Compute the number of sequences of values in a vector that meets conditions of length and magnitude.
You can install the development version of nseq from GitHub with:
# install.packages("remotes")
::install_github("rfsaldanha/nseq") remotes
On this vector, how many sequences of values present at least 3 consecutive observations with values equal or greater than 5?
library(nseq)
<- c(8,15,20,8,1,7,8,0,-2,5,9,12,0,-1,4,2,3,1)
vec
trle_cond(vec, a_op = "gte", a = 3, b_op = "gte", b = 5)
#> [1] 2
And how many sequences of values have exactly 3 consecutive observations with values equal or greater than 5?
trle_cond(vec, a_op = "e", a = 3, b_op = "gte", b = 5)
#> [1] 1
