RDocumentation: as_tibble

Beta

Note that this notebook was automatically generated from an RDocumentation page. It depends on the package and the example code whether this code will run without errors. You may need to edit the code to make things work.

if(!require('tibble')) {
    install.packages('tibble')
    library('tibble')
}

l <- list(x = 1:500, y = runif(500), z = 500:1)
df <- as_tibble(l)

m <- matrix(rnorm(50), ncol = 5)
colnames(m) <- c("a", "b", "c", "d", "e")
df <- as_tibble(m)

# as_tibble is considerably simpler than as.data.frame
# making it more suitable for use when you have things that are
# lists
