Time arithmetics with “zoo” objects¶
options(jupyter.rich_display=FALSE) # Create output as usual in R
The following makes use of the zoo package. You may need to install it from
CRAN using the code
install.packages("zoo")
if you want to run this on your computer. (The
package is already installed on the notebook container, however.)
library(zoo)
Attaching package: ‘zoo’
The following objects are masked from ‘package:base’:
as.Date, as.Date.numeric
The file “zpresidents.RData” was created in an earlier example.
load("zpresidents.RData")
zpresidents_1 <- zpresidents[1:4]
zpresidents_2 <- zpresidents[3:6]
zpresidents_1 + zpresidents_2

presidents_1 <- presidents[1:4]
presidents_2 <- presidents[3:6]
presidents_1 + presidents_2
