Hello
I have a data frame as below
V1 V2 V3 V4 V5 V6
chr1 18884 C CAAAA 2 0
chr1 135419 TATACA T 2 0
chr1 332045 T TTG 0 2
chr1 453838 T TAC 2 0
chr1 567652 T TG 1 0
chr1 602541 TTTA T 2 0
on which I want to perform complex rearrangement such that:
if V3 is a string >1 (i.e line 2) then I generate 2 new columns where
first new column = V2-1 & second new column = V2+(length of string in V3)+1
therefore, for line 2 output would look like:
chr1 135419 TATACA T 2 0 135418 135426
if length of string in V3 = 1 and V4=string of length>1 (i.e. line 1) then
first new column = V2 & second new column = V2+2
output for line 1 would be:
chr1 18884 C CAAAA 2 0 18884 18886
I am not sure:
a) how to use R to substitute the length of the string in V3 with the
number representing this length
b) whether apply would be best to use here
Thanks
