Vector_lag {EWS} R Documentation

## Vector lag - data processing

### Description

Compute a lagged version of a time series, shifting the time base back by a given number of observations defined by the user. The user must enter three parameters for this function: the vector, the number of lags, and a boolean variable named 'beginning'. If 'beginning'=TRUE, then the lag will be applied at the beginning of the vector whereas if 'beginning'=FALSE, then the lag will be applied at the end of the vector.

### Usage

Vector_lag(Vector_target, Nb_lag, beginning)


### Arguments

 Vector_target Initial vector Nb_lag Number of lag beginning Boolean variable. If 'beginning'=TRUE, the lag is applied at the beginning of the vector. If 'beginning'=FALSE, the lag is applied at the end of the vector.

### Value

A numeric Vector.

### Examples


# NOT RUN {

# Initialize the following vector
vector_example <- as.vector(1:10)

# Use Vector_lag
new_vector <- Vector_lag(Vector_target = vector_example, Nb_lag = 2, beginning = TRUE)

new_vector
# Results:
#> new_vector
#[1]  3  4  5  6  7  8  9 10

#}
