Hi,
I am trying to edit a data frame such that the string in the first line is
appended onto the beginning of each element in the subsequent rows. The data
looks like this:
> df
V1 V2 V3 V4
1 DPA1* DPA1* DPB1* DPB1*
2 0103 0104 0401 0601
3 0103 0103 0301 0402
.
.
and what I want is this:
>dfnew
V1 V2 V3 V4
1 DPA1* DPA1* DPB1* DPB1*
2 DPA1*0103 DPA1*0104 DPB1*0401 DPB1*0601
3 DPA1*0103 DPA1*0103 DPB1*0301 DPB1*0402
any help is much appreciated, I am new to this and struggling.
