How to find if the numbers are continuous in R?
r, statistics
Solution
Something like this?
x <- c(1:5, 8:10, 13:15) # example data
unname(tapply(x, cumsum(c(1, diff(x)) != 1), range)
# [[1]]
# [1] 1 5
#
# [[2]]
# [1] 8 10
#
# [[3]]
# [1] 13 15
Another example:
x <- c(1, 5, 10, 11:14, 20:21, 23)
unname(tapply(x, cumsum(c(1, diff(x)) != 1), range))
# [[1]]
# [1] 1 1
#
# [[2]]
# [1] 5 5
#
# [[3]]
# [1] 10 14
#
# [[4]]
# [1] 20 21
#
# [[5]]
# [1] 23 23
Problem
I have a range of values ``` c(1,2,3,4,5,8,9,10,13,14,15) ``` And I want to find the ranges where the numbers become discontinuous. All I want is this as output: ``` (1,5) (8,10) (13,15) ``` I need to find break points. I need to do it in R.
