truncate(.data, keep_rows = FALSE)
Arguments
.data |
A data frame or matrix to be truncated |
keep_rows |
Logical. If TRUE, replaces non-NA values with NA instead of removing all data |
Value
An empty data frame or matrix with the same structure as the input
Examples
# Completely empty a data frame
df <- data.frame(x = 1:3, y = 4:6)
truncate(df)
# Replace non-NA values with NA while keeping structure
