R - as.data.frame() Function Example
Example 1: Basic example of as.data.frame() Function in 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 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
