\title{
SDF data blocks to matrix
}
\description{
Convert data blocks in \code{SDFset} to character matrix with
\code{datablock2ma}, then store its numeric columns as numeric matrix and its
character columns as character matrix.  }
\usage{
datablock2ma(datablocklist = datablock(sdfset), cleanup = " \\\(.*", ...)   

splitNumChar(blockmatrix = blockmatrix)

}
\arguments{
  \item{datablocklist}{
\code{list} of data block vectors; can be created with \code{datablock(sdfset)}
}
  \item{blockmatrix}{
\code{matrix} returned by \code{datablock2ma} 
}
  \item{cleanup}{
\code{character} pattern to be used to clean up the name fields of the data block vectors; the exact pattern matches are replaced by nothing (deleted).
}
  \item{\dots}{
option to pass on additional arguments
}
