Examples

## Check for a homogenous sequence
seq <- c(1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2)
checkTH(seq)

## Check for a heterogenous sequence
seq <- c(1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,1,2,2,1,1,2,2,1,1,2,2,1,1,2,2,1,1,2,2,1,1)
checkTH(seq)

Example output

[1] "Time homogeneity present in given sequence"
[1] "Time homogeneity absent in given sequence"
