I have a dataframe like this
> dim(anno_maf)  32786 129 > head(anno_maf[1:2,1:4]) Tumor_Sample_Barcode Chromosome Start_Position 1: a chr1 27105930 2: a chr1 3342771 End_Position 1: 27105930 2: 3342771 >
I have a list of genes like
gene name PTEN PTEN MAP3K1 MALAT1 MED12 RUNX1 PIK3CA FBXW7 ARID1A MED12 TAB1
I want to add a column in my dataframe named COSMIC, if a gene in gene list exists in my dataframe Hugo_Symbol column, put a yes for this gene if not put a no; Finally my data frame has an extra column as COSMIC in which I have yes or no in Hugo_Symbol column based on the existence of genes in my gene list
Can you help me please?
