AAstat {seqinr} | R Documentation |
Returns simple protein sequence information including the number of residues, the percentage physico-chemical classes and the theoretical isoelectric point.
AAstat(seq, plot = TRUE)
seq |
a protein sequence as a vector of chars |
plot |
if TRUE , plots the presence of residues splited by
physico-chemical classes along the sequence. |
A list with the three following components:
Compo |
A factor giving the amino acid counts. |
Prop |
A list giving the percentage of each physico-chemical classes (Tiny, Small, Aliphatic, Aromatic, Non-polar, Polar, Charged, Positive, Negative). |
Pi |
The theoretical isoelectric point |
