RESOURCERER.annotation.to.ID {SIM} | R Documentation |
Get annotation out of the RESOURCERER annotation file and link them to expression data with help of expression ID's
RESOURCERER.annotation.to.ID(data = expr.data, poslist = poslist_expr, col.ID.link = 1, col.poslist.link = 1)
data |
data.frame with expression data including an expression ID column. |
poslist |
data.frame containing the RESOURCERER annotation file |
col.ID.link |
numeric value, specifying the column of data that contains the ID to link with the poslist . |
col.poslist.link |
numeric value, specifying the column of poslist that contains the ID to lin
k with the data . |
This function will output the inserted dataset, including the necessary, for integrated.analysis, a
nnotation columns: "CHROMOSOME"
, "STARTPOS"
and "Symbol"
out of the inserted RESOURCE
RER annotation file poslist
.
A data.frame is returned, containing a dataset with annotation columns which can be used for integrated.analysis
