View source: R/conjointTriad.R
This function calculates the grouped tripeptide composition with the conjoint triad grouping type.
1 | conjointTriad(seqs, normalized = TRUE, label = c())
|
seqs |
is a FASTA file with amino acid sequences. Each sequence starts with a '>' character. Also, seqs could be a string vector. Each element of the vector is a peptide/protein sequence. |
normalized |
is a logical parameter. When it is FALSE, the return value of the function does not change. Otherwise, the return value is normalized using the length of the sequence. |
label |
is an optional parameter. It is a vector whose length is equivalent to the number of sequences. It shows the class of each entry (i.e., sequence). |
This function returns a feature matrix. The number of rows equals to the number of sequences and the number of columns is 7^3.
