buildSNPannotation.

colname |
character string comprising the name of the column of |
max.length |
integer specifying the maximum number of genes associated with the respective
SNP that should be stored in the data frame. By default, the first two genes are retained.
Shortened entries are marked by |

character string specifying the separation symbol between the different genes. |
add.ldots |
