Compute the number of sequences of values in a vector that meets conditions of length and magnitude.

## Installation

You can install the stable release from CRAN.

```
install.packages("nseq")
library(nseq)
```

Or install the development version of from GitHub:

## Example

On this vector, how many sequences of values present at least 3 consecutive observations with values equal or greater than 5?

```
library(nseq)
vec <- c(8,15,20,8,1,7,8,0,-2,5,9,12,0,-1,4,2,3,1)
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
```
