\title{Convert upper/lower-case characters in sequence fragments}

\description{Converts sequence fragments in lower or upper case letters}

\usage{
lowerSeq(seqno=0, from=1, to=0)
upperSeq(seqno=0, from=1, to=0)
}
\arguments{
  \item{seqno}{Integer/scalar, Sequence number (buffer number)}
  \item{from, to}{Integer/scalar, Absolute addresses of the begin and the end of the fragment,
  (1 means the first nucleotide and 0 conventionally the last one; 
  from must not be larger than to and both vectors must be the same size)}
}

\examples{

s<-"aaaacgtagctagctagctacccccctagctacgtagattttt"
placeString(s,upper=FALSE)
x<-c(1,21,39)
y<-c(4,28,0)

upperSeq(from=x,to=y)

getSeq()
}
