More than on loop??
hello every one, How to function more than one loop in R? I have the following problem to be solved with the a method of three loops, can you help me please? The data is attached with this message. The data is composed of two parts, cleaved (denoted by ?cleaved?) and non cleaved (denoted by ?noncleaved?). ? to access to the ith peptide, you can use X$Peptide[i] ? to access to the ith label,

Calculating a table of symbol frequencies
Hello all: I have a protein sequence alignment in a data frame (align1, 72 x 236), where each row is a protein and each column a site in the alignment. AA is vector of amino acid symbols plus "-" (gap). I can calculate amino acid frequencies at each site by: >align1.F <- matrix(0,nrow=22,ncol=236,dimnames=list(AA,seq(1:236))) >for(i in 1:236) >

analyze amino acid sequence (composition)of proteins
Dear R-helpers: thank your for your attention. i am a newer to R and i am doing some protein category classification based on the amino acid sequence.while i have some questions urgently. 1. any packages for analysis amino acid sequence 2. given two sequences "AAA" and "BBB",how can i combine them into "AAABBB" 3. based on "AAABBB",how can i get some

Calculating symbol (letter) frequencies
Hello: I am attempting to use R to analyze amino acid frequencies in aligned protein sequences and need some help. So far, I have imported my sequence alignment into a data frame (lets call it "alignment") with each site in one column, so that I have a data frame consisting of columns of letters (the 21 amino acid symbols plus "-") with row names being the corresponding

Package for Molecular Properties
All Is there a package or library that will, given a nucleotide sequence 1. calculate the extinction coefficient at 260 nm for (Beer-Lambert's law) 2. calculate molecular weight 3. return it's complementary sequence I was able to find several packages that can do similar calculations for an amino acid sequence for proteins but none for nucleic acids. Any pointers, etc. would be

Pattern Matching within Vector?
Dear mailing list, I'm stuck with a tricky problem here - at least it seems tricky to me, being not really talented in pattern matching and regex matters. I'm analysing amino acid mutations by position and type of mutation. E.g. (fictitious example) in position 92, I can find L92V, L92MV, L92I... L is in this example the wild-type amino-acid, and everything behind the position number is

How to do the same thing for all levels of a column?
Dear all, I am a R beginner, and I am looking for a way to do the same thing for all levels of a column in a table. Basically, I have a bunch of protein sequences composed of different amino acid residues, and each residue is represented by an uppercase letter. I want to calculate the ratio of different amino acid residues at each position of the proteins. Here is an example table: Proteins

Package(s) for making waffle plot-like figures?
Dear all, I am trying to make a series of waffle plot-like figures for my data to visualize the ratios of amino acid residues at each position. For each one of 37 positions, there may be one to four different amino acid residues. So the data consist of the positions, what residues are there, and the ratios of residues. The ratios of residues at a position add up to 100, or close to 100 (more on

aaMI
hi i am new to R language. I want to use aaMI package which calculates the amino acid mutual interaction for a given protein sequence.

how to order each element according to alphabet
Hi there, I have a large amino acid csv file like this: input.txt: P,LV,Q,Z P,VL,Q,Z P,ML,QL,Z There is a problem with this file, since LV and VL are in fact the same thing. How do I order each element according to alphabetical order so that the desired output would look like: output.txt: P,LV,Q,Z P,LV,Q,Z P,LM,LQ,Z -- View this message in context:

Best HMM package to generate random (protein) sequences?
Dear All, I would like to generate random protein sequences using a HMM model. Has anybody done that before, or would you have any idea which package is likely to be best for that? The important facts are that the HMM will be fitted on ~3 million sequential observations, with 20 different states (one for each amino acid). I guess that 2-5 hidden states should be enough, and an order of 3 would

Appropriate regression model for categorical variables
Dear users, In my psychometric test i have applied logistic regression on my data. My data consists of 50 predictors (22 continuous and 28 categorical) plus a binary response. Using glm(), stepAIC() i didn't get satisfactory result as misclassification rate is too high. I think categorical variables are responsible for this debacle. Some of them have more than 6 level (one has 10 level).
