bookdata.frame() Function

The data.frame() function creates a data frame from vectors or lists. Each vector becomes a column, and its variable name is used as the column name.

Example

12345678
# Data name <- c("Alex", "Julia", "Finn") age <- c(24, 43, 32) gender <- c("M", "F", "M") # Create a data frame test <- data.frame(name, age, gender) test
copy

The resulting data frame has three columns (name, age, and gender), with column names automatically taken from the variable names.

Tarefa
