Arguments

x

[sq]

Examples

# Creating objects to work on:
sq_ami <- sq(c("MIAANYTWIL","TIAALGNIIYRAIE", "NYERTGHLI", "MAYXXXIALN"),
             alphabet = "ami_ext")
sq_dna <- sq(c("ATGCAGGA", "GACCGAACGA", "TGACGAGCTTA", "ACTTTAGC"),
             alphabet = "dna_bsc")

# Extracting type of sq objects:
sq_type(sq_ami)
#> [1] "ami_ext"
sq_type(sq_dna)
#> [1] "dna_bsc"

# Classes are tightly related to these types:
class(sq_ami)[1]
#> [1] "sq_ami_ext"
class(sq_dna)[1]
#> [1] "sq_dna_bsc"
