What is the easiest way to assign names to a vector? Explain with an example
In R, names() function is used to assign names to each element in a vector. Let us assign a vector named temps which contains temperature of seven days.
temps <- c(72,71,68,73,69,75,71)
Now we do not know the temperature corresponds to which weekdays. For that, we can assign names() function to assign weekdays to the temperature
names(temps) <- c('Mon','Tue','Wed','Thu','Fri','Sat','Sun')
Now we can see the following output
temps
Mon 72
Tue 71
Wed 68
Thu 73
Fri 69
Sat 75
Sun 71
