R – as.data.frame() Function Example
Example 1: Basic example of as.data.frame() Function in R
R
# R program to convert object to data frame # Creating Vectors x1 <- c (1, 2, 3, 4) x2 <- c ( "a" , "B" , "C" , "D" ) x3 <- c ( "hello" , "Geeks" , "for" , "geeks" ) # Creating list of vectors x <- list (col1 = x1, col2 = x2, col2 = x3) x # Converting list to data frame as.data.frame (x) |
Output:
$col1 [1] 1 2 3 4 $col2 [1] "a" "B" "C" "D" $col2 [1] "hello" "Geeks" "for" "geeks" col1 col2 col2.1 1 1 a hello 2 2 B Geeks 3 3 C for 4 4 D geeks
Example 2:
R
# R program to convert object to list # Converting pre-defined dataset to list x < - as.list (BOD) x # Converting list to data frame as.data.frame (x) |
Output:
$Time [1] 1 2 3 4 5 7 $demand [1] 8.3 10.3 19.0 16.0 15.6 19.8 attr(, "reference") [1] "A1.4, p. 270" Time demand 1 1 8.3 2 2 10.3 3 3 19.0 4 4 16.0 5 5 15.6 6 7 19.8
