Splitting vector
Hi,
Try:
vec1<- "mue#d/sjbijk at ruepvnvbnceiicrpgxkgcyl@keduhqvqi/ubudvxopddpfddgitrynzshzdcwgneyffrkpbxwilwqngrsals#geqmtkcpkp/qecgdfa#uag"
library(seqinr)
?res<-lapply(0:4,function(i) lapply(2:5,function(j) splitseq(s2c(gsub("[#@/]","",vec1)),word=j,frame=i)))
#or
library(stringr)
res1<-lapply(0:4,function(i) lapply(2:5,function(j) splitseq(s2c(str_replace_all(vec1,"[[:punct:]]","")),word=j,frame=i)))
#or

Sequence analysis
Hiya,
I am trying to look at the similarities between a number of
sequences, for example i am trying to see how similar "ababbbassdaa" is to
"addffggssbbsbbs" I was wondering is the some way for me to see how similar
they are in terms of, for example, number of a's, number of b's, how often a
and ab are consecutive, how often abab is together etc.
Any advice

visualizing nucleotide sequence properties
Hi there,
I am looking for R-packages that can help me visualize properties on
nucleotide sequences. I want to display sequences in the 1-100K base range
as lines and plot features above and below those lines.
Any ideas would be welcome.
Thanks,
Bernd

Loop avoidance and logical subscripts
...ge amounts of data. I assume it's because I don't know how to avoid using
loops. Logical subscripts are more desirable, but I don't know how to
implement them. One example of that issue:
library(seqinr)
GCsequence <- vector()
for( i in 1:(length(data$sequence))) {
c(GCsequence,GC(s2c(data$sequence[i])))->data$GCsequence[i]
}
rm(GCsequence)
How should I speed up that?
Thank you,
Retama

incrementing matrix elements more efficiently
I need to increment cells of a matrix (collusionM). The indexes to increment are in an index (matchIndex). This is some of the code
for (j in 1:(rows-1)) matchIndex[[j]] <- which(mx[j]==mx)
for (j in 1:(rows-1)) collisionM[j,matchIndex[[j]]] <- collisionM[j,matchIndex[[j]]] + 1
I could put them in the same loop but this is slower. The first for statement is fine. It finds the matches

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

Subsetting a large number into smaller numbers and find the largest product
Hello,
I have a big number lets say of around hundred digits. I want to subset
that big number into consecutive number of 5 digits and find the product of
those 5 digits. For example my first 5 digit number would be 73167. I need
to check the product of the individual numbers in 73167 and so on.
The sample number is as follows:
