search for: row8

I guess this has a simple solution: I have matrix 'mat1' which has row and column names, e.g.: A B C row1 0 0 0 row2 0 0 0 .... rown 0 0 0 I have a another matrix 'mat2', essentially a subset of 'mat1' where the rownames are all in 'mat1' e.g.: B row3 5 row8 6 row54 7 I want to insert the values of matrix mat2 for column B (in reality it could be some or all of column names A, B or C, etc.) (same name in both matrices if that matters - rownames of mat2 guaranteed to be in mat1) into matrix mat1 where the rownames match, so final desired result is:...

Hello everyone, I have a matrix with 8000 rows. If I want to select every 8 rows, (i.e. row1, row2, ..., row8), what should I do? Appriciate for any hints! Thanks a lot!

Hi, It is not that clear. If VAR1 is a match between columns AB001A, AB0002A, VAR2? between AB001A, AB362 and VAR3 between AB0002A and AB362: Also, I assume row8 match would be taken as 1. dat1<- read.table(text=" ? S.No AB001A AB0002A AB362 ?? 1?? -/-??????? C/C?? A/A??????????????????????? ??? 2?? C/C??????? C/C?? A/A??????????????????????? ??? 3?? C/C??????? C/C?? A/A??????????????????????? ??? 4?? C/C???????
