Will machine learning methods such as performing random forest on compositional data (as we have relative abundances for the genera) require any type of data transformation?
@@Riffomonas i see. what I am thinking of and facing is that i have some entries like a code D alphabit d digits DDD-ddd-DDD this patter could repeat fully or partially e.g. DD-dd-DDD-ddd-dddd DDD-ddd-DDD-DDD-ddd-DDD the delimiter is always there
@@ahmed007Jaber Ah, maybe try using the separate function. If you look back through past episodes I have one in there on how to use it. Basically, it lets you separate a column by a delimeter into new columns
@@Riffomonas HI Pat, thank you for the effort you put in replying and sharing knowledge. your comments clicked with me. did look quickly at the aforementioned video and tried the following in regex to match another pattern str_extract(x, pattern= "(........) | (......)") it worked like a charm
