[R] For help in R coding

Say you have the string x in a matrix

x<-c('a,..gGGtTaac<!T','caaGGTT,,.!!@CC')
x<-matrix(x)

remove all punctuation:

x1<-gsub('[[:punct:]]','',x)
x1

convert all letter to lowercase

x2<-gsub('(\\w*)','\\L\\1',x1,perl=T)
x2

now for each row split the string and table it. apply over all rows in the
matrix

apply(x2,1,function(x) table(strsplit(x,'')))

HTH,
Daniel
