Read Protein Sequences in FASTA Format
Description
This function reads protein sequences in FASTA format.
Usage
readFASTA(
file = system.file("protseq/P00750.fasta", package = "protr"),
legacy.mode = TRUE,
seqonly = FALSE
)
Arguments
file |
Path to the file containing the protein sequences
in FASTA format. If it does not contain an absolute or
relative path, the file name is relative to the current
working directory, |
legacy.mode |
If set to |
seqonly |
If set to |
Value
Character vector of the protein sequences.
The three returned argument are just different forms of the same output. If one is interested in a Mahalanobis metric over the original data space, the first argument is all she/he needs. If a transformation into another space (where one can use the Euclidean metric) is preferred, the second returned argument is sufficient. Using A and B is equivalent in the following sense.
