.file("extdata", package = "gmoTree"), {

# Import all oTree files in this folder and its subfolders
oTree <- import_otree()
})
#> Warning: You have stored all_apps_wide globally but also room-specific. This function will import both of them. (Globally, the files are saved as "all_apps_wide_." Room-specific, the files are saved as "All apps - wide-" or "all_apps_wide-.") After importing the data, make sure nothing is there twice! (Advice: You may use delete_duplicate() to remove duplicate rows of all oTree data frames.

# First, show some row numbers
print(paste(nrow(oTree$all_apps_wide), nrow(oTree$survey),
nrow(oTree$Time), nrow(oTree$Chats)))
#> [1] "104 88 878 95"

# Delete duplicate rows
oTree <- delete_duplicate(oTree)

# Show row numbers again
print(paste(nrow(oTree$all_apps_wide), nrow(oTree$survey),
nrow(oTree$Time), nrow(oTree$Chats)))
#> [1] "59 55 878 95"
