[R] split string into individual valus while reading in R
It looks like my question is not clear, I have not get any suggestion, yet let me reiterate my problem: My data looks like this to be read from a text file. As I provided earlier the A, B, and H in V4 column has much longer chain. V1 V2 V3 V4 1_1 ch1 0.0 AHAH 1_2 ch1 0.20 AHAAA ...........................so on I want to read this as (splitting AHB........into individual characters) V1 V2 V3 V4 V5 V6 V7 V8 1_1 ch1 0.0 A H A H NULL 1_2 ch1 0.20 A H A A A Any trick to do this?
