[R] Substring of a character column

[LogLord]

Hi,

I have a dataframe with a rather complicated descriptive column (V9):

> test3[(1:3), ]
     V1     V4     V5
10 1   4559   7173
17 1  58954  59871
19 1 357522 358458

V9
10 ID=NM_182905.1;Name=NM_182905;Alias=FLJ00038;Note=hypothetical protein
LOC375690
17 ID=NM_001005484;Alias=OR4F5;Note=olfactory receptor%2C family 4%2C
subfamily F
19 ID=NM_001005224.1;Name=NM_001005224;Alias=OR4F3;Note=olfactory
receptor%2C family 4%2C subfamily F
> 

I have problems to extract two strings from this column (V9). First I need
the "ID=..." and second I need the "Alias=..." both in seperate columns. I
tried it with substr() but due to the different length and no wildcard
allowance it did not work.

Would be glad for any help!

Thanks in advance.
