seedRegions {microRNA} | R Documentation |
The seed region of a microRNA consists of a set of nucleotides at the 5' end of the microRNA, typically bases 2 through 7, although some times 8 is used.
seedRegions(x, start = 2, stop = 7)
x |
A vector of microRNA sequences. |
start |
The start locations, can be a vector. |
stop |
The stop locations, can be a vector. |
We use substr
to extract these sequences.
A vector of the same length as x
with the substrings.
