ControlCode is a matrix representing certain regular expression pattern and the control status of the spotted probe sequences. This function uses `grep' searches for matches to `pattern' (its first argument) within the character vector `x' (second argument).
maGenControls(Gnames, controlcode, id = "ID")
Gnames |
An object of class matrix , data.frame or marrayInfo
which contains description of spotted probe sequences. |
controlcode |

the column number of column name in Gnames that
contains description of each spot on the array. |
